Hey HN! I'm sami, the creator of echo chess. This is the true story of diving way too deep into a rabbit hole of chess, ML, and puzzle design. Hope you enjoy the read.
Originally built this chess variant as a fun hack but it really escalated since then. It's a single-player puzzle game. You're playing white, there's no opponent, and you need to clear the board to win. Every time you capture a piece, you become the 'echo' of that piece.
There's also an 'endless' mode with infinite levels generated in real time and validated by ML to ensure solvability. Took forever to make it work but it now has 99% accuracy. You can play the 'classic' mode here: https://echochess.com/ and endless here: https://echochess.com/?endless
