Free online jigsaw puzzle for adults and kids of a clock used during a chess game. The clock is used to ensure the game is not overly delayed by either player.
I learned how to play chess when I was very young. I didn't play often and eventually I forgot most of what I knew. I played Scrabble with my sister quite often. I wished we had one of those clocks so I could avoid a long wait for her to come up with a word.
