How to play Colour Clash

A sealed-colour duel: one colour is sealed behind a cryptographic hash before anyone guesses, then revealed when the duel settles.

Setup

The creator seals a colour and a stake; the hash is published before an opponent joins.

On your turn

• The joiner calls a colour.
• The seal is opened and anyone can check it matches the published hash.

Winning, draws and losing

• The right call wins the pot minus the fee.

Online rules and fair play

• The seal is published before the guess, so the result cannot be changed afterwards — and you can verify it yourself.
