Understand the basics of Shikaku
Shikaku gives you a focused activity to play in your browser. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Keep the game area visible while you use its controls. Check the rule that explains your first action. 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.
Give this approach a try
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. Refer to the controls when needed.
The challenge in front of you
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Try to explain the aim in your own words.
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.
Getting comfortable with 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. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.
One way to understand the rules
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Consider the next action carefully.
Notice this detail
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
