Players in Miss Lupun...und das Geheimnis der Zahlen start each round with ten number tiles (0-9) and four task cards, of which they must keep three. These task cards feature challenges such as "Have two of the same number in row 5", "Have the tiles in a row sum to more than 10" and "Have the tile on B2 be larger than the one on C4".
Each turn, a player places one tile on an empty space in the 4x6 grid on the game board. Once the board is filled or two players run out of tiles, the round ends. Players reveal their task cards and keep those that they've achieved. After a certain number of rounds, the player who has collected the most cards wins.
