Paper Games
How to play Dots and Boxes
Add one grid edge at a time, claim squares you close and take another move after completing a box.
What you need
Paper with a rectangular dot grid and pens or pencils; use initials to identify claimed boxes
Set up the game
- Draw five rows of five dots for a 16-box board, or choose a smaller rectangle. Do not draw the outside border in advance.
- Choose who begins and use different initials. Color is helpful but not necessary.
Playing Dots and Boxes
- Draw one unused horizontal or vertical line joining neighboring dots. No diagonal or multi-space lines.
- If the line completes a box’s fourth side, mark your initial inside and take another move. If it completes two boxes, claim both, then continue.
- When a move closes no box, the other player goes. Continue until every box is claimed.
- Count boxes, not lines: the higher total wins; equal totals are a draw.
One final edge, two initials
Two adjacent boxes each lack only the line between them. Drawing that shared line finishes both. Mark your initials in both squares and make another move. You earn two boxes but only one continuing move at a time, not a bank of two saved turns.
An edge can be shared by two boxes
Interior edges touch two potential boxes; border edges touch one. Inspect both sides of a proposed line. A move that looks harmless from the left may create a nearly finished square on the right. Initials make ownership clear even if every line is drawn in the same pen.
Beginner decisions
- Before drawing a third side, look for a line elsewhere that gives no immediate box away. Later, compare how many boxes each available opening may release.
Common rule mix-ups
- Alternating turns immediately after closing a square.
- Counting five-by-five dots as 25 boxes rather than 16.
