The Shikaku playbook
Start Shikaku by looking at the playing area and its controls. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Check the relevant rule before repeating a move. Compare the starting position with the example in the Guide. 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.
A focus for your next round
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. Keep the objective visible.
The challenge in front of you
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Take a moment to understand the current position.
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. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
An example before you play
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. Read the matching step again.
A common point of confusion
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.
