Making your first moves in Shikaku
Shikaku gives you a focused activity to play in your browser. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Look at what changes after your first action. Begin with the solo mode shown on the page. Keep the game area visible while you use its controls.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Take a closer look while playing
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
What you are aiming for
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Use the instructions to see which actions move you towards it. Start with a deliberate move.
Follow these playing steps
- 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.
Making selections and moves
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. A new-round button replaces the current round.
A useful example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Use the example as a guide rather than a substitute for reading your board. Notice the change in the playing area.
One detail worth checking
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
