You should check whether the bonus is for slots, table games, or the live dealer content. Let’s say that your bonus 50 AUD has the rollover terms of 30xB attached to it, and the T&C say that slots contribute 100%, while table games contribute 30%. This means that every dollar you roll over on slots counts just that – 1 dollar towards the wagering requirements, while if you decide to run this bonus though the table games, only 30 cents from each dollar contribute to the rollover terms, which means this will cost you much more to complete the terms.
