In Sudoku: Duell der Meister, the board is the standard 9x9 grid split into 3x3 blocks. Each player gets 12 scoring markers and 36 number tiles in his colour. These are mixed up face-down. Nine golden numbers are placed onto the board so that there's a single number in each 3x3 block. Players take turns revealing one of their numbers and adding it to the board (following the rules of Sudoku). As soon as a player has a majority in a row, column, or block, he places one of his scoring markers onto the matching scoring spot along the edge of the board. In the event of a tie, the player with the highest number sum gets to place the marker. The goal of the game is to be the first one to claim 12 majorities. —description from the publisher
