Divide the entire grid into rectangles so that each rectangle contains exactly one number, and that number equals the rectangle's area.

gavelRules

• Every rectangle must contain exactly one number
• A rectangle's area must equal the number inside it
• Rectangles cannot overlap and every cell must be covered

sports_esportsHow to Play

• Drag across the grid to draw a rectangle
• The running area shows as you drag, so you can size it before you commit
• A new rectangle replaces any it overlaps
• Tap inside a rectangle to remove it
• A number turns green once the rectangle around it is correct
• Keyboard: arrows move the cursor, Space picks two corners, Delete erases, Z undoes

lightbulbTips

• Start with clues in tight corners where only one shape fits
• A number's rectangle can extend in any direction, not just down or right
• Two clues can never share a rectangle, so they push boundaries apart
