Binairo vs Prism

Binairo is a clean binary puzzle and 0-1 logic game for quick daily brain training. Fill the grid with zeros and ones, keep each row and column balanced, avoid triples, and solve by deduction instead of guessing. Play the daily challenge, continue through curated levels, use undo and hints when needed, and compare your times on Game Center leaderboards. The interface is calm, fast, and built with VoiceOver support for accessible play. Start with the free puzzles, then unlock the full premium library when you want more handcrafted binary grids.

One mirror setup. Two light states to solve. In Prism, turning a mirror changes two light routes at once. Switch between A and B, inspect what your adjustment changed, and find one arrangement that lights every target in both states. Helping one route can break the other. That is the puzzle. DUAL-LIGHT COMMISSIONS • A new daily commission is free to play. Take your time: no countdown or attempt limit. • Prism Pro adds a workbench with three difficulty levels, using 4, 6, or 8 shared mirrors, plus the previous 30 daily commissions. • Your light folio keeps up to 90 recent commissions on this device. Completed commissions still in the folio can be revisited without Pro. • Share a challenge code when you choose. A friend can enter it and play the same puzzle free, without an account or subscription. • Hints, undo, and restart are available while you work. Commission hints do not cost tickets or money.
