🎴 CryptoSpades

Proof of Trick — 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.

♠️ What 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.

🔗 Why on XL1

A hand that settles on-chain does not need a referee. The same reason the producer pages on this site publish what they measure: a claim you can check beats a claim you are asked to accept.

🤖 With the bot

CryptoSpades is one of the things the GeoHackers Discord 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 under winlew.co/xl1 this page becomes the game rather than a pointer to it.
