Quickdraw

Two silhouettes against a sunset. DRAW! appears at an unpredictable moment — tap and your reaction time is shown in milliseconds; tap too early and you lose the round. Best of three, then the next opponent up a ladder of ten, from Dusty Pete to El Sombra, each with their own fake-outs. A daily duel and win streaks keep you coming back. The game rules are built and tested; the iPhone app is next.
