Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Something to practise
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
Your objective
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. An attractive position is not enough unless the goal is met. Check the rules when you are unsure.
How to proceed
- Choose a rectangle’s opposite corners.
- It must contain one clue and have the matching area.
- Click an existing rectangle to remove it.
- Cover every square to finish.
Choosing and moving on screen
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
Watch out for this
No rectangle may contain two clues or overlap another. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
