Kaku brings the classic rectangle-division puzzle Shikaku to your browser with 2,000 handcrafted levels across four difficulties. Every rectangle you draw must contain exactly one number, and that number must equal the number of cells the rectangle covers — split the whole board with no gaps or overlaps to clear the stage. Easy boards ease you in, while Expert 13x13 grids will genuinely test your spatial logic. Daily challenges with monthly trophies and a growing IQ score give you a reason to come back, and hints are on hand whenever a board has you stumped.
How to play
Draw a rectangle so it contains exactly one number, matching the count of cells it covers. Fill the entire board with rectangles, leaving no gaps or overlaps, to clear the level. Tap a placed rectangle to remove it, or use a hint to reveal one correct rectangle.
Controls
Drag across the board (hold the left mouse button, or swipe on touchscreens) to draw a rectangle. Tap an existing rectangle to remove it.
