Shikaku is a logic puzzle where you divide the grid into rectangles. Each rectangle must contain exactly one number, and that number tells you how many cells belong inside it. The goal is simple to understand, but solving each board takes planning and careful deduction.

Pick a board size, start solving, and use practice mode to build confidence at your own pace. Smaller boards are great for learning, while larger ones give you more room for deeper logic.

Start by looking for clue cells that have only a few realistic rectangle shapes. Small values often force quick decisions, and those early placements make the rest of the grid easier to read. If a clue seems too flexible, leave it for a moment and return after nearby rectangles are confirmed.

It also helps to think in terms of coverage and pressure. Ask which cells must belong to a certain clue, which spaces are becoming crowded, and which large rectangles are losing room to fit. Good Shikaku solving usually comes from patient elimination rather than speed alone.
