The essentials of playing Shikaku
Use a short break to learn the rhythm of Shikaku. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Look at what changes after your first action. Compare the starting position with the example in the Guide. Use the example below to understand a decision.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Practice beyond the first move
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.

Your inputs
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. Read the example below alongside these instructions.
Try this example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Apply the same reasoning to the position in your own round. Keep the game’s format in mind.
Watch out for this
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
