Nonograms Online
Nonograms (Picross) are logic puzzles where you fill in grid cells using number clues to reveal a hidden picture. Free online and endlessly satisfying.
About This Game
Nonograms are logic puzzles that combine deduction with pixel art. Each puzzle presents a grid with number clues along the rows and columns. These numbers tell you how many consecutive filled cells appear in that row or column, and your job is to figure out exactly which cells to fill. When you solve the puzzle correctly, the filled cells reveal a hidden picture.
The appeal of nonograms lies in the pure logic satisfaction. Unlike crosswords or trivia, nonograms require no outside knowledge — everything you need to solve the puzzle is in the numbers. Each cell can be deduced through logical elimination, making that moment of certainty when you fill in a cell deeply rewarding. The puzzles range from simple 5x5 grids to massive 25x25 or larger challenges that take hours to complete.
Online nonogram platforms offer thousands of free puzzles in various sizes and difficulties. Most include helpful features like error checking, undo history, and cell marking (X for cells you've determined are empty). The community around nonograms is passionate, with players creating and sharing custom puzzles. For anyone who enjoys Sudoku or logic puzzles, nonograms offer a visually rewarding alternative that produces a tiny piece of art with every completed puzzle.
How to Play
Read the number clues
Numbers along each row and column indicate groups of consecutive filled cells. For example, "3 2" means a group of 3 filled cells, at least one gap, then a group of 2.
Start with the largest clues
Rows or columns where the numbers add up close to the total grid size have cells that must be filled regardless of position.
Mark empty cells
Use X marks to indicate cells you have determined are empty. This helps narrow down remaining possibilities.
Use cross-referencing
Information from one row or column can help solve intersecting rows or columns. Work back and forth until the picture is revealed.
Tips & Strategy
- Always start with rows and columns that have the largest clue numbers relative to the grid size.
- Mark empty cells with an X — knowing where cells are empty is just as important as knowing where they are filled.
- Use the "overlap" technique: if a clue of 7 exists in a 10-cell row, the middle 4 cells must be filled regardless.
- Work systematically rather than jumping around. Complete what you can in each row before moving on.
