Roulette looks deceptively simple. You place chips, a ball drops, and a number wins. Yet the layout hides a two-tier system: inside bets that pay big on narrow odds, and outside bets that pay modestly but land far more often. Understanding that split , and the house edge attached to each , is the difference between playing blind and playing with structure. This review breaks down every wager on a standard Australian wheel, with the maths that sits behind each one. For more details, visit click here.
Inside Bets: Higher Payouts, Narrower Coverage
Inside bets sit on the numbered grid itself. A straight-up bet on a single number pays 35 to 1 and covers 2.7% of a single-zero wheel. Splits cover two numbers at 17 to 1, streets cover three at 11 to 1, and corner bets cover four at 8 to 1. The six-line wager on two adjacent rows returns 5 to 1.
What surprises most newcomers is that the expected value barely shifts across these options. On a European wheel with one zero, every inside bet carries a house edge of 2.70%. The payout shrinks as your coverage grows, so the maths stays remarkably consistent. Australian players should note that the double-zero American layout pushes that edge to 5.26% , a near-doubling of the house’s cut for identical gameplay.
Inside bets suit players chasing variance. A straight-up punt at 35 to 1 will lose far more often than it wins, but the upside is real. Treat these as entertainment wagers with a capped budget rather than a route to steady returns.
Outside Bets: Better Odds, Modest Returns
Outside bets line the perimeter of the layout. Red or black, odd or even, and high or low each cover 18 numbers and pay even money. Dozens and columns cover twelve numbers at 2 to 1. These wagers win roughly 48.6% of spins on a single-zero wheel, which is why they anchor most conservative strategies.
The trade-off is obvious: frequent small wins in exchange for smaller payouts. Over a long session, the 2.70% edge grinds away at your balance regardless of which outside bet you choose. The key advantage is session longevity , your bankroll stretches considerably further on even-money bets than on straight-ups.
Many Australian players pair outside bets with a progression system such as Martingale. Be cautious. Doubling after a loss escalates stakes quickly, and table limits , typically capped between AUD 1 and AUD 500 on most platforms , will halt the sequence before it recovers.
Comparing the Core Wagers at a Glance
| Bet Type | Numbers Covered | Payout | House Edge (Single Zero) |
|---|---|---|---|
| Straight-up | 1 | 35:1 | 2.70% |
| Split | 2 | 17:1 | 2.70% |
| Street | 3 | 11:1 | 2.70% |
| Corner | 4 | 8:1 | 2.70% |
| Six-line | 6 | 5:1 | 2.70% |
| Column / Dozen | 12 | 2:1 | 2.70% |
| Red/Black, Odd/Even | 18 | 1:1 | 2.70% |
The table tells one clear story: no bet is mathematically superior on a single-zero wheel. Choice comes down to volatility preference, not value. Always confirm which wheel variant a venue runs before staking , the difference between 2.70% and 5.26% compounds heavily over hundreds of spins.
