Shikaku: Divide by Box

Divide the Grid. Trust the Numbers. Find the Balance.

Every number hides a rectangle — and every rectangle must fit just right. Your task is simple to learn, devilishly hard to master: split the board into boxes so that each one contains exactly the number it shows.

What starts calmly soon turns into a deep logic challenge where every decision matters. One wrong cut can echo across the board, while the right insight makes everything click into place. No guessing, no luck — just pure reasoning, pattern-spotting, and patience.

With endless handcrafted puzzles, rising difficulty, and a progression system that rewards mastery, this is a game for players who enjoy thinking several steps ahead. The challenge grows sharper, the grids more demanding, and the satisfaction stronger with every solved level.

Clean design. Deep logic. Serious brain workout.

If you enjoy Sudoku — but wish it had more structure, more tension, and more “aha!” moments — this puzzle is waiting for you.

Think in rectangles. Divide with purpose. Solve them all.
