How to play Dots and Boxes

1. A square grid of dots. Players take turns drawing one line between two dots that sit side by side, across or down (never diagonally). Who goes first is decided at random.
2. Draw the FOURTH side of a box and the box is yours: it fills with your colour and your initial, you score a point, and you MUST draw another line. Close two boxes with one line and both are yours. Keep closing boxes and you keep drawing.
3. A line that closes nothing ends your turn.
4. When every box is claimed the game is over, and whoever holds the most boxes wins. A tie at the top is a draw.
5. Two to four players. Pick the board when you make the table: 5×5 boxes (the standard, 36 dots), 3×3 (quick) or 7×7 (long).
6. On your turn, tap anywhere near the line you want: the nearest line lights gold, and a tap draws it. The bar under the board counts the boxes left and the SAFE lines left: lines that give nobody a box. When the safe lines run out, somebody has to hand over boxes.

Dots and Boxes strategy

The basics that turn knowing the rules into winning games — what to do first, what to keep, what to avoid.

• Never draw the third side of a box unless you have to: it hands the next player that box, and often every box joined to it. Early on, play SAFE lines, the ones that leave no box with three sides.
• Watch the safe lines run out (the bar under the board counts them). Once none are left, every line gives something away, and the game is decided by who has to open the long chains.
• When you must give, give the least: a single box, or a chain of two. Open a chain of two by its middle line, so the taker cannot hand it back to you.
• The expert trick is the DOUBLE-DEAL. Taking a long chain at the end, take all but the last two boxes and draw the line at the far end instead. Your opponent gets those two, then has to open the next chain for you. Two boxes buys you all of the next one.
• Count the long chains (three boxes or more) as the safe lines dwindle. With two players, whoever is forced to open the first long chain usually loses, so steer the count of safe moves left to make it them.

Dots and Boxes FAQ

How do you play Dots and Boxes?

Players take turns drawing a line between two dots that sit side by side. Whoever draws the fourth side of a box claims it, scores a point and draws again. When every box is claimed, the most boxes wins.

Do you have to go again after closing a box?

Yes. Closing a box always means drawing another line, so a player can take a whole chain of boxes in one turn, and has to draw one more line at the end of it.

How many can play?

Two to four. Bots fill any empty seat, and you can pick a 3×3, 5×5 or 7×7 board of boxes when you make the table.

What is a double-deal?

Taking a chain at the end of the game, you take all but the last two boxes and draw the far line instead, handing those two to your opponent. They then have to open the next chain for you. It is the move that wins most close games.

Can I play against the computer?

Yes. The house bot plays safe lines while it can, gives away as little as it can when it has to, and uses the double-deal when it pays.
