An introduction to playing Shikaku
Open Shikaku, check the instructions and begin a round. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Check the relevant rule before repeating a move. Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
A small practice goal
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Use the example to check your reasoning.
Understand the aim
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. The feedback beside the game helps you follow the round. Start with a deliberate move.
The steps to 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.
How to interact with the game
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. Make sure you are interacting with the game rather than the surrounding page.
Learn from a sample situation
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Your next round may have a different position, so inspect it before acting. Read the matching step again.
Watch out for this
No rectangle may contain two clues or overlap another. A different version of the game may use a different rule. 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.
