Using the clock
Tap your own side after you move; your opponent’s clock starts. The top clock is rotated for the player opposite (switch off in settings). In multi-stage controls, extra time is added to a player when they complete the stage’s move count. Once this page has loaded it works without internet, and it asks your device to keep the screen on during a game.
