About this game

Nonogram: Pure Logic Puzzle is a clean, lightweight nonogram game built for players who want the puzzle - nothing else.

Nonograms are logic grid puzzles solved entirely by deduction. No guessing. No pictures to reveal. Just pure, satisfying logic from first clue to last cell.

A million levels. Always more to solve.
With over 1,000,000 procedurally generated puzzles across a range of grid sizes and difficulties, you will never run out of challenges. Every puzzle is unique, and every solve is earned.

No forced ads. Ever.
No interruptions mid-solve. No ads between every level. Play at your own pace, the way puzzle games should work.

Classic Mode
The nonogram experience you know: pick a size, pick a difficulty, and solve. Straightforward, focused, and always available offline.

Rogue Mode
A new take on nonograms. Face a gauntlet of puzzles with active modifiers that change the rules as you go. How far can you get?

Make it yours.
Customize the grid colors, UI theme, and visual style to suit how you like to play. Cosmetic options are unlocked through play or optional purchase - your call.

Helpful tools when you need them.
Bonus tools are available to help work through tough spots, earned through play or available via optional purchase.

Play anywhere.
Fully offline. No internet connection required, ever.

Tablet users! Check out ""Scale"" in the settings!

A few things to know before you download:
Puzzles are procedurally generated and do not produce pictures or pixel art on completion. If you are looking for picture-reveal nonograms, this may not be the right fit. If you want pure logic puzzles with no filler, welcome home.
