Frequently Asked Questions

How do you win Dots and Boxes every time?

The secret is mastering the Double-Cross. When given a chain of boxes, capture all but the final two boxes, then forfeit those two boxes by drawing an internal dividing line. This forces your opponent to take the final two boxes and break open the next chain for you, giving you control of the board.

What is the winning strategy for 6x6 and 5x5 grids?

A 6x6 dot grid contains 25 boxes (an odd number), meaning ties are impossible and the first to reach 13 boxes wins. Success on 6x6 grids relies on parity control over long chains (3+ boxes) and making strategic 4-box loop sacrifices to sweep the largest remaining corridors.

Can I play with 2 players locally on the same screen?

Yes! Switch the mode selector in the top bar to 2 Player to play local pass-and-play with custom player names and colors on any smartphone, tablet, laptop, or desktop.
