Nonograms Puzzle

Nonograms are logic puzzles where numbers turn into pictures. Each number tells you how many squares in a row or column to fill — work out the rest, and the hidden image appears.

Three sizes, three levels of challenge:
• 5×5 to learn the rules
• 10×10 for a short break
• 15×15 when you want to think

Features:
• Classic and Standard modes — play freely, or with a limit on mistakes
• Hints when a puzzle stalls
• Coloring mode and cross marks to track what you have ruled out
• Undo for a wrong tap
• Progress saved automatically — close the app and come back later
• Plays offline

No timers, no pressure. Just you and the grid.
