Why It's Different?
Never a Guess
Every level is verified by an algorithm we wrote before it ships. A level with more than one solution, or one that needs guessing, never makes it in.
Measured Difficulty
Levels are ordered not by size alone (10x10, 15x15) but by how many steps of reasoning the solution actually takes.
Ads on Demand
No interstitial ads interrupting play. You only watch one when you choose to, for a hint.
No Account Needed
No sign-up, no login. Your progress stays safely on your own device, and you can play offline anywhere.
IN THE NEXT MAJOR UPDATE
What's Coming
The modes below aren't released yet — they're still in the works. The version you can download today contains the classic nonogram levels.
Colour Puzzles
The clue numbers become coloured, and a number's colour is the colour of its group. Two groups of the same colour need a gap, while different colours may touch. When colours are hard to tell apart, each one can carry its own shape, so the puzzle stays solvable from the symbols alone.
Big Pictures
A large picture is divided into nine pieces. Each piece is a puzzle in its own right and can be solved in any order; as the pieces are completed, the whole picture appears.
Daily Puzzle
One puzzle opens each day, the same one for every player. Solving it extends your streak by a day; a missed day resets it.
Zen Mode
Mistakes aren't counted, the board never locks and nothing is timed. A level can be played through at your own pace. In return, zen mode awards no stars.
Choose Your Difficulty
Every picture can be opened as easy, medium or hard; the difference is how many mistakes you're allowed. On easy the allowance grows with the board, and hard is played with two.
Make Your Own
You draw on an empty board and the game checks it: a puzzle counts as fair when it can be solved without guessing. Fair puzzles get a share code, and a friend can solve the very same puzzle from it.
