Shikaku Twist: The Rectangle Logic Puzzle with Extra Clues 6×6 · 10×10 · 12×12 · 20×20 · 30×30 and 5 clue types Shikaku Twist is a logic puzzle based on Shikaku, the classic Japanese grid puzzle also known as Rectangles or Divide by Box. If you love Shikaku puzzles and want to put your spatial reasoning to the test, Shikaku Twist is the rectangle puzzle for you. Your goal: Divide the grid into rectangles and squares so that each of them contains exactly one numbered clue matching its area. The twist: Each clue also tells you what kind of rectangle to draw: Square, wide, tall, free, or any. How to Play Shikaku Twist: 1. Every clue has a number. It tells you how many cells your rectangle must cover. 2. Drag across the grid to draw a rectangle. To undo one, tap it. 3. Tile the entire grid so that every cell belongs to exactly one rectangle. No empty cells, no overlapping. The Five Clue Types: ◾ Square: Equal width and height. ◾ Wide: Width exceeds height. ◾ Tall: Height exceeds width. ◾ Free: Any proportion, but the cell count is fixed. ◾ Any: No restrictions. These five clues are what make each grid puzzle different. Features: • Daily Challenges: A new logic puzzle every day. Keep your streak going. • Multiple Board Sizes: From small 6×6 grids to large 20×20 boards, plus 10×10, 12×12 and more.
