User interface

Every page

On every page there is:

• Header:
  • Title which is a link to the main menu page
  • Language selection box that allows the user to change the language of the page without reloading

Main menu

Main menu is basically a form for creating a game.

Click on the multiplayer option will take the player to the multiplayer lobby.
Click on the back option will take the player to the previous step.

Creating a game is a 3-step form:

1. Enemy (AI or player on the same device) and game mode
2. Starting player and type of game (standard, reversed)
3. Board size, players marks, changing sides every game

Multiplayer lobby

The lobby shows all existing games in the form of a list of rooms that the player can join or create a new one. When there is no players in the room, the room is deleted. If the room is full player can't join until some place becomes available. In that case the join button is disabled. Rooms protected by password has a join button with a lock icon. After clicking it player has to put the correct password in order to join to the game.

Each of the rooms in the lobby has:

• Unique ID
• Name consisting of:
  • Mode
  • Players marks
  • Board size
  • Type of a game
• Number of players in the room
• Join button

Creating a game is similar to creating a game in the main menu. The difference is that it is packed in one form and has option for setting password.

Player has to choose:

• Game mode
• Board size
• Type (uncheck = standard, check = reversed)
• Password (empty = no password)
• Players marks
• Starting player
• Switching sides every game
