Due to the fact that this is a 300% bonus reward, it enables you to win impressive sums of money.

Typically the winnings limit is set at around £5,000.

These reload prizes can be random or tied to a specific timeframe, but the one thing that is guaranteed is that they provide you with a betting boost.

Activated Without Bonus Codes
