Click on a puzzle to open it in a new window. Pieces that fit together will click into place, while incorrectly fitting pieces will not. Watch the clock and see how fast you can complete each puzzle! Once you're done, use the "Change Cut" option on the left to change the size and number of the pieces and start again. Good luck and have fun!
