Fact Sheet

LogiSketch is a premium nonogram puzzle app for iPhone, iPad, and Mac (also known as Picross, Griddlers, or Hanjie). Every puzzle is analyzed by a solving engine and rated by the actual logical reasoning required to solve it, Intuitive, Logical, or Analytical, instead of by grid size the way most nonogram apps do.

Puzzles range from small, quick grids to gigantic works up to 90 cells wide, solvable as one whole puzzle or broken into manageable panels. Advanced Marks give serious solvers two more tools: color-exclusion marks rule a candidate color out of a cell and auto-fill it once only one remains, and Q-mark conjecture sets let you stack up to four "what if" guesses and prove or disprove a whole level at once. Expert gestures (pinch-to-select, swipe-fill, row and column locking) speed up play for veteran players.

No ads, no subscriptions, and nothing forced on players just to keep playing: a free Starter gallery is included, and more than 25 additional themed galleries are one-time purchases, every one of them family-shareable. Progress follows your iCloud account across iPhone, iPad, and Mac. Works fully offline.

LogiSketch is developed by Steven H. VanderLeest at squishLogic, an independent studio. Version 1.0 released August 2026; version 2.0 added iCloud sync and a native Mac app; version 2.1 adds Advanced Marks (color-exclusion marks, Q-mark conjecture sets, Color Focus) and a guided in-app tour for them; version 2.3 adds the reverse conjecture (flip your first guess, and any cell that comes out the same both ways is proven and filled in on black and white puzzles) and has auto-play name each deduction it makes.
