From the start of a round
- 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.
Using the playing area
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 one clear input at a time.
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. Look for the relevant detail.
A common point of confusion
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
