Prismagram

Every puzzle solvable by pure logic — no guessing, ever

What it is

Prismagram is a nonogram (picture-cross) puzzle game built around one promise: every puzzle is solvable by pure logic. No guessing, ever. Play 100 deterministically generated puzzles as short roguelite runs — keep your lives, earn perks, and push deeper. Crisp haptics, springy animations, and a high-contrast board make every filled cell feel great on iPhone and iPad.

One promise: no guessing

Every Prismagram puzzle is generated to be solvable by pure logic — each cell can be determined from the clues alone. No guessing, no trial and error, no reading the creator's mind.

Short runs, real stakes

Puzzles play out as roguelite runs: you have lives, solving earns perks, and streaks reward momentum. Each run is short enough for a commute but deep enough to chase a new best.

Built to feel good

The board runs at a silky 60fps with crisp haptics and springy animations. A high-contrast design keeps filled and empty cells obvious at a glance, in portrait or landscape, on iPhone and iPad.

All on-device

Prismagram stores everything on your device. No account, no ads, no tracking.
