The guys at Boyle Games have a special promotion for roulette players. Simple place a minimum of 10 bets on European Roulette on the Games site (not casino). If you lose your money, they will refund up to £/€20 within 24 hours.
This is different to most other bonuses as the cashback refund is not subject to any wagering requirements. You can simply withdraw your cashback.
The roulette game is powered by Realistic Gaming and is quite realistic in terms of its graphics. The bet stakes are 20p on the inside and £1 or euro on the outside. Thats just like if you were to go in to a Boyle Sport Bookies and play there.
