How to play Shikaku
SLTPPF presents Shikaku with a practical playbook rather than a download screen. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read the careful restarts note before you begin.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Careful restarts
Start a fresh round when you want another attempt. Restarting may discard current progress; read the controls rather than assuming an account backup exists.
Your goal
Cover the board with non-overlapping rectangles, each containing one clue equal to its area.
Step by step
- 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.
Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution.
A useful example
A clue 6 may occupy a 2×3 rectangle when other clues allow it.
Watch out for this
No rectangle may contain two clues or overlap another.
