What’s new

Version 3.1.8G · Updated November 10, 2025

- improved the auto scrolling when submitting a new guess. Automatically going to the last played page when selecting a board to play. - added colorblind mode, and completely remade the game to make it much lighter/faster, if you have any issues let me know at [email protected] . Also if you have any improvement suggestions let me know also. Thanks.

Enjoy playing this game. A good way to get the brain working. I do think the hardest level could be called something different to "insane" as it seems wrong. Maybe "extremely hard" or something similar?
