How does a casino bonus work?

If you are new to the online casino world you’re probably wondering why a casino gives you free money to play with. Casino bonuses are a clever marketing strategy used to entice players to make their first deposit, in the hope that they will continue playing. Before claiming a casino bonus it’s important to understand the components of the offer which are: the minimum turnover required to withdraw your funds (also called wagering requirements), the game weight and complete by date.

Why play with casino bonus?

There are a few key reasons why some player chooses to play with a bonus. New to the casino world it’s a great opportunity to increase your funds and find your favorite game. Hunting a jackpot!
