About game
🧩 The Japanese puzzle Shikaku: numbers sit on a grid and the whole field must be cut into rectangles.
🎯 Each rectangle holds exactly one number, equal to the count of its cells.
✅ There is always a single solution — nothing is guessed, everything follows strictly.
💡 Start with the primes: a seven or a five fits only one way and carves off a strip at once.
📐 The rest unfolds from there, step by step, until the grid is done.
🏁 Levels run from a six by six field to large grids that take several minutes.
↩️ Made a mistake? Undo and try another cut — there is no penalty.
🎨 Several themes to choose from, from plain to bright.
☁️ Progress saves to the cloud and a daily goal waits for tomorrow.
❓ Can you finish a large grid without a single hint? 🔥
How to play
🎮 Drag a frame from cell to cell, or tap two opposite corners.
✅ Each rectangle must contain exactly one number.
🎯 That number equals the count of cells inside it.
📐 Rectangles never overlap and leave no empty cells.
🏁 The level is done when the whole field is covered.
↩️ Made a mistake? Undo the move or restart the level.
📱 On the phone just drag your finger across the cells!
