🧩 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:
Each clue's icon tells you how your rectangle must be shaped:
◾ 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.

User Reviews
Just watched a full length ad (~30s) to even be allowed to start the daily puzzle, which took exactly 14 seconds and was followed up with another full length ad. So i spend 4x as much time watching ads as i did playing. So, yeah... done with this. And yeah, you get to play three games for each ad you watch, but the last two daylies were 29s and 18s, so it's still barely half game and half ad.
I absolutely adore this app, along with Rumba they are my two favourite apps on my phone. I love the challenges they provide and that it's not always obvious. But I have a question, who should I contact when a pack I got from 3 friends redeem doesn't appear after a while? (longer than 24h)
Its a good game with few ads. It is easy to understand and while I do think it is a bit annoying that a big part of the puzzles are locked behind a pay wall I will just play what is free for now.
Display is not well optimized. Numbers are squares get partially cut off on larger puzzled even when fully zoomed out
