Roulette uses a numbered wheel and a betting layout where players can bet on single numbers or larger groups of outcomes. The basic idea is simple, but different bet types and wheel variants have different probabilities and payouts.
The roulette wheel
Roulette variants differ partly by the number of zero pockets. That detail changes the mathematical profile of the game and matters more than cosmetic differences between tables.
Always check the exact wheel and rule panel before betting.
Inside bets
Inside bets are placed in the numbered section of the layout. Common examples include:
- straight up on one number
- split on two neighbouring numbers
- street on a row of numbers
- corner on four numbers
- line bets covering a larger adjacent group
The fewer numbers a bet covers, the higher the usual payout and the lower the probability of a hit.
Outside bets
Outside bets cover broader groups such as:
- red or black
- odd or even
- low or high numbers
- dozens
- columns
These bets hit more often than a single-number wager but pay less.
Straight up
A straight-up bet covers exactly one number. It has one winning pocket and a correspondingly larger payout than broader bets.
Split, street and corner
A split covers two adjacent numbers. A street covers a row, while a corner covers four numbers meeting at one point on the layout.
The exact placement rules should be visible in the table help section.
Red/black and odd/even
These familiar outside bets cover large parts of the wheel, but the zero pocket or pockets are not part of the ordinary red/black or odd/even groups. That is why they are not exact 50/50 bets.
Dozens and columns
Dozen bets divide the main number field into larger groups. Column bets follow the vertical columns of the layout. They sit between single-number bets and the broadest outside bets in both coverage and payout.
European and American roulette
The best-known difference is the number of zero pockets. An additional zero changes the probabilities and house edge.
Two tables can therefore look almost identical while having different mathematical characteristics.
Live and digital roulette
Live roulette uses a physical wheel streamed on video. Digital roulette uses software to determine the result.
The core layout can be similar, but pace, limits and extra features may differ.
Table limits
Roulette tables can set minimum and maximum bets. Some also have separate limits for specific bet types or individual numbers.
Check both the general table limit and any field-specific restriction.
Paytable
The payout depends on how many numbers a bet covers. Use the paytable in the actual game rather than assuming every roulette version uses identical conditions.
Previous results do not predict the next spin
A history showing many red or black outcomes can be interesting, but in an independent game it does not make the opposite colour automatically more likely on the next spin.
Checklist
Before playing, check:
- roulette variant
- number of zero pockets
- inside and outside bets
- payout table
- minimum and maximum bets
- special table rules
- live or digital format
Conclusion
Roulette becomes easier to compare when single-number bets, inside bets and broader outside bets are treated separately. Wheel structure, zero pockets, table limits and the paytable define the actual game more clearly than recent result history.
