Nonogram· Advanced

Goal

Fill in cells using number hints to reveal the hidden picture.

How to Play

  • Tap an empty cell to fill it
  • Tap a filled cell again to mark it X (confirmed empty)
  • Tap an X mark again to clear it back to empty

Keep Block Order Correct

Numbers represent consecutive filled blocks from left (or top). The order must match — swapping groups is wrong.

Gap Required Between Groups

When there are multiple numbers, at least one empty cell must separate each group. Merging groups is wrong.

Completed Example

  • Numbers indicate consecutive filled cells in that row/column.
  • Multiple numbers mean at least one empty cell between groups.
  • Use X marks to flag cells that are definitely empty.

Tip

  • Start with rows/columns that have the largest hints — more cells are guaranteed
  • Use X marks actively to avoid mistakes
  • Cross-check row and column clues together for easier solving

Nonograms combine spatial reasoning with logical thinking to train visuospatial processing. Grid-based puzzles have been shown to engage multiple cognitive abilities.
