Chess clock

Digital chess clock with variable time limit and optional extra time per move

You have a chess board but no chess clock is at hand?

This simple function displays the remaining time for each player as well as the actual round. The currently active timer is indicated by its bold font.
You can set variable time limits per player and an optional extra time per move.
Press the space bar to switch the active timer.
Press Escape to pause or exit.

It will not give you the feeling of punching a real chess clock, but it may serve as a substitute if needed
- and my opponents usually insist to use one when playing with me...
