Logic adventure · iPhone
Bell's Grid
Eight cells agree. One glitch always escapes. Can you make it disappear?
Bell's Grid is a tactile, single-player-first logic adventure about two separated partners trying to keep one shared promise. Build a Promise Book, test every row-and-column meeting, and chase the Ninth Glitch as it moves around the 3×3 grid. Experience through play why classical logic stops at 8/9—and what changes when a quantum strategy reaches 9/9.

Highlights
Build a Promise
Write reusable responses into your Promise Book before the partners separate. Your AI partner follows the saved protocol exactly—no hidden tricks.
Chase the Ninth Glitch
Repair one contradiction and watch it reappear somewhere else. Every movement is evidence produced by your protocol, never a random loss.
From 8/9 to 9/9
A guided adventure for players ages 10 and up lets you reach the best classical result yourself before revealing how a quantum strategy changes what is possible.
