Red Door Roulette is a European roulette game from Evolution Gaming that adds a bonus round to the usual spin. If you searched for it alongside William Hill, you want to know how the game works and what to look for before you play.
The key detail is the feature. A European roulette spin can trigger a bonus round in which the player picks one of several red doors that hide prizes. The rest of the game is ordinary single-zero roulette, with an RTP of 97.3%.
Roulette variants and where Red Door fits
Roulette is sold in several common variants. European roulette has a single zero and 37 pockets. American roulette adds a double zero for 38 pockets, which raises the house edge. French roulette uses the single-zero wheel with its own table layout and extra rules on even-money bets. Many games from providers add side features to one of these, and Red Door Roulette is a European-wheel game with a bonus round.
The wheel and the bets work as in standard roulette, and the red door round is the part that sets this game apart.

How a round works
You place chips on the layout before the wheel spins. Inside bets cover single numbers or small groups of numbers, such as a split or a street. Outside bets cover larger areas, such as red or black, odd or even, or a dozen. Smaller coverage pays more when it lands, and larger coverage pays less, which is why the numbers balance out over many spins.
With one zero on the wheel, the house keeps a small edge on every bet. The RTP for this game is 97.3%, which is a long-run average across all spins rather than a promise for a session.
The red door feature sits on top of this. A European roulette spin can trigger a bonus round in which the player picks one of several red doors that hide prizes. The prizes are decided by the game, so you pick a door, but you cannot influence what it hides.
Betting systems, such as doubling after a loss, do not change any of this. Each spin is independent, so a system only changes how fast you spend your balance.

RNG version or live dealer
An RNG roulette game uses a random number generator to decide each result, so rounds are quick and you control the pace. A live dealer table is streamed from a studio, with a real wheel and a dealer, and rounds follow a betting window set by the table. Our live casino page covers how live tables differ in practice.
For a feature game like Red Door Roulette, check how a round is presented before you stake anything, since the bonus round can change what you see on screen.
Practical points
Read the paytable and the feature rules before your first spin, and choose a stake you are comfortable losing. Check the table or game limits, since they differ between games. Set a deposit limit before you start, and stop when it is reached. If you play on a phone, the mobile version page explains what to expect.
