What did you predict? What changed? Which part of the game models quantum behavior—and where does the analogy end?
Serious ideas. Room to play.
These games connect quantum concepts to cards, coins, coordinates, and familiar arithmetic. Some use quantum calculations; others are teaching metaphors. The guides help you explain both the connection and its limits.
Developed and adapted using QCaMP classroom materials. Ghost Grid draws on Allan Goff’s quantum tic-tac-toe. Original credits are included with the games and guides.
