Over/Under (O/U) ( blackjack)

 

Two side bets that can be made in blackjack. In the over bet, the player is wagering that his two card total will be less than 13. In the under bet, the player is wagering that his total will be more than 13. In either case, if the total is exactly 13 the player loses. Aces count as one in considering the card totals.
