Dot Duel
About this game
Draw edges between dots to complete squares. The main Play button opens solo puzzles with an opening-move budget, while Vs Nora and 2 players offer competitive games. Check the selected mode before planning: solo efficiency and competitive turn control are different goals.
Controls
Drag between neighboring dots, tap an unused line, or select an edge with arrow keys and Enter. Read the opening-move counter in solo puzzles.
How to play
- Solo puzzles require every square to be closed and have no opponent.
- A solo line closing no square costs one opening move; closing one is free.
- Closing two squares in one solo move earns one opening move.
- In competitive modes, completing a box claims it and grants another turn; the higher total wins.
Ways to play better
- At zero opening moves, inspect free closing lines before giving up.
- Look for a shared edge that completes two neighboring squares.
- Against an opponent, compare the chain you give away after your move.
Common questions
Why did my remaining moves not decrease?
In a solo puzzle, closing one square is free and closing two earns a move. Only a non-closing line spends an opening move.
Can two people play without separate accounts?
Yes. The 2 players option is a local game on the same device.
Do I need an account to keep playing?
