Reaction Tap Duel is the purest test of nerve: wait for the signal, then strike before your rival blinks.

Free 2-Player game · play on one screen

How to play

1. Sit two players at one keyboard (or one phone) — this is a local, same-screen game.
2. Player 1 taps the A key the instant the screen turns green.
3. Player 2 taps the L key the instant the screen turns green.
4. Hit your key the moment the screen turns green — never before.
5. Each player taps their own half the moment it flashes green.
