Start a game
Open the time controls using the sliders button. Choose a preset or set each player’s starting time, then tap New game. Tap the center clock or the active player’s clock to begin. White’s clock starts first.
Switch turns and pause
After your move, tap the center clock or your active clock to start your opponent’s time. Use Pause for a break and Resume to continue.
Increment or delay?
Increment adds time after each completed move. Delay gives each turn a grace period before time starts counting down. Choose one at a time in the time controls.
Why did the clock pause?
The clock pauses when you leave the app or lock the screen. Return to Clock Imperium and tap Resume to continue. The screen stays awake while the clock is running.
Reset or change the time
The reset arrow returns both clocks and move counts to their starting values. Applying time controls with New game also begins a fresh game.
Does it need an internet connection?
No. The chess clock works offline and does not require an account. Opening these support or privacy pages requires an internet connection.
