Recto: Shikaku Logic Puzzle

Recto — also known as Patches — is a calm, relaxing Shikaku puzzle game, the classic Japanese logic puzzle also known as "rectangle division" or Sikaku. Every grid is scattered with numbered clues: draw rectangles so each one contains exactly one number, and its area matches that number. Cover the whole board with clean rectangular patches and the puzzle is solved.

If you love Sudoku, Nonogram (Picross), Kakuro, or other number and logic puzzles, Shikaku will feel instantly familiar — easy to learn in seconds, deeply satisfying to master.
