Live roulette streams a real wheel and a dealer, and you place bets on a digital layout. The game is easy to start and has a lot of bet types, so it is worth knowing how the layout shapes the odds. This guide covers wheel types, bet categories, the logic of payouts and the checks to make in the GT99 live lobby, where limits and tables are displayed.
The wheel and the zero
A European wheel has numbers one to thirty-six plus a single zero. An American wheel adds a double zero. Why does this matter? The zero pockets are the source of the house edge. A bet on a single number pays thirty-five times the stake, but there are thirty-seven pockets, not thirty-six, so the payout is slightly below the true odds. A second zero widens that gap.
So, when you have a choice, a single-zero wheel is the better layout for the player. The table header or the game rules state which wheel is used.
Inside and outside bets
Inside bets are placed on the numbers themselves. Outside bets cover large groups.
| Category | Examples | Hit frequency | Payout |
|---|---|---|---|
| Inside | Straight number, split, street, corner | Low | High |
| Outside | Red or black, odd or even, high or low | Close to half | Even money |
| Outside group | Dozens, columns | About a third | Two to one |
Why payouts follow probability
Payout size is tied to how unlikely a bet is. A straight-up bet covers one pocket and pays a lot; red or black covers about half the pockets and pays even money. Each offers the same edge on a single-zero wheel, apart from special rules on even-money bets that some tables use when zero lands. Combining bets does not alter the edge; it only changes how your wins are distributed.
Common mistakes
Several beliefs cause losses.
- Thinking a colour is due after a run. The wheel has no memory.
- Doubling stakes after a loss, which can reach table limits within a few rounds.
- Covering many numbers with small bets and assuming that reduces risk. It lowers volatility but not the edge.
- Ignoring the zero rules at the table.
Where to continue
Read gambling myths, tested against the maths for the gambler fallacy, and compare with blackjack, where your decisions can change the edge. For session control see tracking what you spend. The live casino hub lists every table guide on this site.
Reading the table interface
The layout displays chips, a countdown and a history of recent numbers. Use the countdown to confirm bets before it ends, because late bets are rejected. Treat the history as decoration. If a bet is accepted, the balance should drop at once; if it does not, check for a network problem before repeating the action.
