Play Reaction LightsA few ways to improve
- Wait until the light actually says GO. Anticipating it can count as an early tap.
- Reset your attention during the waiting phase of each new reaction trial.
Difficulty and daily progress
A round lasts 30 seconds. Every three starts of Reaction Lights raise its daily difficulty, up to difficulty 10. Your count resets at 00:00 UTC, so tomorrow begins with the starting challenge again. The clock continues if you switch tabs, and leaving ends the attempt.
Scores and rewards
The score measures this game’s performance. Reward points are a separate account balance. Practice rounds earn no points or XP and do not enter the rewarded leaderboard. Rewarded rounds require sign-in, human verification, active play, and live gameplay checks before a result is saved. Idle or abandoned rounds do not earn rewards.
Account points currently unlock site cosmetics. Each player level after level 1 adds a 0.1% bonus to points earned from games. Nothing is awarded for viewing or clicking advertisements. Read the fair-play rules or visit Support if a round needs help.
