Roulette looks complicated from a distance , a spinning wheel, a bouncing ball, a felt layout covered in numbers. Up close, though, it rewards the patient player. Every bet you can place falls into one of two families: inside bets, which cover specific numbers, and outside bets, which cover groups of numbers. Understand those two families and you understand the game. What follows is a practical walk through the basic bets, the odds attached to each, and the house edge you are actually playing against in a United Kingdom casino.

One fact frames everything else. A single-zero wheel, common in UK land-based casinos and many online rooms, carries a house edge of 2.7% on almost every standard bet. A double-zero wheel pushes that figure to 5.26%. The difference sounds small. Over a few hundred spins it is not. Before you place a single chip, check which wheel you are playing , that one number matters more than any betting system sold online.
Outside Bets: The Bread And Butter
Outside bets sit on the outer rim of the layout and cover large groups of numbers. They pay less, but they land more often, which suits players who want a longer session from a fixed bankroll. These are the bets most UK players start with, and with good reason.
Red or black pays even money (1:1) and covers 18 numbers. Odd or even works the same way. High or low splits the numbers into 1-18 and 19-36, again at 1:1. Each of these wins on 18 of 37 pockets on a single-zero wheel , a 48.65% chance per spin. That near-coin-flip feel is why they remain the most popular bets in the room.
Dozens and columns pay 2:1. A dozen bet covers twelve consecutive numbers (1-12, 13-24 or 25-36); a column bet covers the twelve numbers stacked in one vertical line. Your chance of winning is 12 in 37, or 32.43%. Both carry the same 2.7% house edge as the even-money bets, so there is no mathematical reason to prefer one over the other. Choose on feel, not on folklore.
A note on the even-money bets: some UK rules apply la partage, which returns half your stake when zero hits on an outside bet. Where offered, it halves the house edge on those bets to roughly 1.35%. It is worth asking the dealer or checking the game rules screen before you sit down.
Inside Bets: Higher Risk, Higher Reward
Inside bets sit within the numbered grid and cover fewer numbers. They pay more, hit less, and demand a slightly steadier temperament. The straight-up bet , a single chip on one number , pays 35:1 and wins on 1 pocket in 37, a 2.70% chance. That is the glamour bet, and it is priced fairly for what it is.
The split covers two adjacent numbers and pays 17:1. The street covers three numbers in a row at 11:1. A corner covers four numbers at 8:1, and a six-line covers six numbers across two streets at 5:1. Every one of these carries the identical 2.7% house edge on a single-zero wheel. The payouts differ because the probabilities differ , the maths stays level across the board.
This is the point most beginners miss. No inside bet is “better” than another in expected value terms. A straight-up bet and a red/black bet lose you the same proportion of stake over time. What changes is variance: how violently your bankroll swings along the way. If you have £50 and want an evening’s play, outside bets will stretch it. If you have £50 and want a shot at £1,750, the straight-up is your only route.
| Bet | Numbers Covered | Payout | House Edge (Single Zero) |
|---|---|---|---|
| Straight-up | 1 | 35:1 | 2.7% |
| Split | 2 | 17:1 | 2.7% |
| Street | 3 | 11:1 | 2.7% |
| Corner | 4 | 8:1 | 2.7% |
| Six-line | 6 | 5:1 | 2.7% |
| Column / Dozen | 12 | 2:1 | 2.7% |
| Red/Black, Odd/Even, High/Low | 18 | 1:1 | 2.7% |
Staking, Limits And Playing Sensibly
UK-licensed operators are required to display table limits clearly, and they matter more than most players realise. A £1 minimum with a £500 maximum gives you room to manoeuvre; a £5 minimum on a £100 bankroll gives you twenty spins and no more. Set a session budget before you open the table, treat it as spent, and stop when it is gone.
Keep your bets simple at first. A spread of three or four outside bets plus the occasional straight-up on a favourite number gives you coverage without chaos on the layout. Track what you stake , the Gambling Commission’s own data consistently shows that players who set deposit limits enjoy the game more and regret it less. Roulette is a game of fixed odds, not a puzzle to be solved. Play the wheel you understand, at stakes you can afford, and the basic bets will serve you well.
