Show HN: Chess on a Donut/Torus and Deep-Dive (mchess.io)

It's fun to sit down and draw what the board looks like when you cut and flatten the torus before you watch the video!

Bonus points if you hit upon the other 2D projection that is useful (I didn't)

looks like the white king/queen aren't on the right colors (queen goes on her color) - confused me a bit when trying to map the space to a 2d board

Shameless plug. If you're into chess-themed puzzles, you might like: https://chedoku.com/blog/chessPuzzles

Took me a while to realize it was a 3D torus and I had to drag around to see the whole board lol

Maybe when the page loads the torus should rotate around a bit

My favorite torus game is Tetris on a Torus

Thanks for sharing!

Rotating the torus eventually hits singularities and I cannot continue the rotation. Maybe use a different mechanism for rotations that do not suffer from "gimbal lock"?

Would also be nice to rotate the torus along the circular axis. That is, rotate pieces/rows from inside the doughnut hole to the outside.
