Rectangles is an area logic puzzle. The grid is scattered with numbers, and your job is to split the whole grid into rectangles (squares count too) so that every rectangle holds exactly one number, and that number is the rectangle's area: a 6 covers six cells, as a 2x3, a 3x2 or a straight line of six. Every puzzle has exactly one solution, and you can always reach it by logic alone.
How to play Rectangles
Cover Every Cell
Divide the whole grid into rectangles. Every cell belongs to exactly one rectangle, and rectangles never overlap.
One Number Each
Each rectangle holds exactly one number. A rectangle with no number, or with two, breaks the rules.
Number = Area
The number inside a rectangle is its area: how many cells it covers. A 1 is a single cell; a 4 can be a 2x2 square, a 1x4 or a 4x1.
Draw by Dragging
Drag from one corner to the opposite corner to draw a rectangle. Its size shows while you drag. Tap a rectangle to remove it.
Check and Hints
Check turns any rule-breaking rectangle red. Hint explains the next logical step in plain words.
Pure Logic
No guessing required. Every puzzle has a unique solution that you can reach one deduction at a time.
Strategy & solving tips
Good Rectangles solving starts with the numbers that have the fewest options. These techniques, from easiest to hardest, cover every puzzle in the game.
- Start with numbers that fit only one way: a 1, a number pinned in a corner, or a big number boxed in by its neighbors
- Look for a cell that only one number can reach: that number's rectangle must cover it
- Find cells that every possible rectangle of a number covers: those cells are taken, so other numbers can't use them
- Prime numbers like 5, 7 and 11 can only be straight lines, which makes them easy to place on small boards
- Test an option in your head: if drawing it would leave another number with no room, or a cell nobody can reach, it's wrong
- Every drawn rectangle shrinks the options around it, so place the sure ones first and look again
Rectangles FAQ
Do squares count as rectangles?
Yes. A 4 can be a 2x2 square, and a 9 can be a 3x3 square, as well as longer, thinner shapes.
Can a rectangle hold no number?
No. Every rectangle holds exactly one number, so the number of rectangles always equals the number of numbers on the board.
How do the difficulty packs differ?
Easy boards (5x5 to 7x7) only need numbers that fit one way. Medium (8x8, 9x9) adds cells only one number can reach, Hard (10x10 to 12x12) adds cells every option covers, and Expert (13x13 to 15x15) needs you to test an option and see it fail.
Is there a daily puzzle?
Yes. A new board arrives every day, easier early in the week and hardest on Sunday, with a streak and a daily leaderboard.
