Ways to play
Tournament
2–18 players across 3 rounds. The lowest scorers get cut between rounds until a winner is left. Bots fill empty seats so games start instantly.
Duel
1v1, one round. Match in seconds. Three minutes to settle it.
Practice
Solo. Unlimited puzzles. Warm up before you queue ranked.
Sharpens intuition. Speeds up calculation.
Sudoku trains two skills at once. Pattern intuition: you see where a number goes before you’ve worked it out. Calculation: you eliminate candidates row by row, column by column, until a cell is forced.
Most sudoku apps give you all the time in the world, so you only train the slow side. Battle royale puts a clock on it. Faster solver takes the cell and the points. Switching between fast and slow under pressure builds working memory and decision speed — useful well beyond the board.
