Grid Patch is a grid-based logic puzzle where you fill the entire board using patches — rectangular and square shapes. Each numbered tile on the grid tells you the exact size of the shape that must cover it. Your goal is to place every shape so the board is complete, with no gaps and no overlaps. Inspired by Shikaku and classic tiling puzzles, GridPatch brings a clean and modern patches-based approach to grid-based logic challenges. It sounds simple, but each puzzle demands careful observation, spatial reasoning, and logical deduction. Start from the numbers, work out which shapes fit, and piece together the solution step by step.
