Spread-Bet Roulette

Introduction

Spread-Bet refers to a category of additional bets in roulette developed by Cammegh, a company renowned for producing gaming equipment such as roulette tables and signage. The results hinge on the combined total of two electronic spins, which are displayed to the player on a digital screen during the game.

Rules

Spread-Bet consists of seven optional side bets that can be incorporated into a traditional roulette game. Here are the guidelines to follow.

  1. In addition to the usual spin of the roulette wheel, two random results are simultaneously generated electronically and presented to the player on a digital scoreboard through two overlapping roulette wheels.
  2. The two virtual spins will utilize the same type of roulette wheel as the physical one, meaning they will all feature an identical number of zeroes.
  3. There are seven different betting options, which will yield wins based on the total from the two virtual spins. These betting options will be located in the area designated for outside bets.
  4. Winnings from Spread-Bets are determined by the combined score of the two virtual spins, where both single and double zeroes are counted as zero in this context.
  5. The seven types of Spread-Bets encompass various score ranges from 0 to 72. Different configurations are accessible to casino operators, as detailed in the analytical section of this webpage.
