About Prism Riot

Prism Riot is an original card game made by Dixon App Studio. It started as a mobile app for Android and iPhone and now plays in any browser at mindskillsarcade.com/crazy-eights too — the same 65 modes on both, with your web and app progress kept separately on each device.

The game runs entirely on your device. There are no accounts and no servers holding your progress — your level, streak and badges live in your browser's storage. Use the backup in Settings to move them.

Common questions are answered in the FAQ, recent changes are in the devlog, and writers and directories can grab screenshots and a fact sheet from the press kit.
