How a Sudoku race works

A fair race removes every difference except how the players solve.

  • Choose Race on the multiplayer Sudoku page.
  • Select a difficulty and create a private friend match.
  • Share the invite, solve the same puzzle, and compare the result.

Race without guessing

Speed matters only when the puzzle is solved accurately.

  • Scan for forced placements before rushing into notes.
  • Use the same mistake rules for both players.
  • Warm up on the daily Sudoku if one player wants a practice round.
