Kuadra — Shikaku Puzzle
Logic number grid brain game
Free · Designed for iPad. Not verified for macOS.
Kuadra is a beautifully simple Shikaku puzzle — divide the grid into rectangles, one number at a time, and quiet your mind while you do it.
The rules take ten seconds to learn and a lifetime to master. Every grid has exactly one solution: split it into rectangles so each contains a single number, and that number equals the rectangle's area. No guessing, no luck — just pure logic.
