A practical guide to Shikaku
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. Choose a clear next step rather than rushing through the instructions. 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.
Practice beyond the first move
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.
What the game asks you to do
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. Return to the instructions when a step is unclear.
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.
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. A careful first action helps you become familiar with the layout. Return to the rules if the result is unexpected.
Learn from a sample situation
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. Read the matching step again.
A useful caution
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
