Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.

Take a closer look while playing

After a move, check what changed. Decide which rule explains the new state before acting again. Keep the objective visible.

Understand the aim

Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. The example below illustrates a decision.

The steps to play

Cover every square to finish.

How your actions work

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Avoid pressing the same control repeatedly while a move is being processed.

Follow the 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. Take a moment to compare.

One detail worth checking

No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
