Breakout (small cells version). After I had discovered a quirk of Excel, for me the fun was over (I should redo it totally to fix it) so it certainly is not finished. It is all done with colored cells.
Mambo: someone told me about trying to make the game Mambo for Excel. I didnít know the game but made this based on the description in a few hours. Nothing special but still OK to play. Eat the balls before the countdown ends because then it will change into a wall.
