Free online Nonogram puzzles (also known as Picross or griddlers) with no ads and no sign-up. Pick a 5×5, 10×10, 15×15 or 20×20 grid or play the daily puzzle. Every puzzle is generated to be solvable by pure logic with exactly one solution, so you never have to guess. Fill and cross modes make it comfortable on a touch screen, with undo, a check button that shows wrong fills, auto-save on phone and desktop so you can pick up where you left off, and leaderboards for puzzles solved and the fastest 15×15 times. How to play: the numbers next to each row and above each column give the lengths of the runs of filled cells in that line, in order, with at least one empty cell between runs. Use the clues to work out which cells are filled; when the filled cells match every clue, the picture is complete.
