Box Claim

Take turns drawing lines between dots and claim every box you close. Finish a box and you move again. A tactical dots-and-boxes duel against the computer.

How to play

  1. The board is a grid of dots. On your turn, tap the gap between two neighbouring dots to draw a line.
  2. If your line completes the fourth side of a box, you claim it and take another turn straight away.
  3. Otherwise the turn passes to the computer.
  4. When all 16 boxes are claimed, the player with the most boxes wins.

Tips and strategy

  • Never draw a third side of a box unless you have to. It hands your opponent a free box.
  • Always take boxes that are on offer, but watch for long chains: sometimes it is better to give the last two boxes away to keep control.
  • Count the safe lines left. The player who runs out of safe moves first has to open a chain for the other.
  • One line can close two boxes at once, so look for lines between two boxes that both have three sides.

FAQ

Why do I get another turn after claiming a box?
That is the standard rule of dots and boxes. It makes closing boxes valuable and creates the chain tactics that decide most games.
Can the game end in a draw?
Yes. With 16 boxes the score can be 8 to 8, which is shown as a draw.
What does the hard computer do differently?
Both medium and hard take free boxes and avoid giving them away. When every move gives something up, hard picks the line that gives away the fewest boxes.
