Nonogram
Nonogram (also called Picross or Griddlers) is a classic logic puzzle where you paint cells in a grid to reveal a hidden picture. Each row and column has number clues that tell you how many consecutive filled cells appear in that line — your job is to deduce exactly which cells to fill. This version features 5 difficulty levels: Beginner (5×5), Easy (7×7), Medium (10×10), Hard (12×12), and Expert (15×15). Each level has multiple hand-crafted puzzles to keep things fresh. Race against the clock — the faster you solve, the higher your score!
How to Play Nonogram
Each row and column shows number clues on the side and top. A clue like "3 2" means there is a group of 3 filled cells, then a gap, then a group of 2 filled cells, in that order. Left-click (or tap) a cell to fill it black. Right-click (or long-press on mobile) to mark a cell with ✕ as a reminder that it must be empty. Fill in all the correct cells to solve the puzzle!
Nonogram Tips & Tricks
Start with rows or columns that have the largest clue numbers — these constrain the most cells. If a clue number equals the row length, fill the entire row. Use ✕ marks liberally to rule out cells you know are empty. Work back and forth between rows and columns, using each new cell you fill to update your knowledge of intersecting lines.
