OXYONWhat it is
Spades, with the outcome of each trick committed as a proof. The game is playable now; the proofs are what make a result reviewable after the fact.

CryptoSpades
Proof of Trick.
AlphaA card game on XL1
A card game whose hands settle as signed proofs on XYO's Layer One, so the result of a trick is something anyone can check rather than something you have to be told.
How it fits
A hand that settles on-chain needs no referee.
Why on XL1
The same reason the producers publish what they measure: a claim you can check beats a claim you are asked to accept.
With GeoHackers
CryptoSpades is one of the things the GeoHackers bot hosts. Payouts go to a wallet you have proven you control, which is what Verify is for.
The game lives at cryptospades.netlify.app and is in alpha. This page describes it and links to it; it does not host it. When the game moves here, this page becomes the game rather than a pointer to it.
