How to play

Pick the computer's difficulty (easy, medium or hard) and the match length: best of 1, 3 or 5.
Tap I'm ready. The pad turns red - don't touch it yet.
After a random wait of a few seconds the pad turns green. Tap it as fast as you can.
The quicker reaction wins the round. Times are shown in milliseconds once both are in.
Tap while the pad is still red and it's a false start: you lose the round.
If neither of you gets a valid time, or it's a dead heat, the round is played again. First to win more than half the rounds takes the match.

Think you're quicker than your friends? Start a Reaction Duel room - each phone times its own player, so a slow connection can't cost you a round. Go to Play
