Duel

Sudoku, chess-style.

  • 1 v 1
  • Turn-based
  • Ranked

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.

Duel in 10 seconds

  • Up to 3 digits per turn
  • Singles score 1 … wings and fish score 8
  • Guesses score 0, wrong digits cost 2

Best for: Thinkers. No rush, just better logic.

How Duel works

  1. 1

    Take turns

    Place up to 3 digits on your turn, then your rival places theirs on the same board.

  2. 2

    Harder logic, more points

    Each digit scores by the logic it needed: singles 1, pointing 2, pairs 3, triples 5, wings and fish 8.

  3. 3

    No guessing

    A correct digit that couldn't be worked out yet scores 0. A wrong digit costs 2 and ends your turn.

Questions

How are points worked out?

Each digit scores by the hardest technique it needed: singles 1, pointing 2, pairs 3, triples 5, wings and fish 8.

Why did my correct digit score 0?

Because it could not be worked out yet from the board. Duel rewards logic, not luck.
