Bitcoin Chess

I made a game of chess where all moves are embedded into bitcoin transactions. Check out a video demo here:

It's not actually meant for real gameplay, it's just an educational resource to teach bitcoin developers and other interested people how key tweaking works. Basically if you learn how to embed chess moves into bitcoin pubkeys, you can embed more useful stuff too.

Play the game and read the code here: https://github.com/supertestnet/bitcoin-chess/
