Pixtangle: Shikaku Rectangles Live

Pixtangle is a relaxing shikaku puzzle game: slice the grid into rectangles by the number clues, fill the whole board, and watch it bloom into a pixel art. A calm, satisfying logic puzzle for fans of number and grid puzzles — simple rules, clean deduction and that little click when the last rectangle falls into place. HOW TO PLAY SHIKAKU Each rectangle must contain exactly one number, and that number is the rectangle's area in cells. Any correct split of the board wins. A quick interactive tutorial walks you through your first board move by move — and the pear you color in along the way becomes the first art in your collection. • Drag your finger to draw a rectangle around a number • Every rectangle holds exactly one number clue • The number equals how many cells the rectangle covers • Fill the entire board to solve the puzzle SIX DIFFICULTIES THAT GROW WITH YOU Five minutes on the bus or a whole quiet evening — there is always a new board waiting.
