This is a novel idea and it has just been released today at Riverbelle Casino.
Basically if you are not already a member of the RiverBelle Casino then you should visit their special Bonus Wheel page to try your luck.
You will be given 3 free spins of the wheel and can claim your prize at any time (so if you happen to get $200 Free on the first spin claim it straight away!).
The wheel has 8 possible outcomes per spin you could either win an amount ($200, $150, $100 or $50) or you could lose your winnings, or you could win another free spin.
RiverBelle Casino is one of the oldest Microgaming powered casinos and is very well respected through out the industry with an excellent reputation for looking after its players well. It will then come as no suprise that RiverBelle Casino is ECOGRA approved and although it does accept US players (with a 100% match bonus on first deposit of buy $55 get $55 Free), this casino is really best geared up for UK Players.
