Shikaku vs CornerWISE

Shikaku is a calm logic puzzle about dividing a grid into rectangles. Each number is a clue: draw one rectangle around it, and make the rectangle's area match the number. Every rectangle must contain exactly one clue, and the whole board must be covered. Play quick puzzles with four difficulty levels, take on a fresh daily puzzle, and track your best times and streaks. The hand-drawn paper board keeps the focus on solving: drag to draw, tap to erase, undo mistakes, clear the board, or use a hint when you are stuck.
