Nonograms Puzzle

Nonograms — also known as Picross, Griddlers or Hanjie — are logic puzzles where numbers turn into pictures. Every row and column carries a set of clues. Work out which squares are filled and which are empty, and a picture appears line by line.

No guessing is ever needed. Every puzzle has exactly one solution and can be reached by pure logic.

HOW TO PLAY
• The numbers next to a row or column tell you the lengths of the filled blocks, in order.
• Tap to fill a square, switch to the cross tool to mark squares you know are empty.
• Marking empty squares is the whole trick — it is what turns a wall of numbers into a solvable puzzle.
• A short interactive tutorial walks you through your first grid.

WHAT IS INSIDE
• Three grid sizes: 5x5 to warm up, 10x10 for a coffee break, 15x15 when you want to sit down with it properly.
• Hundreds of hand-checked puzzles, each with a single logical solution.
• Classic and standard field rules — pick the input scheme you are used to.
• Mistake counter with lives, and hints when a grid refuses to open up.
• Your progress is saved automatically. Close the game mid-puzzle and come back to the same board.

MADE FOR CALM PLAY
• Works fully offline. No account, no sign-up, no timer counting down on you.
• No energy bars and no waiting to play the next puzzle.
• Clean, quiet interface that stays out of the way of the grid.

Nonograms train the kind of attention that crosswords and sudoku do — but the reward at the end is a picture, not a filled table. Good for a few minutes in a queue and just as good for an evening.
