Turn3 Roulette Side Bet
Introduction
The Turn3 is a side bet in roulette. The only placement I'm aware of is at the Barona in California, where a method other than a ball alone must be used to determine the outcome. Most casino use cards. The outcome of the Turn3 is based on the card that represents the winning outcome for standard roulette bets, plus two more.
Rules
Following are the rules for the Turn3, as played at the Barona in California.
- A 37-card deck is used, with one card for every possible outcome in single-zero roulette.
- In addition to all the standard roulette bets, there is the Turn3.
- After betting is closed, the first card in the deck will determine the outcome of all standard roulette bets.
- Then, two more cards will be dealt. The Turn3 will pay based on all three cards and the following pay table:
- 0-1-2 straight: 100 to 1
- All other straights: 25 to 1
- All same color: 3 to 1
