Rectangles

How to play

Split the grid into rectangles. Each one holds a single number, and its size has to be that number.

• Drag across the grid to draw a rectangle; the number inside it must match how many cells it covers.
• A new rectangle replaces any it overlaps, so you can redraw freely.
• Tap a single cell inside a rectangle to remove it.
• You win when every square is inside a rectangle and all the numbers match.
• A rectangle whose area does not match a single number is refused and costs a heart.

Tips

• Start with prime numbers — they only fit as a 1×n strip, so there are few options.
• A number in a corner has few options: often only one shape fits.
• Every puzzle has exactly one solution, so a forced rectangle is always safe to place.
