Grid Patch - Shikaku Puzzle

Grid Patch - shikaku is a relaxing geomertical logic puzzle where every clue is a rule. Draw patches around numbered clues and cover the whole grid. Each patch must match its required area and allowed shape. Patches cannot overlap, no cell can be left empty, and every campaign puzzle has one valid solution. Solve by logical thinking — not guessing. A FRESH TWIST ON RECTANGLE PUZZLES Classic rectangle puzzles tell you the size. Grid Patch also uses shape clues.
