Nonogram
Nonograms are logic puzzles that require constraint satisfaction and deductive reasoning. Participants fill in a grid using number clues that indicate how many consecutive cells are filled in each row and column. The task engages logical deduction, working memory, spatial reasoning, and planning.

Sample Instructions
"Fill in the grid using the number clues. Each number tells you how many consecutive cells are filled in that row or column. Tap a cell to fill it. Use the Mark button to flag cells you know are empty."
Usage
Grid sizes vary by difficulty: 5x5 (easy), 7x7 (medium), 10x10 (hard). Clues indicate consecutive filled-cell runs for each row and column. All puzzles are verified solvable by line logic alone (no guessing required). Incorrect fills flash red as immediate feedback. Correctly filled cells are permanent. A mark mode is available for flagging cells known to be empty.
Scoring
Puzzles are scored by completion and error count. A puzzle solved with zero errors is "solved perfectly."
