Key Bet Roulette

Key Bet Roulette is an RNG-based virtual European roulette game built in HTML5 and JavaScript by Light & Wonder, played on the standard 37-pocket single-zero wheel. As a base game it carries the familiar 2.70% house edge, though here the published RTP is 94.73% (slotcatalog lists 94.74%, a rounding variation), reduced from the 97.30% single-zero baseline because of the optional side bet. It is not a live-dealer title and is mobile-optimised.

That side bet is the game's defining feature. The Key Bet is an independent wager on a dedicated pocket: as the wheel spins, sections light up showing 20x, 25x, 30x, 35x, 40x, 50x and a Pot, and if the ball lands in the Key Bet pocket you win whichever value was lit, with the Pot paying 100x stake. Bet limits run from EUR 0.20 to EUR 25.00 on single numbers, EUR 1.00 to EUR 500.00 on even-money bets, and EUR 1.00 to EUR 250.00 on the Key Bet itself.
