How to play Dots & Boxes
- 1Choose your grid size (3x3, 4x4, or 5x5) and whether to play a friend or the AI.
- 2On your turn, tap one empty line between two neighbouring dots to draw it.
- 3When you draw the fourth side of a box, you claim it - and you take another turn.
- 4Keep drawing extra lines as long as you keep completing boxes.
- 5Try to avoid drawing the third side of a box, which hands your opponent a free one.
- 6When every box is claimed, whoever owns the most boxes wins the game.
Dots and Boxes is a classic pencil-and-paper strategy game first published in the 1880s. The trick to winning is the 'chain rule' - deliberately sacrificing small chains of boxes early so you can scoop up the big chains later. Master the double-cross move and you'll beat almost anyone.
Frequently asked questions
How do you win Dots and Boxes?＋
Complete more boxes than your opponent. You claim a box by drawing its fourth side, and completing a box lets you move again - so long chains can swing the whole game.
Why did I just give my opponent lots of boxes?＋
Drawing the third side of a box lets the next player complete it. Skilled players avoid this until forced, then give away the smallest chain possible.
Can I change the board size?＋
Yes - pick 3x3 for a quick game or 5x5 for a longer, more strategic match. You can switch any time and it starts a fresh board.
Is it free?＋
Yes, completely free with no sign-up and no downloads. It works on any phone, tablet, or computer.
