IntroductionRoyal 20's is a blackjack side bet based on the player's first two cards. If they total 20 points, the player wins up to 25 to 1. I saw it at the Cannery casino in Las Vegas on Feb. 28, 2017, but know it has been around since at least 2012.
- The game is based on blackjack with ordinary 52-card decks.
- The Royal 20's side bet shall pay according to the player's first two cards and the pay table below. All wins are on a "to one" basis.
