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. Keep the game area visible while you use its controls. Use the opening round to become familiar with the layout. 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.
Take a closer look while playing
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
The objective of a round
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep that objective in view throughout the round. Take a moment to understand the current position.
The order of play
- 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.
The controls to know
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
See the idea in action
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 controls nearby.
A useful caution
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
