Hashcash Chess
Welcome, -> Rating:
You need to win by checkmate. Timing the bot out does not give you any HCC rewards."Impossible" level is near impossible is more considered a donation option for those who want to support the site rather than an actual winnable difficulty level :)
Note: you can play 1 game per hour. Playing against higher level AIs costs more HCC but also rewards more HCC if you win.
Send the amount of HCC required (see cost per ai level) for the game to our Hashcash wallet address: 995c85982fd47fd7cbfec267545a8cb351b71ee5 after clicking "Find Game".
