One simple rule: tap only when the light turns green. Only When Green turns a single tap into a test of patience, timing and precision. Wait through red and amber, react when GO appears, and build your streak as the pace picks up. Tap too early or let green slip away, and you lose a heart. - Classic mode: Start with three hearts and chase your personal best. - Daily challenge: Take on a fresh challenge each day and land 20 successful green taps. - Reaction records: Track your fastest reaction, average reaction time and best streak. - Guard protection: Six correct taps charge a Guard that covers one mistake. Three reactions under 300 milliseconds earn a free Guard and 75 bonus points. - Interactive tutorial: Learn green-light timing and Guard through hands-on practice in Signal School. - Colour collections: Earn XP through play and unlock new colour styles. - Play comfortably: Enjoy clear signal symbols, adjustable sound and haptics, and pause whenever you need a break. Wait for your moment. Make the green count. Contains advertising. Optional rewarded ads offer one extra-life continue per Classic run.
