12. Why do some sites offer such huge bonuses?

The competition in the gambling industry has grown to extreme heights. The presence of so many means everyone is racing to outdo the other. As part of this race, the gaming sites offer various incentives to get the bulk of the players on their side.

Furthermore, all licensed UK gambling sites are required by law to keep your funds safe in a separate account, ensuring they are protected even if a casino goes bankrupt
