How to Complete The Bonus Wagering

First, you have to use the spins and bonus funds on eligible games. After that, you must calculate the total wagering amount based on your initial deposit and bonus. Here’s an example:

You deposit £20 and get a £40
The 30x wagering applies to the sum of your deposit and bonus
So, you will have: 30x (20+40) = 1800
You must wager a total of £1800

To keep track of your wagering, we suggest checking the promotional section of your account.

Our Verdict on The Prime Slots Welcome Bonus

Our experts tested this bonus and were impressed by what it offers. As a new player, you can get both bonus funds and spins, which you can use on multiple slots and game types. Yet, remember that the spins can only be used on Starburst. To view the full list of compatible titles, we recommend checking the casino’s terms and conditions. Other than that, the wagering of 30x is reasonable and you can easily complete it if you have some gambling experience.
