Introduction

1bet is a simple keno-based game by TvBet, a supplier of live dealer games to Internet Casinos. The idea is simple, the dealer will draw one ball from a bin with 37 balls and the player bets on what it will be, much like roulette.

Rules

  1. Balls numbered 0 to 36 are placed in a hopper.
  2. The player may wager on the next ball drawn. There are a host of different bets, as shown below in the analysis section.
  3. The dealer shall draw a ball.
  4. Bets are adjudicated, the ball is replaced back in the hopper, and a new game begins.
