Double Twist Blackjack is a game I noticed at the Stratosphere in Las Vegas on February 2, 2016. It bills itself as a new game concept, but it is really just blackjack with an optional side bet. For this reason, I am classifying it as a side bet rather than a unique game.
- The game is based on conventional blackjack rules.
- There are two betting spots per player.
- The player may make a side wager on each betting spot.
- The side wager pays based on the player's initial two cards and the dealer's up card.
- The pay table is shown below. I presume that the player is paid based on the highest win only.
