Double-Up Blackjack was created, designed, developed and is wholly owned by Score Gaming LLC. Double-Up Blackjack is inspired by traditional Blackjack but takes the game to the next level by giving players the chance to double their wager after having seen their first two cards (except natural Blackjacks). To Double-Up all the player has to do is place an optional additional bet equal to their original wager and stand on their two-card hand.
