Puzzle-Nonograms. com is an online destination for playing Nonograms, also known as Hanjie or Paint by Numbers. The site introduces the logic puzzle through clear rules: players use numbered clues beside rows and above columns to determine which grid squares should be filled in black, marking other squares with an X.

The puzzles range from 5x5 to 25x25 grids, with additional special daily, weekly, and monthly challenges. Players can start a new puzzle, save or share progress, print puzzles, and use features such as checkpoints, a cell counter, coordinates, and highlighting for rows, columns, and completed lines. The game can be adjusted with options including night mode, left-handed controls, and a personal timer.

The site also offers a video tutorial, puzzle-specific help, an FAQ, statistics, a Hall of Fame, and mass printing. Beyond Nonograms, its collection includes many other logic puzzles, such as Sudoku, Kakuro, Binairo, Slitherlink, Minesweeper, and Battleships.
