Shikaku

Shikaku brings the classic Japanese logic puzzle to your device, offering a relaxing yet challenging brain workout for players who enjoy Sudoku, Nonograms or Minesweeper-style thinking. In each level you are given a numbered grid and must divide it into rectangles and squares so every shape contains exactly one number and the area of that shape equals the number inside it. The rules are simple to learn but the puzzles scale in difficulty, making Shikaku perfect for quick daily play or longer sessions where focus and deduction matter without timers or pressure.
