Getting started with Shikaku
Use a short break to learn the rhythm of Shikaku. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Look at what changes after your first action. Compare the starting position with the example in the Guide. Check the relevant rule before repeating a move.
Solve ten 5×5 rectangle puzzles. Each clue belongs to exactly one rectangle of the stated area.
An idea for your next attempt
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Notice the feedback after each input.
What counts as success
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Review the board or playing area as it changes.
Work through the instructions
- 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.
Input guidance
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
Follow the 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. Take a moment to compare.
Watch out for this
No rectangle may contain two clues or overlap another. Check the rule before repeating the action. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
