Der lustige 7ner

Each player gets a game card and rolls two dice each turn. The result is covered with a game token on the game card. If a result is already covered it is only covered a second time, if the result consists of two identical numbers (für instance 4 and 4). On the roll of a 7 one token is removed from every number on the card. If the whole 2nd row is covered, the player uses only 1 die for the rest of the game. The first player to cover all numbers on his card, wins the game.
