Reaction Duel
Wait for green — fastest tap wins.
About Reaction Duel
Reaction Duel is a head-to-head reflex test for two players sharing one screen. The screen splits in half — one player each — and both sides sit red while you wait. The instant they flash green, slap your half: whoever taps first takes the round. But jump the gun and tap while it is still red, and you hand the round to your opponent, so it is nerve against nerve. First to three rounds wins. It is tense, twitchy, and over in seconds — perfect for settling an argument. Local two-player, fully offline, free and instant on any touchscreen.
