Fischer Increment Chess Clock
Professional Fischer increment timer — each player gains extra seconds after every move. Perfect for blitz, rapid, and classical chess games.
How Fischer Increment Works
Before Your Move
Your clock counts down from your remaining time. You must complete your move before time runs out.
Make Your Move
After you move a piece and press the clock, the increment (bonus seconds) is immediately added to your remaining time.
Time is Added
With Fischer increment, your time can increase beyond the starting amount if you move quickly. This rewards fast, accurate play.
Never Lose on Time
Fischer increment ensures a player always has meaningful time to play accurately, making games fairer and more competitive.
