Learn the rules of Shikaku
Start Shikaku by looking at the playing area and its controls. Cover the board with non-overlapping rectangles, each containing one clue equal to its area. Check the relevant rule before repeating a move. Use the opening round to become familiar with the layout. 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 with a purpose
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.

An example before you play
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. Verify the rule before continuing.
Where a round can go wrong
No rectangle may contain two clues or overlap another. Check the rule before repeating the action. 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.
