Griddle – picture logic puzzle game

Griddle is a picture logic puzzle game for Linux. It offers a graphical implementation of nonograms, also known as Picross or Griddlers, in which players uncover a hidden picture by determining which cells in a rectangular grid should be filled.

Each row and column has numerical clues indicating the lengths of consecutive groups of filled cells. The challenge is to work out how these groups fit together, using logical deduction to identify the correct pattern.

The game has a straightforward graphical interface with mouse and touchscreen controls. It is designed for players who enjoy solving number-based puzzles without time pressure or complicated game mechanics.

This is free and open source software.
