Five ways to play Sudoku together
Every mode uses classic 9×9 Sudoku rules, so there is nothing new to learn. What changes is who you play with and how you win.
Fair, logic-only puzzles
Every puzzle has exactly one solution and can be solved without guessing. Both players always get the same puzzle at the same difficulty, so the better solver wins.
Ranked, with leagues
Each mode has its own rating. Climb from Bronze to Grandmaster, earn trophies, and unlock avatars, reactions and board themes on the Trophy Road.
