Choose a game

The game starts by choosing One Player, Two Players, or Multiple Players mode. The number appearing on the Multiple Players mode icon shows how many players are waiting to play. In One Player mode you can practice alone in one of the following ways: Practice, Beginner, Intermediate, and Professional. You will receive a notification if someone is waiting for an opponent to play with.

The program generates a random number between 3 and 10 seconds to the accuracy of one-hundredth of a second or a millisecond that will be displayed on the green stopwatch. The goal is to stop the counter as close as possible to this number by clicking the red STOP button.

Have fun!
