Shikaku vs Pixtangle

Master the Geometry of Logic. Step into the world of Shikaku (also known as Rectangles), a classic Japanese logic puzzle reimagined for the modern era. Shikaku is a minimalist experience designed for those who find beauty in structure and peace in problem-solving. THE GOAL Divide the grid into rectangular and square pieces such that each piece contains exactly one number. That number must represent the total area (the number of cells) of that rectangle.
