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 (€2.97/spin) and a large deposit size of €100.
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.
Due to the win restriction on the first 100 spins we have to sim these spins separately.
In the case of the 21.com Casino complimentary spins we have 100 complimentary spins on Vampires vs Wolves 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 10×0.9649 = €9.65.
We then take the €9.65 win and assess the impact of the wagering requirement. The wagering requirement will be 9.65×50 = €482.50.
Then the second group of spins is 900 complimentary spins on Vampires vs Wolves with a value of €0.10/spin. That’s a total of 900×0.10 = €90 of wagers. The average win from the complimentary spins will simply be the total wagers multiplied by the RTP. So 90×0.9649 = €86.84.
We then take the €86.84 win and assess the impact of the wagering requirement. The wagering requirement will be 86.84×50 = €4342.
Adding the value of the two sets of complimentary spins together we get €4.73 + €13.59 = €18.32.
Adding the value of the two sets of complimentary spins together we get €6.31 + €37.16 = €43.47.
Adding the value of the two sets of complimentary spins together we get €4.78 + €57.48 = €62.26.
The structure of the 21.com Casino 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 50×30 = €1500 and a bet size of €0.09/spin we get the following results:
So the value of the bonus is -€6.30.
Adding the value of the complimentary spins we get -€6.30 + €18.32 = €12.02.
Mid Roller Bonus
Using a deposit of €50 with a bonus of €50, with a wagering requirement of 50×50 = €2500 and a bet size of €0.54/spin we get the following results:
So the value of the bonus is €5.37.
Adding the value of the complimentary spins we get €5.37 + €43.47 = €48.84.
High Roller Bonus
Using a deposit of €100 with a bonus of €100, with a wagering requirement of 100×50 = €5000 and a bet size of €2.97/spin we get the following results:
So the value of the bonus is €33.34.
Adding the value of the complimentary spins we get €33.34 + €62.26 = €95.60.
