RC Helper is an open-source Chrome extension developed for the RollerCoin platform, providing game automation and power collection convenience (RollerCoin Helper & Bot). It does not play the games robotically for you — instead, it automatically selects and starts the most suitable game on the game selection screen, and automatically harvests your power (Gain Power) when the game is over.
This tool acts as a safe RollerCoin assistant, auto game selector, automatic power collector (auto collect), and smart break reminder.
⚠️ Important: RC Helper is not a cheat or hack tool. It only automates the game selection and collection processes to save you time and does not violate RollerCoin rules.

The game I passed is still being selected. The jump list is automatically cleared after 10 minutes.Use "Always Skip" if you don't want it to be selected before time runs out.
The break screen opens too often/less often. Increase or decrease game time from the Popup → Break Settings card.

Technical highlights:
- URL traversal tracker (
checkGameTransitions) — the counter increments when the game ends, not when it starts;so that there are no false-positives in unsuccessful attempts - Hourly forecast based on EMA (Exponential Moving Average) — weighted average of the last 20 games, taking into account break times
- 4-mask spotlight system — tutorial overlay works correctly at any resolution with
position:absolute+ scroll-aware coordinate calculation - Update protection — Version comparison from GitHub Releases API, auto-play blocking on old version
- Zero dependencies — all UI vanilla JS + inline/external CSS, no npm packages
- Manifest v3 + Service Worker architecture
