Roulette is the most iconic casino game in the world where luck and strategy intertwine. BGD99 offers many high-quality versions to serve both newcomers and long-time experienced members. Let’s explore in detail the factors that create the sustainable appeal of this legendary game right below.
Introduction to Roulette game in every BGD99 casino
Roulette maintains its appeal through the centuries thanks to its simple mechanism but provides a distinctive thrilling experience. The game continuously expands its influence from Monte Carlo casinos to online platforms covering the globe.

History of formation
The wheel was invented by French mathematician Blaise Pascal in the 17th century during research on motion. By 1796, the game officially appeared in Paris casinos with a structure similar to the modern version. From Europe, the game spread to America in the 19th century, gradually forming unique variants.
Structure of the game table
The game table is designed with two main components: a spinning wheel and a betting layout that work together seamlessly. Below are the core components that make up a standard game table for easy understanding by members:
- The wheel contains pockets numbered from 0 to 36, alternating in red and black colors according to system regulations.
- A metal ball rolls in the opposite direction of the wheel and randomly stops in any pocket on the table.
- The inside betting layout is the area for placing direct bets on specific pockets on the system table.
- The outside betting layout is the area for placing bets on color groups or even/odd on the system table.
- The Dealer is the person who manages the game, spins the wheel, and announces the results to participants.
Operating mechanism
Each game starts when the dealer opens betting, allowing participants to place chips on their desired positions before the wheel spins. The metal ball rolls in the opposite direction of the spinning wheel, slows down, and falls into a random pocket when it stops. All chips placed on positions corresponding to the winning pocket will receive rewards according to the predefined ratio of the system.
Popular Roulette versions on the market today
Roulette has developed into many different versions over the centuries, each with its own unique wheel structure and RTP rate. Understanding the differences between versions helps participants choose the most suitable table for their strategy.

Distinct betting systems on every Roulette wheel
Roulette offers a multi-layered betting system, ranging from simple bets on colors to complex combinations. This richness allows participants to flexibly adjust their tactics according to the desired level of risk in each game.

In bets
In bets are a group of bets placed directly on specific cells or intersections between cells on the game board layout. The payout ratio of this group is much higher than that of outside bets but comes with a significantly lower winning probability. Straight Up is the most common type of in bet, placed directly on a single cell with a payout ratio of 35:1.
Outside bets
Outside bets are a group of bets placed according to broad categories covering nearly half or one-third of the total number of cells on the wheel. The table below lists popular outside bets and their corresponding payout ratios on the BGD99 system for your reference:
| Bet Type | Coverage | Payout Ratio |
| Red/Black | 18 same-color positions | 1 : 1 |
| Odd/Even | 18 odd or even positions | 1 : 1 |
| Low/High | 1 to 18 or 19 to 36 | 1 : 1 |
| Dozen | 12 consecutive positions by group | 2 : 1 |
| Column | 12 positions by vertical column on the board | 2 : 1 |
Special bets
Special bets originate from European tradition based on the physical position of cells on the wheel. Below are the most popular special bets in both French and European versions for easy grasp by members:
- Voisins du Zéro covers 17 cells around the 0 cell on the BGD99 system wheel.
