Take turns drawing one line between two dots that are next to each other — never diagonal.
Tap the gap between two neighbouring dots to draw a line there.
Three sides already there — draw the last side and the box is yours, marked in your color, and you get another turn immediately.
- Closing two boxes with one line (a shared side) claims both, and still earns just the one extra turn.
- Chains matter: giving your opponent the third side of a box can hand them a whole run of boxes in a row.
- When every line on the board is drawn, whoever has claimed the most boxes wins.
