How to play roulette: bets, odds and the right wheel

Roulette is the simplest casino game to play and one of the easiest to play badly. The single biggest decision โ€“ European or American wheel โ€“ is made before you place a chip, and it halves the house edge on its own.

How to play roulette: bets, odds and the right wheel

The wheel and the one choice that matters

Roulette is a wheel of numbered pockets and a ball; you bet on where the ball lands. The rules are the same everywhere, but the wheel is not โ€“ and this is the only decision that changes your odds before you bet a cent.

  • European roulette: 37 pockets (0โ€“36). House edge 2.7%.
  • French roulette: same wheel, plus rules that can halve the edge on even-money bets.
  • American roulette: 38 pockets (adds a 00). House edge 5.3% โ€“ nearly double.

Always pick European or French where you can. Choosing the American wheel is the most expensive habit in roulette.

Inside and outside bets

Bet Covers Pays
Straight up 1 number 35:1
Split 2 numbers 17:1
Street 3 numbers 11:1
Corner 4 numbers 8:1
Column / Dozen 12 numbers 2:1
Red/Black, Odd/Even, High/Low 18 numbers 1:1

Inside bets (on specific numbers) pay big but hit rarely. Outside bets (red/black, dozens, columns) pay small but win often, so they stretch your bankroll โ€“ the roulette equivalent of low volatility.

The layout: what each bet covers

The betting grid contains 1โ€“36 in three columns, plus zero and, on an American table, double zero. Inside bets sit on the numbered area; outside bets sit around it.

Bet Numbers covered European chance Profit on A$5 win
Straight up 1 1/37 (2.70%) A$175
Split 2 2/37 (5.41%) A$85
Street 3 3/37 (8.11%) A$55
Corner 4 4/37 (10.81%) A$40
Six line 6 6/37 (16.22%) A$25
Dozen or column 12 12/37 (32.43%) A$10
Red/black or odd/even 18 18/37 (48.65%) A$5

The payout shown is profit; the original A$5 stake is also returned. Larger coverage creates more frequent wins but smaller payouts. On a standard European wheel, every listed bet retains the same 2.70% house edge because the payouts scale with the number of covered pockets.

Zero is why an even-money bet is not truly 50/50. Red covers 18 pockets and black covers 18, but the green zero creates the 37th losing result for both. On an American wheel, 00 adds another losing pocket without increasing the 1:1 payout.

How the house edge hides in the payouts

A straight-up number pays 35:1, but with 37 pockets the fair payout would be 36:1. That missing unit, spread across every bet type, is the 2.7% house edge. Every roulette payout is set just below the true odds in the same way โ€“ which is why no combination of bets can escape the edge.

The French-wheel bonus

On a French wheel, look for the โ€œLa Partageโ€ or โ€œEn Prisonโ€ rule. When the ball lands on zero, these refund half your even-money bet (or hold it for the next spin). That single rule cuts the house edge on red/black and similar bets from 2.7% to just 1.35% โ€“ the best odds in roulette, and worth seeking out.

La Partage normally applies only to red/black, odd/even and high/low. It does not halve the edge on a straight-up number, dozen or column. Read the table rules because not every game marketed as French roulette implements both special rules in the same way.

European versus American in A$

The extra 00 looks like one small change, but it almost doubles the mathematical cost:

Wheel Pockets RTP House edge Expected cost per A$1,000 turnover
French, even-money with La Partage 37 98.65% 1.35% A$13.50
European single zero 37 97.30% 2.70% A$27
American 0 and 00 38 94.74% 5.26% A$52.60

These are long-run expectations, not predictions for one session. The comparison shows why choosing the wheel matters more than choosing a favourite number. A player can make exactly the same red/black bets and face nearly twice the theoretical cost simply by using the American layout.

Some games add a third zero or unusual multiplier features. Do not assume the familiar roulette name carries familiar odds; check the pocket count and rules before betting.

Betting systems: the honest truth

The Martingale (double your bet after each loss) and its cousins feel clever but change nothing. The house edge is fixed per spin, so a system only reshapes how you win and lose โ€“ lots of small wins, then one big loss that wipes them out. Table limits and a finite bankroll guarantee the system eventually fails. Enjoy them as a way to structure play if you like, but never as a way to beat the game.

A Martingale example

Starting at A$5, six consecutive losses require bets of A$5, A$10, A$20, A$40, A$80 and A$160. Before the next spin, A$315 has already been lost; continuing requires A$320 to chase an eventual A$5 profit. Seven or eight losses are not impossible, and the zero loses an even-money colour bet just like the opposite colour.

The Fibonacci and Dโ€™Alembert systems increase stakes more slowly, but they still cannot change the probability or payout. A flat A$5 bet and a structured sequence face the same edge on every dollar of turnover. The sequence only changes the size and timing of the swings.

Combining bets does not cover the edge

Placing chips on red and several black numbers can make the layout feel protected, but every chip remains a separate negative-expectation bet. Covering more pockets raises the chance that something wins while reducing the net profit or creating outcomes where the winning chip does not recover all losing stakes.

For example, betting A$5 on red and A$5 on black guarantees a A$5 loss when zero appears and otherwise returns no profit: one colour wins A$5 while the other loses A$5. Adding zero costs another stake and still does not create a positive expectation because the payouts are below fair odds.

Live dealer, RNG and auto roulette

Live roulette uses a physical wheel streamed from a studio. It offers a social pace and visible spin, but limits may be higher and seats can have betting timers. RNG roulette generates the result digitally and usually plays faster with lower minimums. Auto roulette uses a physical automated wheel without a dealer.

The format does not change the basic edge if the wheel and payouts are identical. Speed does change turnover: an RNG game can produce far more spins per hour than a live table, increasing the expected cost even with the same 2.70% edge.

Check the result history only as a record of previous spins. A run of black outcomes does not make red more likely next; the wheel has no memory. โ€œHotโ€ and โ€œcoldโ€ number boards are entertainment, not predictive tools.

A sensible way to size roulette bets

Choose the total amount you are prepared to spend, divide it by the approximate number of spins you want, and treat that as the maximum total stake per spin. With A$60 for 30 spins, the planning figure is A$2 per spin before any returns. If the table minimum is A$5, that table does not fit the plan.

Outside bets create a steadier experience but do not improve the standard European edge. Inside bets create bigger swings. Pick the pattern for entertainment, keep the stake fixed, and stop at the pre-set time or loss limit rather than changing the plan after a run.

Common roulette mistakes

  • choosing an American or triple-zero wheel without checking the pockets;
  • treating red/black as a true 50/50 outcome;
  • believing previous spins affect the next result;
  • increasing stakes to recover a sequence of losses;
  • confusing a high hit rate with a lower house edge;
  • using turbo play until turnover becomes invisible.

Roulette in one line

Pick the European or French wheel to halve the edge, use outside bets for longer play and inside bets for big payouts, know that every payout hides the 2.7% edge, and treat betting systems as entertainment, not strategy. If gambling stops being fun, call Gambling Help Online on 1800 858 858.

Frequently asked questions

What is the difference between European and American roulette?

European roulette has a single zero (37 pockets) and a house edge of 2.7%. American roulette adds a double zero (38 pockets), which raises the house edge to 5.3% โ€“ nearly double. Always choose European, or French, where it is offered.

What is the best bet in roulette?

There is no bet that beats the house edge, but even-money bets (red/black, odd/even, high/low) give the most playing time because they win almost half the time. On a French wheel, the "La Partage" rule refunds half your even-money bet when zero hits, cutting the edge to 1.35%.

Do roulette betting systems work?

No. Systems like the Martingale (doubling after a loss) do not change the house edge โ€“ they just reshape your wins and losses. They produce frequent small wins and occasional large losses, and table limits stop you doubling forever. No system makes roulette profitable over time.

What does a straight-up bet pay?

A straight-up bet on a single number pays 35 to 1. Because there are 37 numbers on a European wheel (including zero), the true odds are 36 to 1 โ€“ that gap is exactly the house edge. All roulette payouts are set slightly below true odds the same way.

Is online roulette fair?

At a licensed casino, yes. RNG roulette is independently tested for randomness, and live-dealer roulette uses a real physical wheel streamed to you. Stick to casinos with recognised licensing, and prefer live or European tables for the best experience and odds.
