Play Dots and Boxes online with a friend
Create a room, send the link, and you're drawing lines together in seconds.
Online Dots and Boxes here works like a private table: one player creates a room and shares a link or 4-letter code, the other taps it, and the same board opens on both screens. Every line shows up on both devices the moment it's drawn, closing a box still earns an extra turn, and the scoreboard settles it at the end. There's no account, no download and nothing saved anywhere.
Create your room
Pick a board size and tap Create room. You get a 4-letter code and a share link that opens the same table on any phone, tablet or computer.
Send the link to one friend
Paste it into any chat. When your friend taps Join, the board goes live on both screens and the first move is yours.
Play, rematch, keep the series
Close a box to draw again, just like on paper. When the grid fills up, tap Play again — the opening move swaps each game, so rematches stay fair.
How the private room works
A room is a direct line between two browsers. The 4-letter code is simply the address your friend's browser dials; once the connection is up, every move travels straight between the two devices. We never see the moves, the names or the result, because none of it passes through a server — and when both tabs close, the room stops existing.
You always join in pairs. There are no strangers dropping into your board and no public list of open games — a match only starts when someone opens your exact link or types your code.
Dropped tabs, trains and tunnels
Refreshed by accident? The game doesn't die. Both browsers keep trying to re-dial the room for a few minutes, and the board reappears with every line exactly where it was. If you were hosting, reopening the page offers to resume the room with one tap. Long tunnels and dead zones are the real enemy: the board simply pauses until the connection returns.
Good games to play over a call
Voice chat plus Dots and Boxes is a great combo: the trash talk flows while the board stays honest. Start small on a 3×3 while you say hi, then move to 5×5 or 6×6 for the main event. Closing two boxes with a single line is called a double-cross — learn it on the strategy guide and you'll hear the groan down the line.

Online play questions
How do I play Dots and Boxes online with a friend?
Tap Create room, choose a board size, then send the link or 4-letter code to one friend. When they open it and join, the same board goes live on both screens and you take turns exactly like the paper game.
Does my friend need an account to join?
No. There are no accounts, no email and no passwords anywhere on the site. Your friend just opens the link, optionally types a name, and starts drawing lines.
Can we play across a phone and a computer?
Yes. The board is a normal web page, so any modern browser works — phone, tablet, laptop or desktop. You can start on a laptop and have your friend join from their phone in seconds.
What happens if one of us closes the tab?
Nothing is lost right away. Both browsers keep trying to re-dial the private room for a few minutes, so a refresh or a brief drop usually reconnects on its own. If the host reopens the page, tapping Resume brings the exact board back.
Who goes first in an online game?
The host draws the first line of game one. After that, the opening move swaps to the other player each rematch, so long series stay fair.
Is it free, and is anything stored about us?
It's completely free. Moves travel directly between the two browsers, so names, moves and results aren't stored on any server.
The link isn't connecting — what's wrong?
Some school, office and hotel Wi-Fi networks block direct browser-to-browser connections. Try mobile data or a home network. The code itself only has four characters, so double-check it too.
