Sudoku Brawl allows you to play simultaneous, head-to-head games of Sudoku against up to 3 other players.

Each round is played like a traditional Sudoku game. When any player solves a tile, it is revealed for everyone. The round lasts until the entire grid is revealed.

Players earn points for revealing tiles. A tile is worth the minimum number of empty tiles in its row, column or block. For example, the last tile in a row or column is only worth 1 point.

A time penalty is incurred for guessing an incorrect number. This penalty is based on the tile value and round difficulty. Other players will see your penalty flash on the grid.

While you have a tile highlighted, it is reserved. You can score a reserved tile even if another player reveals it first. The final tile in the round cannot be reserved.

After each round, stars are divided among the players in proportion to their score. The player in first place takes all of the crowns.
