Nonogram and Logic Puzzle Methods

Learn a calm method for solving nonograms and other grid-based logic puzzles without guessing.

Mark certainty first

Fill only cells forced by the clues, then mark spaces that cannot contain a filled cell. Each certain mark narrows the next deduction.

Work between rows and columns so new information travels across the grid.

Avoid speculative chains

When a puzzle becomes unclear, return to the last certain deduction instead of building a long chain on an assumption.
