Gambonanza

Gambonanza is a turn-based chess roguelike from Blukulélé where the board is small (often just 4×4 or 5×5) but every piece, square, and rule can be subverted with Gambits — modifiers you collect mid-run that bend traditional chess into something else entirely. Knights that explode on capture, pawns that promote on row two, kings that resurrect once per match. You build your run by stacking these modifiers; the boss fights at the end of each chapter test whether your particular combination of nonsense actually works.

It's chess for people who don't really like chess — the actual algorithm of "look ahead three moves" is replaced with "what does my current build of weird interactions do on this specific board." Released May 1, 2026; this download is build 23029088 (the launch build with day-one patches included).
