Clash: the race
You both solve the same puzzle. Completing a row, column or box charges powers: Fog, Ice, Blind and Shuffle slow your rival down, and finishing more units blocks their attacks.
Duel: turn by turn
Take turns placing up to three digits. The harder the logic you used, the more you score: singles, pairs, triples and beyond. A wrong guess costs points.
Territory: claim the board
One shared board. Every correct digit claims a cell in your colour, and owning most of a row, column or box when it completes locks it for a bonus.
How to start a 2 player game
- Choose Clash, Duel or Territory.
- Tap Quick match to play someone at your level, or Challenge a friend to get a link you can share.
- When the second player joins, the match starts. Both of you get the same puzzle.
Which 2 player mode fits you?
If you solve quickly and enjoy pressure, play Clash. It rewards speed, and its powers add a layer of timing: fire an attack when your rival is about to complete a row, or hold your own row back to block theirs.
If you like to take your time, play Duel. With turns of up to three digits and no clock race, it is closer to chess than to a sprint. You are looking for the placement that scores most, and trying not to open up a high-scoring one for your opponent.
If you like fighting over space, play Territory. The lock bonus means a row you have three cells in is worth defending, and one your rival is about to lock is worth contesting.
Scoring in Duel
Duel gives points by the logic a digit needed: 1 for a single, 2 for pointing, 3 for a pair, 5 for a triple and 8 for an X-Wing, XY-Wing or Swordfish. A digit that could not be worked out from the board scores nothing, and a wrong digit costs 2. If you want to score well, the technique guides explain each pattern with a real example.
Two players, one device?
Sudoku Clan is built for one device per player, because the modes rely on each of you seeing your own view. If you only have one phone to hand, take turns at the daily puzzle and compare times, or print two copies of the same sheet from the printable puzzles page and race on paper.
See how Duel works
Take turns on one shared board, up to three digits per turn. Each digit scores by the logic it needed, so a clever deduction is worth far more than an easy fill. Lucky guesses score nothing.

Clash is the most action-packed, Duel rewards careful logic, and Territory is a race for space on one shared board. Try all three; each has its own rating.
Can I play 2 player Sudoku offline?
Practice matches against bots work offline once the game has loaded. Playing a person needs an internet connection.
How do two people play Sudoku against each other?
Both players get the same puzzle. In Clash you race to finish first, in Duel you take turns and score points for logic, and in Territory you claim cells on one shared board.
Is 2 player Sudoku fair if one player is much better?
Quick match pairs you with players of a similar rating. With a friend of a different level, Duel and Split Sight are the most balanced modes.
