Key Bet Roulette is a progressive cash pot style roulette game found on all Coral and Ladbrokes fixed odds betting terminals. Originally there was just the one version of the game, but due to the high stakes of the first one, a lower stake Key Bet game was also installed on the same FOBT’s alongside the original.
The playing methods and odds are exactly the same for both versions of the game, but the lower stake Key Bet Roulette’s obviously have lower cash pot amounts, so play to your wealth with regards to which ones you decide to take on.
The interesting thing about Key Bet Roulette, is that the odds and pay-outs are identical to Extra Bet Roulette, so you may also want to refer to that guide too. It seems Extra Bet borrowed heavily from this game, changing only the graphics and a couple of bonus cash amounts.
