Rotate the 3‑D cube, memorise the colours and match every pair across 50 levels. No downloads – works on mobile & desktop.
All games are free and open from the first visit. Mini-game progress is saved only in this browser, when storage is available.
On this device saves your best 10 Daily and Random runs automatically when you complete a level. These scores are available only in this browser; clearing site data removes them.
Global Top 10 shows scores shared by players. Daily today covers the current Daily challenge and resets at midnight UTC. All-time combines Daily and Random games, keeping each browser's best score while it remains in the top 10.
Choose a nickname in Scores to enable automatic sharing after future level clears, or use Submit to global scoreboard after completing a level. Only top-10 scores appear on the public board. Choosing a nickname does not publish your older local score history.
If a score cannot save while sharing is enabled, it stays on this device and retries when you reconnect or next open the game. Scores shows its saving status and a retry button. Stop sharing turns off automatic sharing and cancels pending uploads; it does not remove scores already published.
