More about Online Roulette
Unlike traditional variants, Key Bet Roulette by Barcrest (Light & Wonder) features an extra Key Bet position on the wheel, triggering a secondary Key Bet Multiplier Wheel. If the ball lands in the Key Bet pocket, the payout multiplies your Key Bet wager.
My Take: The interface feels very much like a classic UK bookies terminal. I liked the Key Bet multiplier option, but you also need to place an extra bet for this to be active with each spin. The multiplier values range from 20x to 100x for the Pot.
Online Roulette Knowledge Box
House Edge
The built-in advantage the online game has. It is 2.70% for European wheels but rises to 5.26% for American versions.
Even Money Bet
Bets like Red/Black or High/Low that offer 1:1 payouts. These are the safest entry points for new players to manage their digital balance.
Table Limits
The minimum and maximum stakes allowed. Online RNG games often allow 10p stakes, whereas Live Dealer tables typically start at £1.
En Prison
A French Roulette rule where even-money bets are "held" for another spin if the ball lands on zero.
La Partage
A French rule where you get half your stake back on even-money bets if the ball lands on zero.
Live Dealer
A real human croupier streamed in HD. This matches the social "intent" of a real casino but requires you to place bets within a specific time window.
Non Live RNG
Roulette games that use a Random Number Generator rather than a physical wheel and dealer.
Racetrack
An oval betting area on the game layout, showing numbers as they appear on the roulette wheel. Used for placing "neighbour" or "called" bets.
Rules and Special Features
Key Bet Roulette uses a Stake button for the minimum bet amounts per spin, which are set at Low (£1), Medium (£2), and High (£10). There are no options to manually change chip or bet amounts.
The core rules follow standard European Roulette: single zero and 37 pockets, but with an added Key Bet section. Because of this bonus feature, the RTP is slightly lower at 94.74%. Bets are placed by putting chips on the board, covering individual numbers, corners, streets, or the wider outside bet areas.
Key Bet Roulette – Gameplay & Betting Options
Clicking the Neighbour Bet button will take you to the racetrack view, while the Bet On Wheel shows you the roulette wheel view, so you can use both options to set out different betting patterns.
The defining feature of this roulette variant from Barcrest is the Key Bet Bonus. If the ball lands in the yellow Key Bet pocket, the Key Bet Multiplier Wheel spins to award one of the multiplier amounts or the 100x Key Bet Pot.

Conclusion – Worth Playing Key Bet Roulette at Online Casinos?
Yes. The standard European Roulette gameplay combines well with the Key Bet features and multipliers, making this older game release comparable to newer games that use similar additions.
This variant balances traditional European gameplay with an accessible side-bet mechanic, which is simple to understand. While the 94.74% RTP is rather low in my opinion, the chase for multipliers offers a unique incentive if you’re looking to land bigger occasional payouts. However, it’s worth keeping a close eye on your bankroll due to the more complex staking options.
Heath Chesters Casino Expert
My Key Bet Roulette Tip
“While I do like the Key Bet position with the addition of multipliers, I regard it as more of a side bet option with high volatility. It doesn’t land frequently, although the potential returns of up to 100x your bet make it worth trying occasionally.”
