A sheet of squared paper with ink dots, lines between them and boxes filled in red and yellow

The paper game from the back of the exercise book

Almost everyone has played Dots and Boxes on squared paper in a boring lesson: a grid of dots, two pens, and a fight over every little square. It looks like a game for children. Then you notice that whoever is forced to open the first long chain usually loses, and it turns into a real strategy game.

On BeatMe you start a game, draw your first line and send the link. Your friend taps it, accepts with their name and plays in the browser. You do not have to be online at the same time: BeatMe keeps the sheet until the game is over. If you are both online, every line appears live on both screens.

How to play Dots and Boxes

Start a challenge

Type your name, pick the board size (9, 25 or 49 boxes) and who goes first. You get a short beatme.link link to send.

Draw one line per turn

Connect two neighbouring dots, across or down. Lines never go diagonally.

Close a box, go again

Draw the fourth side of a box and it is yours, with your colour and initial in it. Then you draw another line straight away.

Most boxes wins

Every board has an odd number of boxes, so there are no draws. The game ends as soon as one player holds more than half.

Dots and Boxes strategy: how to win more often

Never draw the third side. A box with three sides is a gift: your opponent closes it and keeps going. Early on, play lines that leave every box with two sides or fewer.
Count the long chains. Sooner or later every safe line is gone and someone has to open a chain. Whoever has to open the long chains first usually loses, so plan for that moment.
Learn the double-cross. When your opponent opens a long chain, take every box except the last two, then draw the line that leaves those two for them. They take two boxes, but they must open the next chain for you.
Give away small, take big. Sacrificing one or two boxes is often the right move if it means you get the next long chain.

Why play Dots and Boxes on BeatMe?

No lobby, no strangers and no app to install: one link in WhatsApp, iMessage, Telegram or any other chat, and a preview card that shows who challenged whom. Each closed box gets your initial, the lines from the last turn light up so you can see what changed while you were away, and the finished game comes with a result card and a replay.

Dots and Boxes FAQ

Can I play Dots and Boxes online with a friend for free?

Yes. Start a game on this page, send the link and your friend plays in their browser. It is free, with no app, no account and no ads in the way of the board.

What happens when I close a box?

The box is yours and you draw another line straight away. If that line closes another box, you go again, so one good turn can take a whole chain of boxes.

Can Dots and Boxes end in a draw?

Not here. Every board has an odd number of boxes (3×3, 5×5 or 7×7), so one player always ends up with more.

Why does the game end before every box is filled?

Once one player holds more than half of the boxes, the rest cannot change the result, so BeatMe calls it right there instead of making you draw the last lines.

Do we have to play at the same time?

No. Each player draws whenever they like. The link keeps the game for 48 hours after the last move. If you are both online, lines show up live.

What is the game called in other countries?

In Germany it is Käsekästchen, in Mexico Timbiriche, and in France the jeu des petits carrés or la pipopipette, the name the mathematician Édouard Lucas gave it in 1889.
