William Hill casino recently switched to a unique bonus scheme which they call the "unlimted new player bonus" and "unlimited monthly bonus". The bonus is determined solely by the amount you wager. It is a tiered scheme where you are paid a certain amount each time your wagerings pass a predetermined threshold. For example, once you wager £500 on their monthly bonus you earn a bonus of £25, then when your wagerings pass £5000, you earn another £25, making £50 in total.
