Shikaku: from controls to your first round
Choose a round of Shikaku and settle into its rules. 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. Read the objective before making your first input. 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.
Practice beyond the first move
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
Aim for this result
Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Read that aim before choosing your first action. Start with a deliberate move.
The order of play

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. Use one clear input at a time.
An example before you play
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Compare this with the rule that governs the move. Take a moment to compare.
Check this before moving on
No rectangle may contain two clues or overlap another. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
