More than 100,000 nonograms, from quick 10×10 puzzles to giant 100×100 ones. Play at your own pace, with no timers and no limits: every puzzle is a hidden picture you reveal cell by cell. Nonograms (also known as Picross, Griddlers, Hanjie, Japanese crosswords or Paint by Numbers) are logic puzzles where a picture is hidden instead of words. Every puzzle in JCross has exactly one solution, and you can reach it with pure logic, no guessing. HOW TO PLAY The numbers on the left and at the top give the lengths of the blocks of filled cells in each row and column. Blocks are separated by at least one empty cell and appear in the same order as the numbers. Fill the cells you are sure about, mark the ones that must stay empty with a cross, and the picture will appear step by step. FEATURES • More than 100,000 black-and-white nonograms grouped by size: from a two-minute warm-up to large canvases for several evenings. • Hints: stuck? The game shows your mistakes or the next cells that follow by logic. • Pinch to zoom and pan, so even 100×100 puzzles are comfortable to solve. • Undo (up to 100 moves). • Automatic crosses and clue marks: less routine, more logic. • More than 20 color themes, light and dark. • Portrait and landscape, iPhone and iPad. • Share a solved puzzle as a picture, a link or a QR code. • Game Center leaderboards and achievements. • Your progress is saved to the cloud and synced across your devices.
