Making your first moves in Shikaku

An idea for your next attempt

When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Refer to the controls when needed.

The objective of a round

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. Review the board or playing area as it changes.

How a round unfolds

  1. Choose a rectangle’s opposite corners.
  2. It must contain one clue and have the matching area.
  3. Click an existing rectangle to remove it.
  4. Cover every square to finish.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.

Put the rules into context

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. Consider the next action carefully.

Watch out for this

No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
