Show HN: Chess on a Donut/Torus and Deep-Dive
mchess.ioHey there! I just finished a youtube video explaining our donut chess in detail: https://youtu.be/iRcfHCPFgkM
So I thought it'd be cool to show it off here too- it can be played around with at mchess.io/donut - you can also set up an AI or online game on the site.
This is all indie dev work from a couple friends and myself.
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)
that'd be a fun puzzle!

interesting puzzle collection :)
My favorite torus game is Tetris on a Torus

very neat. I'd say this is kinda on top of a torus, and more of a cylinder from the perspective of the Tetris pieces. not sure how you'd play on the surface of a torus, since you need to wrap around vertically too.
E.g the pieces from the rows you eliminate reappear at random at the top row.
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
hmmm good idea, maybe we should have an auto-rotate that stops when you interact
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
ahha true, I forgot this was the case. we like the setup this way as it has rotational symmetry, which more naturally extends to supporting 3+ players
