See how far you and your friends can get. • Tap the lights directly — the same traffic light shows the sequence and takes your answer • Haptic feedback on every tap, with a distinct buzz when you get it wrong, so you can feel your mistakes • Game Center leaderboard • Available in English, Japanese and Traditional Chinese
