How to play

NumPlay

Key	What it does
Left / Right (or 4 / 6)	Pick a game
OK or EXE (or 5)	Play
Back	Leave a game's main menu to come back here. On the carousel, quit NumPlay
⌫ (backspace)	A moving background behind the carousel: Aurora, Sunset Drive, Plasma, Pastel, Lava Lamp, Ocean, then none again. NumPlay remembers it
Home	Quit, from anywhere

The last card, Settings, can:

• Reset a game's progress, or every game's at once: hold OK on the red button to confirm (levels you made are kept)
• Uninstall the games you don't play, to free up space
• Start as Matrices: NumPlay opens as a plain matrix calculator. Your secret way in opens the games: pick the x,n,t key, var, Toolbox, π, √, Examples in the Toolbox menu, or the Konami code (up, up, down, down, left, right, left, right; LanoCodes17's idea). A small gray hint in the corner names it (turn it off with Show a hint)

Your progress is also copied into a Python script, numplay_saves.py, so updating NumPlay doesn't erase it. Leave it there; if it gets deleted, NumPlay writes it again.

In every game, Back pauses, and the pause menu has a small Quit game button. It always asks first, since Back sits right next to OK.

NumDash

Key	What it does
OK, EXE or Up	Jump. Hold to keep jumping, fly the ship up, or flip the ball's gravity
Back	Pause, or go back in menus
0	Place a checkpoint (practice mode)
⌫	Remove your last checkpoint

Twelve levels, from Stereo Madness to Clubstep, Deadlocked and Dash. The ? button on the main menu shows every key. In the level editor, KEYS on the My Levels screen draws the keyboard with what each key does (it also shows the first time you open the editor).

Crossy Road

Key	What it does
Up, OK or EXE	Hop forward
Left / Right / Down	Hop sideways or back
Back	Pause (then Quit game)

Keep moving, or the eagle gets you. Coins add up across every run and stay saved.

NumBlocks

Key	What it does
Arrows	Look around
, / π / √ / x²	Walk forward / left / back / right (like W, A, S, D)
shift	Jump (twice in Creative: fly)
alpha	Sneak
i	Sprint
OK or EXE	Mine and attack, like the left mouse button (hold it to mine)
Back	Place a block, use, eat, like the right mouse button
var	Inventory (in Creative: every block and item)
1 to 9	Pick a hotbar slot
x,n,t	Drop the item
log	Pick the block you look at
× / ÷	Chat / type a command
ans	Pause
Home	Save and quit

The left thumb looks with the arrows (shift and alpha are just under them), the right one walks. The first time you open NumBlocks it shows these keys. You can change them in Options, then Controls, which also shows the key sheet again. In NumBlocks, Back places blocks, so ans pauses. In the inventory, the arrows move between slots, OK picks up or puts down a stack, EXE one item, and shift with OK sends a stack to the other side. To spread a stack, hold OK and move over the slots: it splits evenly when you let go (hold EXE instead to drop one in each). In Creative, the Search Items tab finds blocks as you type, and shift with up or down jumps to the top or bottom of a tab. Commands like /gamemode and /give work in worlds with Allow Cheats on (or after Open to LAN in the pause menu); toolbox finishes a word as you type it. Your world saves as you play and when you quit, and on its own NumBlocks keeps a copy in numblocks_saves.py (inside NumPlay, numplay_saves.py holds it), so installing again doesn't erase your worlds.

On its own, NumBlocks.nwa also has the Nether and the End: portals, fortresses, strongholds and the Ender Dragon, as Minecraft 1.8.8 makes them (NumPlay's NumBlocks stays in the Overworld).

Hollow Knight

Hollow Knight comes as its own app, HollowKnight.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Move, look up and down, aim the nail up or down
Up	Talk, read, rest at a bench, go through a door
OK	Jump
Back	Nail
shift	Dash, once you have the Mothwing Cloak
alpha	Hold to focus and heal, tap to cast a spell
var	Hold for the quick map
toolbox	Inventory
⌫	Pause
Home	Save and quit

Choose Start Game, then a save. Rest at benches to save and to change charms: toolbox, right to Charms, then OK on a charm. In menus, OK or EXE confirms and Back goes back. In the inventory, left and right at the edges change pages; on the map page, OK places markers once you have them, and shift shows or hides the key and the pins. Home saves and quits, as Quit to Menu does. Your saves are also copied into hollowknight_saves.py, so installing the app again doesn't erase them.

Celeste

Celeste comes as its own app, Celeste.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Move, and aim the dash
OK	Jump
Back	Dash, and talk
toolbox	Grab, climb
⌫	Pause
Home	Save and quit

Choose Climb, then a chapter, then Start. Madeline can dash once in the air (twice later on), and grab and climb walls until she gets tired. In menus, OK or EXE confirms and Back goes back. The first time you open Celeste it shows these keys; you can change them in Options, then Keyboard Config. Home saves and quits, and Climb then offers Continue. Your progress is also copied into celeste_saves.py, so installing the app again doesn't erase it. The game's cheat code works too: in the Prologue's hidden room, left of the start, press left, right, var, toolbox, up, up, down, left, toolbox and OK.

NumPowder

NumPowder comes as its own app, NumPowder.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Move the brush (shift: 4 at a time)
OK	Draw with the OK material
Back	Draw with the Back tool (ERASE at first)
toolbox	The materials: left and right pick, up and down change category, OK takes it, shift+OK for Back
var	The menu: How to play, keys, save, load, clear, display, settings, credits
+ and -	The brush's size (shift: its shape)
shift+OK	Draw a line; ⌫ switches to a box or a fill
⌫	Take the material under the brush
alpha	Pause (shift+alpha: one frame)
Home	Save and quit

Pick a material with toolbox, then hold OK to draw it. The bar at the bottom always shows what OK and Back draw with, and the line under it says what the keys do right now. Try sand on water, fire on wood, lava on ice, or draw metal (METL) and touch it with a spark (SPRK). How to play, in the var menu, has more ideas. Home saves, and four save slots keep more; they are also copied into numpowder_saves.py, so installing the app again doesn't erase them.

The Final Earth 2

The Final Earth 2 comes as its own app, FinalEarth2.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Move the cursor, or the focus in menus and windows
shift + arrows	Move the view faster
OK	Open what is under the cursor, choose, build here
Back	Close, stop building, open the game menu
toolbox	Open or close the build menu
var	Go to the buttons and materials at the bottom right, and back
alpha	Pause
+ and -	Zoom in and out
⌫	Destroy the building under the cursor
Home	Save and quit

Choose a scenario or a free play map. Build woodcutters and stone mines for materials, farms for food and houses for your citizens; buildings stack on top of each other. In the build menu, left and right go through the buildings, up and down change the category, and OK picks one; then OK builds where the cursor is, and Back goes back to the menu. Each goal of a scenario tells you what to do next, and ? shows it again. On the speed button, OK switches between normal and double speed, and shift with OK goes through all five speeds. Home saves and quits, and the title then offers Continue. Your city is also copied into finalearth2_saves.py, so installing the app again doesn't erase it.

NumDrive

Key	What it does
Right or 6	Drive forward
Left or 4	Brake and reverse
OK or Back	Pause. Back again resumes
Levels on the pause card	Pick any level

Don't floor it the whole way: too much gas flips the car.

Balatro

Key	What it does
Arrows	Move between cards, Jokers and buttons
OK	Pick a card, or open a Joker or shop item (Buy, Sell, Use)
EXE	Play hand
⌫	Discard
Shift	Sort by rank or suit
Alpha + Left / Right	Move a Joker or a card
Toolbox / Var	Run info / your deck

Buckshot Roulette

Key	What it does

OK or EXE	Use an item, pick up the shotgun, fire
Up / Down	With the shotgun: aim at the Dealer / at yourself
Letter keys	Sign the waiver (EXE signs)
Back	Pause

Shooting yourself with a blank keeps your turn.

Block Blast

Key	What it does
1, 2, 3	Take that block
Arrows	Move it on the board
OK	Place it
Back	Menu (with How to play and Quit)

Fill a row or a column to clear it; blocks never turn. The lines a block would fill light up in its colour before you place it. Clear again within three blocks for a combo, which multiplies the points. The game ends when none of your three blocks fits; your game and best score are saved.

Suika Game

Key	What it does
Left, Right (or 4, 6)	Move the fruit
OK or EXE	Drop it
Back	Menu (with Restart, How to play and Quit)

Drop fruit into the box. Two of the same fruit touching join into the next one up, from cherry to watermelon, and score points; two watermelons vanish. The next fruit is shown in the bubble. The game ends when the box overflows. Your game and best score are saved.

Champion Island

Champion Island comes as its own app, ChampionIsland.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows (or 4, 6, 8, 2)	Walk, and play
OK, EXE or 5	Talk, go through doors, and each sport's action
Back	On the island: the map. In a sport: pause
Home	Save and quit

Sport	Arrows	OK
Table Tennis	Move to the ball	Power shot
Skateboarding	Move and do tricks	Jump and do tricks
Archery	Move	Shoot
Rugby	Move	Pass
Artistic Swimming	Hit the arrow beats
Marathon	Move	Dodge
Climbing	Move	Jump

Every sport shows its rules and keys before it starts. Your progress is also copied into champion_saves.py, so installing the app again doesn't erase it.

Undertale

Undertale comes as its own app, Undertale.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows (or 4, 6, 8, 2)	Walk, move your SOUL, choose
OK, EXE or 5	Talk, read, confirm (Z in the game)
Back or ⌫	Cancel, show the whole text at once (X in the game)
toolbox, shift or var	The menu: ITEM, STAT, CELL (C in the game)
Home	Keep the moment and quit

Name the fallen human, then walk and talk your way through the Ruins, Snowdin, Waterfall, Hotland, the MTT Resort, the CORE and New Home. In a battle, FIGHT attacks (press OK when the bar crosses the middle), ACT checks a monster or does something to it, ITEM eats, and MERCY spares a monster that no longer wants to fight, or flees. Then move your SOUL to dodge; when it turns blue, it falls, and Up jumps; when it turns green, it stays put, and the arrows turn its shield to block. On ice you slide until something stops you. In Snowdin Town, walk into the shop to buy, and into the inn to rest. In Waterfall, walk into a bridge seed to push it into the water, where it blooms into a flower you can walk on; the bell calls the seeds back. A green bullet heals you. Walk up to a star and press OK to SAVE. Home keeps the moment you were at, and the next start is back there. Your save is also copied into undertale_saves.py, so installing the app again doesn't erase it. The Tem Shop in Temmie Village also buys what you carry. In Hotland, steam vents throw you over the lava, orange lasers hit you if you stand still and blue ones if you move, and in a shooting puzzle the arrows push the dark blocks and Z shoots. On the second floor, press the switches as the top conveyor belt carries you past them, and in Mettaton's news report, touch each bomb and defuse it while it's in the DEFUSE ZONE. When Muffet turns your SOUL purple, it keeps to three strings: Up and Down hop between them. In the tile puzzle, red tiles are walls, yellow ones shock you back, orange makes you smell of oranges (and blue water's piranhas bite then), and purple soap slides you on and smells of lemons. When your SOUL turns yellow, OK shoots. At the MTT Resort, the desk rents you a room and the hotel's doors want room service. On the CORE's laser bridge, walk while the power is off and freeze when it comes back on. Mettaton EX's show is won on its ratings: Boast, Pose, a Heel Turn and his brand's food raise them. In New Home, find both keys to unchain the stairs. Asgore breaks MERCY, so you'll have to fight him. Against Omega Flowey, dodge, and reach the ACT button that comes down among a SOUL's attack; once all six SOULs are on your side, reach FIGHT. The game ends at the neutral ending.

Doom

Doom comes as its own app, Doom.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Up / Down	Walk forward / back
Left / Right	Turn
OK	Fire
Back	Use: open doors, press switches
EXE or ⌫	Menu and pause
shift (held)	Strafe with left and right
x,n,t / var	Strafe left / right
alpha (held)	Run
1 to 7	Choose a weapon
toolbox	Automap: the map, the map over the game, the game
+ / −	Screen size; on the automap, zoom
× / ÷ / 0	Automap: follow, grid, the whole map
8 / 9	Automap: mark, clear the marks
√	Brightness
ln / log	Quick Save / Quick Load
π	Pause
ans	Type a cheat code
Home	Keep the moment and quit

Press a key on the title screen for the menu, then choose New Game, Knee-Deep in the Dead and a skill. In menus, OK or EXE confirms and Back goes back; when the game asks a question, OK says yes and Back says no. Read This! shows the keys as they are: Options, Keys gives any key any action, and Options, Cheats has every cheat code. Home keeps the moment you were at, and the next start puts you back there. Save Game has six slots; your saves are also copied into doom_saves.py, so installing the app again doesn't erase them. You can also build Doom.nwa from your own WAD (Doom, Doom II, Freedoom...): see the game's page.

The Binding of Isaac

The Binding of Isaac comes as its own app, BindingOfIsaac.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Walk
8 4 6 2 (or 5)	Cry up, left, right, down
9, shift or ×	Drop a bomb
7, alpha or OK	Use the active item
1, 3 or −	Take the pill or use the card
toolbox, var or x,n,t	Hold to see the whole map
Back	Pause
Home	Keep the run and quit

On the menu, Controls swaps them: the number keys walk and the arrows cry. Every run is a new set of floors, from the Basement down to Mom, her heart and beyond: clear a room to open its doors, find the treasure room, the shop and the boss, and bomb the walls for secret rooms. Keys open the golden doors and chests, coins buy in the shop, and the Devil's and the angel's rooms come after a boss. Win a run to unlock ???, Eve, Samson and Azazel. Home keeps the run, and it is copied into isaac_saves.py, so installing the app again doesn't erase it.

Plants vs. Zombies

Plants vs. Zombies comes as its own app, PlantsVsZombies.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows	Move over the lawn, choose in the menus
1 to 9, 0	Pick a seed packet (from the conveyor belt too)
OK or EXE	Plant, whack a zombie, break a vase, confirm
⌫	The shovel: then OK digs up a plant
Back	Put the seed back, or pause
toolbox	The Almanac, in the menu
Home	Keep the level and quit

Plant your lawn to stop the zombies before they reach your house. Sunflowers make sun, and seeds cost sun: move the cursor over falling sun and coins to pick them up. Each seed recharges after you plant it. At night no sun falls and mushrooms are awake; in the day they sleep unless you plant a Coffee Bean on them. The pool's lanes need Lily Pads, the fog hides the zombies until a Plantern lights it or a Blover blows it away, and on the roof every plant goes in a Flower Pot and only lobbed shots get over the slope. A lawn mower saves each lane once. Before most levels you choose your seeds; on the conveyor-belt levels they come to you. Crazy Dave opens his shop once you find his car key, and the coins zombies drop buy more seed slots, pool and roof cleaners, a rake and Wall-nut First Aid. At the end of the roof, Dr. Zomboss waits in his Zombot: hit his head when he lowers it, put out his fire balls with an Ice-shroom and melt his ice balls with a Jalapeno. Home keeps the level you are playing, and Continue brings it back. Your saves are also copied into pvz_saves.py, so installing the app again doesn't erase them.

Five Nights at Freddy's

Five Nights at Freddy's comes as its own app, FiveNightsAtFreddys.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
← → (or 4 / 6)	Look left and right
7 / 1	The left door / the left light
9 / 3	The right door / the right light
OK, EXE or 8	The monitor up and down
1 to 7	On the monitor: that camera (1, 2 and 4 again for 1B, 1C, 2B, 4B)
Arrows	On the monitor: the camera next to it on the map
0 or ⌫	Mute the phone call
Back	Pause
Home	Keep the night and quit: the next start is back in it

Last from 12 AM to 6 AM, five nights in a row. Light the doorways to see who is there and close the door on them, check the cameras (Foxy comes out of Pirate Cove when they stay down), and watch the power: when it runs out, the doors won't close. The Phone Guy's calls are subtitles, and what you would hear is written at the bottom left. Your nights and stars are also copied into fnaf_saves.py, so installing the app again doesn't erase them.

Sonic the Hedgehog

Sonic the Hedgehog comes as its own app, SonicTheHedgehog.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Arrows (or 4, 6, 8, 2)	Run, look up, duck; Down while running rolls
OK, EXE, 5, 0 or shift	Jump
Back or ⌫	Pause: Resume or Quit game
Home or On/Off	Save and quit: Continue on the title goes back there

Run right to the signpost at the end of each act; each zone's third act ends with Dr. Robotnik and the capsule of animals. When something hits you, you drop your rings; with none you lose a life, and 100 give an extra life. Finish an act with 50 rings and jump into the giant ring for a Special Stage: steer through the turning maze to the Chaos Emerald, away from the GOAL blocks. All six emeralds change the ending. Each act is saved as it starts, and the save is copied into sonic_saves.py, so installing the app again doesn't erase it.

Subway Surfers

Subway Surfers comes as its own app, SubwaySurfers.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Left / Right (or 4 / 6)	Change tracks
Up (or 8)	Jump
Down (or 2)	Roll; in the air, dive down and roll
OK, EXE or 5	Ride a hoverboard: one crash is forgiven
1 / 3	At the start of a run: a headstart / a score booster
Back	Pause (Resume, Quit game), or go back in menus
Home or On/Off	Save and quit

Hit the side of a train or a barrier's edge and you stumble: the Inspector and his dog are right behind you, and a second stumble gets you caught. The yard is the classic one: the orange viaduct and its trees, steel bridges over the water, tunnels, and the orange and lime trains. Run into anything head-on and the run is over, unless you spend keys to be saved. Ramps lead up onto the trains' roofs; Super Sneakers jump high enough to land on them. Missions raise your score multiplier, and coins buy upgrades, items, characters and boards in the shop. Your progress is also copied into subway_saves.py, so installing the app again doesn't erase it.

Hill Climb Racing

Hill Climb Racing comes as its own app, HillClimbRacing.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
Right, OK or EXE (or 6)	Gas; in the air, tilt back
Left (or 4)	Brake, then reverse; in the air, tilt forward
Back	Pause (Resume, Restart, Garage, Quit game)
Home	Keep the run's coins and quit

Drive as far as you can before the fuel runs out or Bill lands on his head. It drives like the real game: the same physics engine (Box2D) with the game's own numbers for every vehicle and stage. Pick up fuel cans on the way, collect coins, and earn more with air time and flips; each stage's levels pay a bonus when you reach their goal, and the next level waits for you on your next run. In the garage, spend coins on new vehicles and their four upgrades, and on new stages: the Desert's dunes, the slippery Arctic, the Cave's ceiling, the Moon's low gravity, the Forest's trees to ram through, with rope bridges along the way. Your coins, upgrades, levels and best distances are saved, and copied into hillclimb_saves.py so installing the app again doesn't erase them.

Cookie Clicker

Cookie Clicker comes as its own app, CookieClicker.nwa: it is too big to share the calculator with NumPlay.

Key	What it does
OK	Click the big cookie
Arrows	Choose in the store (up from its top: the news ticker)
EXE	Buy or sell what is chosen; press the ticker
÷ / ×	Buy or sell / 1, 10, 100 (all, to sell)
shift	Click a golden cookie or a reindeer
var	Pop a wrinkler
x,n,t	Harvest the sugar lump
alpha	The buildings' rows: EXE levels one up or opens its minigame
toolbox	Statistics
⌫	Close a note
Back	Menu: Options, Statistics, Info, Legacy, Santa, Krumblor, Keys, Save
Home	Save and quit

Click the cookie, buy buildings that bake for you and upgrades that make them bake more. Golden cookies give Frenzies, Lucky!, Click frenzies and more; when the elders awaken, wrath cookies and wrinklers come. Level your buildings up with sugar lumps to unlock the Grimoire's spells and the Pantheon's spirits. When you have baked enough, ascend from the Legacy menu: your cookies become heavenly chips to spend on the heavenly upgrades, then you start again stronger. The calculator has no clock, so the bakery only bakes while the game is open, and sugar lumps grow 24 times faster to make up for it. Your bakery is also copied into cookieclicker_saves.py, so installing the app again doesn't erase it.

Level Devil

Level Devil comes as its own app, LevelDevil.nwa: install it on its own.

Key	What it does
Left / Right (or 4 / 6)	Run; on the map, the world before or after
Up, OK or EXE (or 8 / 5)	Jump (in Gravity: turn gravity round; in Flappy: flap)
Down (or 2)	Jump, in the room that says so
Up / Down on the map	The nearest world up or down
OK on the title and the map	Play
Any key, once dead	Try again
Back	Pause: Resume, Restart, Levels, Quit game
Home	Save and quit

Run to the door. These are the game's 80 rooms in its order: sixteen worlds of five (Pits, Spikes, Push, Coins, Controls, Platforms, Springs, Warps, Scale, Doors, Saws, Flappy, Gravity, Movement, Wraparound and the Boss), each with its own traps and timing, drawn with the game's own pictures. Clear a world's five rooms to open the next portal on the game's map. Your deaths are counted, with your best for each world. The game keeps a copy of its save in leveldevil_saves.py, so installing apps again doesn't erase your progress.

Jetpack Joyride

Key	What it does
OK (or EXE, Up), held	Fly; let go to fall
OK on a vehicle	What the vehicle does: jump, flap, flip gravity, teleport
Back	Pause (with Retry, How to play and Quit)

Barry runs through the lab by himself: hold OK to fire the jetpack and fly, let go to drop. Keep clear of the zappers, the lasers that charge up across the screen and the missiles that warn, lock on and fire. Grab coins, and the vehicle boxes for a ride that takes one hit. Spin tokens play the Final Spin when the run ends, where a Second Chance brings it back. Your best distance and coins are saved.

## Stickman Hook

Key	What it does
OK (or EXE), held	Hook onto the nearest hook; let go to fly
Arrows	Move in the menus
Back	Pause (with Restart, Levels, How to play and Quit)

Swing the stickman from hook to hook and over the finish line. Hold OK to grab the nearest hook and let go at the top of the swing to fly; bumpers throw you on, walls stop you, and falling off the bottom starts the level again. The first 39 levels are the game's own; after that every level is a new course made from the game's pieces. Reaching some levels opens new skins. Your level and skins are saved.

Donkey Kong

Key	What it does
Arrows (or 4, 6, 8, 2)	Walk, climb ladders
OK (or EXE)	Jump
Back	Pause (with New game, How to play and Quit)

Climb to the top and save Pauline, as in the 1981 arcade game. Jump over Kong's barrels for points, or grab a hammer (in mid-jump) and smash them. Four boards: the girders, the pie factory, the elevators and the rivets, where pulling out all eight rivets brings Kong down. Watch the bonus timer: it's your points if you finish and your life if it runs out. An extra life comes at 7,000 points. Home saves your game, and your best score is kept.

Dune

Key	What it does
OK (or EXE, shift), held	Speed up downhill and dive in the air
Back	Pause (with Restart, Shop, How to play and Quit)

The ball rolls on by itself. Hold OK going downhill to speed up and let go going uphill to take off. Fly over the line for points, and land on a downslope for a Perfect Slide. Land on your head, or on the uphill, and the run is over. Coins buy new balls and landscapes in the shop. Your best score, coins and shop are saved.

Monkey Mart

Key	What it does
Arrows	Walk
OK	Upgrades
shift	Hats
Back	Menu (with How to play and Quit)

Walk the monkey over the plants and animals to pick up what they make, carry it to the shelves, and take the money at the counter. Stand on a price pad to pay for a new stand, a machine or a worker; plants and animals get tired and need a visit to wake up. When the first mart is full, the truck takes you to the second. Your mart is saved.

Tomb of the Mask

Key	What it does
Arrows	Dash until you hit a wall
OK	Use a shield
Back	Pause (with Restart, How to play and Quit)

Dash up the tomb ahead of the rising flood, picking up dots and coins and dodging spikes, bats and other traps. The arcade climb goes on forever; the 200 stages each have three stars to find. Coins buy powerups and masks. Your progress is saved.

UNO

Key	What it does
Left, Right	Pick a card
OK	Play it
Up	Draw
shift	Say UNO, or catch a bot that didn't
Back	Pause (with New game, How to play and Quit)

Match the top card by colour or number, or play a Wild. Skip, Reverse, Draw Two and Wild Draw Four work as in the official rules, and you can challenge a Wild Draw Four. Say UNO when you're down to one card. The first to empty their hand scores the others' cards; the first to 500 wins. Your game is saved.

Friday Night Funkin'

Key	What it does
Left, Down, Up, Right (or 7, 8, (, ))	Hit the arrows
OK	Choose
Back	Pause (with Restart, Options and Quit)

Press each arrow as it reaches the line at the top. Sick, Good, Bad and Shit depend on how close you are; misses cost health, and the song is lost when it runs out. Play the weeks in story mode or any song in freeplay. There's no sound: the characters and the camera keep the beat. Your scores are saved.

Turbo Rush

Key	What it does
Up	Accelerate
Down	Brake
Left, Right	Steer
OK	Nitro
+, -	Change gear (manual gearbox)
Back	Pause (with Restart race, How to play and Quit game)

Three laps against seven rivals. A bend pulls you outwards, more the faster you go, so brake before the sharp ones. The grass slows you, and trees, lamps and buildings stop you and damage the car. Races pay credits for the engine, tires, nitro and armor in the garage. Play one race, the six circuits as a Grand Prix, or Free Ride. Home saves the race, and Continue picks it up.

Angry Birds

Key	What it does
Up, Down	Aim the slingshot
Left, Right	Pull it back less or more
OK	Fire, then OK again for the bird's power
1	Call the Mighty Eagle
shift (hold)	Look at the pigs
Back	Pause (with Restart, Levels, How to play and Quit game)

Knock down the pigs' castles and pop every pig. Each bird has its own power: the yellow one speeds up, the blue one splits in three, the black one explodes, the white one drops an egg bomb and the green one turns back. Fewer birds used means more points and up to three stars. Your progress is saved.

Portal Returns

Key	What it does
Left / Right	Run
Up	Jump
1 to 9 (not 5)	Fire a portal that way: 7 is up left, 3 is down right
5	Switch the color of the next portal
OK or EXE	Pick up or drop a cube, continue
Back	Pause

Help on the title screen shows every key and every test element.

Tetris

Key	What it does
Left / Right (or 4 / 6)	Move
Down (or 2)	Soft drop
Up (or 8)	Hard drop
OK	Rotate

EXE	After a crash, play again at once
Back	Pause menu (with Quit game)

Chrome's game when you're offline, as Chrome plays it. Run as far as you can: jump the cacti and the low pterodactyls, duck under the ones flying at head height. You go faster and faster, and every 700 points night falls for a while. Your best score is kept.

OK	Shoot
Back	Menu (with How to play and Quit)

He jumps by himself whenever he lands: steer him from platform to platform, as high as you can. Off one side of the page he comes back on the other. Green platforms stay, blue ones slide, brown ones break under him, white ones are gone after one jump and yellow ones blow up. Springs, trampolines, propeller hats and jetpacks throw him higher.

Key	What it does
OK (or EXE, Up)	Flap
Back	Menu (with Balls, How to play and Quit)

Going in without touching the rim is a swish: a basket is worth 1, a swish 2, and every swish in a row one more, with the ball on fire from the second. Six balls unlock with the original's goals. Your run, best score and balls are saved.
