About game
Staring at a blank screen during your coffee break often feels like a waste of time. Japanese Puzzle: Shikaku turns that idle moment into a sharp mental workout that keeps your brain firing. You start with a grid containing various numbers scattered across the board. Your main job involves drawing rectangles that cover specific areas until the entire board is full. Every rectangle must contain exactly one number, and the size of your shape needs to match the digit inside. Navigating these constraints requires careful planning since your shapes cannot overlap or leave empty gaps. This shikaku puzzle provides a steady challenge that gets harder as you advance through the levels. You can play this logic game right in your browser without any annoying downloads or signups.
How to play
Press a cell with your mouse or finger and drag to another cell to draw a rectangle.
Simple rules:
- each rectangle must contain exactly one number;
- the rectangle area must match that number;
- rectangles must not overlap;
- the whole board must be filled.
For example, the number 6 means you need to make a rectangle of 6 cells around it. Valid shapes include 1x6, 2x3, 3x2, or 6x1, as long as they do not block other areas.
Features
- Grid logic mechanics: You must calculate dimensions precisely to ensure every cell of the board is accounted for.
- Adaptive difficulty: Early levels help you master basic shapes while later boards demand complex spatial reasoning.
- Clean interface: The visual style remains minimal to help you focus entirely on solving the numeric patterns.
- Auto-save progress: Your current session stays active so you can step away and return to your board later.
