Patches: The Ultimate Rectangle Logic Puzzle - inspired by Shikaku
6×6 · 10×10 · 12×12 · 20×20 · 30×30 and 5 different shapes!
Dive into Patches, the addictive logic puzzle based on Shikaku, the classic Japanese grid-dividing game - also known as Rectangles or Divide by Box. If you love Shikaku puzzles and want to put your spatial reasoning to the test, Patches is the perfect rectangle logic puzzle for you!
Your goal: Partition the grid into rectangles and squares so that each shape contains exactly one numbered clue matching its area. The unique twist: Each clue also tells you the shape direction: Square, wide, tall, free, or any!
How to Play Patches:
1. Every cell contains a shape icon and a number. The number indicates how many cells your rectangle must span.
2. Draw rectangles by dragging across the grid. A valid selection appears in orange; an invalid one turns red. To undo a rectangle, simply tap it.
3. Your goal is to tile the entire grid so that every cell belongs to exactly one rectangle. No empty cells, no overlapping.
The Five Shape 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 whatsoever.
These five constraints are what give every puzzle its distinct challenge.
