Fill or Bust is a game about rolling dice and pressing your luck. On your turn, roll the dice and set aside anything that scores you points. If you want, roll the remaining dice - but if none of the dice rolled score for you, you lose all points accumulated that round! This is further complicated by a deck of cards that determines what specific goals you should have for the turn. Just like scoring points with the dice, if you meet a card's goal you can turn over the next one and try, but the next card might end your turn.
The game is extremely similar to Farkel, not counting the deck of cards.
