Show HN: Chess in Hyperbolic Space

https://mchess.io/hyperbolic

Heya I thought I'd post here again, after finishing up a big project. Press or tap WASD to move around the board, E will reset you to the center.This is a chess board built out of octagons, with 3 meeting neatly at a vertex- this isn't usually possible, but you can do it in 'hyperbolic space' which has curvature that essentially allows for more room around a point.I also have a video which...

Hey there! I just finished a youtube video explaining our donut chess in detail: https://youtu.be/iRcfHCPFgkMSo 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.

Show HN: Chess site with 30 combinable variants, including möbius chess

https://mchess.io

mchess.io (Meta-variant Chess) is an indie project friends and I developed some years back now. We've recently had motivation to introduce bot players and think it's in a state that's worth showing off to more people.I made a youtube short for what we're calling the beta release: https://youtube.com/shorts/r9GZ59pxEM0?si=7ZRz_bPScI0xYRra
