How to Play Dots & Boxes Online
Dots and Boxes is the classic pencil-and-paper game for two players, played here on a 4x4 grid of boxes. Draw lines between dots, and complete a box's fourth side to claim it and go again.
Objective
Claim more boxes than your opponent by completing their fourth and final side.
Setup
- The board is a fixed 4x4 grid of boxes (a 5x5 grid of dots).
- Players take turns drawing one line at a time between two adjacent dots.
- You have 30 seconds per move before a random undrawn line is played for you.
How to Play, Step by Step
Draw a line
On your turn, draw one line between two adjacent dots, horizontal or vertical.
Watch for the fourth side
If your line completes the fourth side of a box, you claim that box.
Go again after a box
Completing one or more boxes on your line means you immediately take another turn.
Pass if you complete nothing
If your line doesn't complete a box, the turn passes to your opponent.
Rules to Know
- The board is a fixed 4x4 box grid — 16 boxes in total.
- Completing one or more boxes with your line keeps your turn; completing none passes it.
- A box is claimed by whoever draws its fourth and final side.
- The game ends when the grid is full; whoever owns more boxes wins, and an equal split is a draw.
