Blackjack or Bust

Blackjack or Bust is a competition that originated in Big Brother 1.

Rules
In this competition, Houseguests will play a game of Blackjack conducted on random.org. Each Houseguest and the dealer will be dealt 2 cards. The object of the competition is to beat the dealer's hand without going over 21. If the dealer hits 21, the Houseguest loses that hand.

Aces are worth 1/11, face cards worth 10, and number cards hold their numerical value. The dealer must hit on 16 and lower. Each time you beat the dealer's hand, you score 1 point. The Houseguest with the most points at the end of 5 rounds wins the competition. In the event of a tie, there will be a tiebreaker round.
