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 €30.
Mid Rollers will use an average player bet size (€0.54/spin) and an average deposit value of €50.
High Rollers will use a large player bet size (€1.98/spin) and a large deposit size of €100.
Super High Rollers will use a large player bet size (€1.98/spin) and a large deposit size of €200.
The value of the complimentary spins will be assessed first and added on to the value of the bonus at the end of simulation.
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 Mason Slots complimentary spins we have 100 complimentary spins on Rise of Merlin with a value of €0.10/spin. That’s a total of 100×0.10 = €10 of wagers. The average win from the complimentary spins will simply be the total wagers multiplied by the RTP. So 10×0.966 = €9.66.
We then take the €9.66 win and assess the impact of the wagering requirement. The wagering requirement will be 9.66×15 = €144.90. We then conduct the following simulations for Low, Mid and High Roller play:
So the free spin value is €6.18 when placing minimum bets.
Free spin value is €4.58.
Free spin value is €2.85.
The structure of the Mason Slots bonus is of the straightforward kind where bonus terms apply from the moment of deposit. This makes for a very straight forward simulation that requires only one step.
Low Roller Bonus
Using a deposit of €30 with a bonus of €30, with a wagering requirement of 30×40 = €1200 and a bet size of €0.09/spin we get the following results:
So the value of the bonus is -€2.41.
Adding the value of the complimentary spins we get -€2.41 + €6.18 = €3.77.
Mid Roller Bonus
Using a deposit of €50 with a bonus of €50, with a wagering requirement of 50×40 = €2000 and a bet size of €0.54/spin we get the following results:
So the value of the bonus is €9.89.
Adding the value of the complimentary spins we get €9.89 + €4.58 = €14.47.
High Roller Bonus
Using a deposit of €100 with a bonus of €100, with a wagering requirement of 100×40 = €4000 and a bet size of €1.98/spin we get the following results:

Adding the value of the complimentary spins we get €31.95 + €2.85 = €34.80.
