Griddlers Online

Griddlers is the name many puzzle magazines use for nonograms. If you grew up solving them on paper, this page gives you the same puzzle on screen, starting with a 15×15 grid for a satisfying, longer solve.

Unlike paper, the game checks your progress and our solver guarantees every puzzle is solvable by logic alone.

Classic griddler techniques

  • Overlap: in any line, cells covered by a block in every possible position must be filled.
  • Edges: a filled cell at the edge starts or ends the first or last block.
  • Completed lines: once a line's clues are satisfied, mark the rest as empty.
  • Joining: two filled cells that must belong to one block can be connected.

Paper vs online

On paper you need an eraser for mistakes; here you can toggle cells freely and mark empties with X. Your times are tracked, so you can see your solving speed improve.
