THE PLAYBOOK · ZZBSDZ
The Shikaku playbook
Bring your attention to one round of Shikaku. 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. Make your first input carefully and watch the result. Look at what changes after your first action.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
One thing to notice as you play
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
Your goal
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. Keep the controls in easy reach.
From the start of a round
- 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 use the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Use one clear input at a time.
A closer look at one example
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. Notice the change in the playing area.
Keep this in mind
No rectangle may contain two clues or overlap another. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
