An introduction to playing Shikaku
Make Shikaku your next activity in the game library. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Use the example below to understand a decision. Compare the starting position with the example in the Guide. Check the relevant rule before repeating a move.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
Practice beyond the first move
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
The goal to keep in mind
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. An attractive position is not enough unless the goal is met. The example below illustrates a decision.
Making your moves
- 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.
Keyboard and screen controls
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. Contact us with the game and device if a control does not respond.
An example before you play
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. Notice the change in the playing area.
A mistake to avoid
No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
