Set a target time. Tap the buzzer to start a timer you can't see. Tap again to stop it. How close did you get?
Buzzer Challenge strips a timing game down to the one thing that matters: your sense of time, with no numbers to lean on while the clock runs. Play solo against your own best runs, or challenge your friends in local multiplayer mode by passing the phone around.
A blind reflex-timing game — start a timer, stop it, see how close you get
