How to play Shikaku
Choose a round of Shikaku and settle into its rules. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Look at what changes after your first action. Keep the instructions close while learning this activity. Choose a clear next step rather than rushing through the instructions.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Make the next step deliberately.

Controls

A useful example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Take a moment to compare.
Watch out for this
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
