Shikaku Cafe: Logic Puzzle

Shikaku Cafe is a calm logic puzzle and brain game built on Shikaku, the classic Japanese number puzzle. You divide the grid into rectangles. Each rectangle holds one number, and that number equals its area.

You play at your own pace. The game has no timer, so you can think over a move with a coffee in hand. Fans of sudoku and nonograms will know the feeling of a board that clicks into place after a chain of deductions.

The campaign has 200 handcrafted Shikaku puzzles across 8 chapters. It starts with small 8x8 grids and builds toward boards that test every trick you have learned. For a short break, pick Beginner, Standard or Expert and get a fresh number puzzle in seconds.

Want something bigger? Set any grid size from 8x8 to 40x40. Zoom keeps the large boards easy to read.

Twist mode keeps the Shikaku rules and changes the boards. Some numbers hide behind question marks, and you work them out from the rest of the grid. Other boards come in unusual shapes.

You earn points as you solve and spend them on skins for your rectangles and the cafe interface. You get a gift every day, hints help when a logic puzzle stalls, and your stats show how far you have come. Solve a few grids on your coffee break and give your brain a workout.

Coffee Mode removes ads if you prefer to play without them.
