Our review will provide a value for Low Rollers, Mid Rollers and High Rollers. Each category will use the same slots game (Thunderstruck) for accurate comparison.

Low Rollers will use the minimum possible bet size (€0.09/spin) and a low deposit value of €20.

Mid Rollers will use an average player bet size (€0.54/spin) and an average deposit value of €20.

High Rollers will use a player bet size (€3.96/spin) and a deposit value of €20.


Complimentary Spins

Complimentary Spins have to be assessed in two steps. Firstly the average win for the Complimentary Spins have to be established and secondly the wagering requirement has to be assessed for that average win to find how much the player will be left with on average.

In the case of the Griffon Casino complimentary spins we have 50 complimentary spins on Book of Dead with a value of €0.10/spin. That’s a total of 50x0.10 = €5.00 of wagers. The average win from the complimentary spins will simply be the total wagers multiplied by the RTP. So 5.00x0.962 = €4.81.

We then take the €4.81 win and assess the impact of the wagering requirement. The wagering requirement will be 4.81x35 = €168.35. We then conduct the following simulations for Low, Mid and High Roller play:

Low Roller

So the complimentary spin value is -€1.00 when placing minimum bets.

Mid Roller

Complimentary spin value is -€1.98.

High Roller

Complimentary spin value is -€9.14.
