This SBONOVA (스보노바) ROULETTE guide explains how roulette works, what the main bets mean, how payouts are calculated and why wheel type matters. Roulette looks simple—players place chips, the wheel spins and the ball lands on a numbered pocket—but understanding probabilities and bet structures makes the game much easier to follow.
SBONOVA Roulette Basics: How the Wheel and Table Work
Roulette is built around a numbered wheel and a betting layout. Most versions use numbers from 1 to 36, divided between red and black, along with one or more green zero pockets.
The two most common wheel formats are:
- European roulette: 37 pockets, numbered 0 to 36
- American roulette: 38 pockets, numbered 0, 00 and 1 to 36
That extra double-zero pocket makes an important mathematical difference. On a standard European wheel, the casino advantage on most bets is approximately 2.70%. On a standard American double-zero wheel, it is approximately 5.26%.
For that reason, players comparing roulette tables should check the wheel format before placing a bet rather than assuming every roulette game uses identical rules.
SBONOVA Roulette Rules: How a Round Is Played
The basic sequence of a roulette round is straightforward.
- Players select chips and place them on the betting layout.
- Bets can cover one number, several numbers or larger groups of numbers.
- The dealer or game system closes betting before the result is determined.
- The wheel spins and the ball settles into one numbered pocket.
- Winning bets are paid according to the listed payout for that bet type.
The objective is not to reach a particular score. Instead, each wager predicts where the ball will land or which category the winning number will belong to.
Inside and Outside Bets
Roulette wagers are normally divided into inside bets and outside bets.
Inside bets cover individual numbers or small combinations of numbers. They offer larger payouts but lower probabilities of winning.
Outside bets cover broader groups such as red or black, odd or even, and groups of 12 numbers. Their payouts are lower because more wheel outcomes are covered.
SBONOVA Roulette Bets and Standard Payouts
Understanding the betting layout is one of the most useful steps for new roulette players.
| Bet Type | Numbers Covered | Standard Payout |
| Straight Up | 1 | 35:1 |
| Split | 2 | 17:1 |
| Street | 3 | 11:1 |
| Corner | 4 | 8:1 |
| Six Line | 6 | 5:1 |
| Dozen | 12 | 2:1 |
| Column | 12 | 2:1 |
| Red/Black | 18 | 1:1 |
| Odd/Even | 18 | 1:1 |
| High/Low | 18 | 1:1 |
A straight-up bet, for example, is placed on a single number. If that exact number wins, the standard payout is 35:1.
A corner bet covers four adjacent numbers, while a six-line bet covers two neighboring rows for a total of six numbers.
Outside bets such as red or black appear close to a 50/50 proposition, but the zero pocket—or zero and double zero on an American wheel—means the probability is slightly below 50%.
SBONOVA Roulette Odds: Why Payout and Probability Are Different
Payouts are easiest to understand when compared with the actual probability of winning.
On a European wheel, a straight-up number has a 1 in 37 chance of winning, or about 2.70%. However, the payout is 35:1 rather than 36:1. That difference creates the standard house advantage.
On an American wheel, a single-number bet has a 1 in 38 chance of winning, or about 2.63%, while still paying 35:1.
This is why a larger payout does not automatically mean a more favorable bet. High-paying wagers normally win less frequently.
Example: Red or Black
European roulette contains 18 red numbers, 18 black numbers and one green zero.
A red bet therefore wins on 18 of 37 possible outcomes, not 18 of 36. American roulette adds a second green pocket, further reducing the probability of an even-money bet winning.
Players researching roulette odds should always distinguish between payout, probability and house edge.
SBONOVA Roulette Wheel Types and Special Rules
Not every roulette table follows exactly the same format, so checking the game information before betting is useful.
European Roulette
European roulette uses a single zero and 37 total pockets. It generally offers a lower standard house edge than the double-zero American format.
American Roulette
American roulette contains both 0 and 00, creating 38 possible outcomes. The additional green pocket changes the probability of every standard wager.
French Roulette Rules
Some single-zero roulette games may offer special rules such as La Partage or En Prison.
With La Partage, qualifying even-money bets may return half of the stake when the ball lands on zero. Where this rule applies, the effective house advantage on those qualifying bets can fall to around 1.35%.
Rules can vary by individual game, so players should check the roulette information panel or game rules rather than assuming these features are available.
SBONOVA Roulette Strategy: Practical Points Before Betting
No betting pattern can change the underlying probability of where the roulette ball will land. Previous results also do not make a particular number “due” on an independent spin.
Useful habits instead focus on understanding the game:
- Check whether the wheel uses single zero or double zero.
- Review minimum and maximum table limits before betting.
- Learn the difference between inside and outside bets.
- Check special rules such as La Partage when available.
- Decide on a spending limit before starting.
- Avoid increasing bets simply because several previous spins lost.
- Treat previous spin history as historical information, not a prediction of the next result.
Systems that repeatedly double or adjust wagers can change how quickly bet sizes grow, but they cannot remove the mathematical house advantage.
SBONOVA Roulette on Mobile: What Players Should Check
Mobile roulette follows the same core betting principles as desktop play, but screen layout becomes more important.
Before placing a wager, make sure you can clearly see:
- Selected chip value
- Numbers covered by the bet
- Total stake
- Betting limits
- Wheel format
- Payout information
- Game-specific rules
On smaller screens, accidentally tapping a neighboring number or changing the chip denomination can alter the intended wager. Reviewing the bet summary before betting closes helps reduce simple input mistakes.
Players who are unfamiliar with an interface should first learn where the table rules and betting history are displayed.
SBONOVA Roulette FAQ: Common Questions for 2026
What is the difference between European and American roulette?
European roulette normally has 37 pockets, including one zero. American roulette has 38 pockets, including zero and double zero. The additional pocket gives standard American roulette a higher mathematical house advantage.
What is the highest standard roulette payout?
A straight-up bet on one number normally pays 35:1. It also has one of the lowest probabilities of winning because only one pocket is covered.
