Can you beat quantum physics?
Guess quantum measurement outcomes and compete against an AI powered by real entanglement data from IBM's quantum processor.
No physics background required. Play single-player or multiplayer, climb the leaderboards, and pick up the actual ideas behind Bell inequalities and entanglement along the way.



Real data. Real physics. Actually fun.
Real quantum data
Game outcomes are driven by real measurements from IBM's Marrakesh quantum processor.
Meet Alice
The AI opponent uses quantum advantage to beat you over the long run, but you'll have your moments.
