Terms and Conditions

The Spin Slots Casino Welcome bonus currently consists of a bonus of 100% up to £100 plus 10 complimentary spins on Cleopatra.

The minimum deposit that will trigger the bonus is £10.

This bonus has a wagering requirement of 30x(deposit+bonus) for the deposit bonus and 30xwinnings for the complimentary spins.

The bonus is structured so that only wagering with bonus funds, which are stacked beneath the deposited funds, counts towards the wagering requirement. This also means that bonus restrictions, do not apply while you are wagering with your deposited funds. In other words as long as you are only using deposited funds you can withdraw at any time you like.

There is no maximum bet term associated with this bonus.

The maximum allowed win with this bonus, including from the complimentary spins, is 4xbonus.

The bonus is cashable.

Bonus and associated winnings will expire after 28 days if the wagering requirements are not completed.

Simulations

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 (£4.95/spin) and a large deposit size of £100.

Super High Rollers will use a large player bet size (£9.99/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

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 Spin Slots Casino complimentary spins we have 10 complimentary spins on Cleopatra with a value of £0.20/spin. That’s a total of 10x0.20 = £2 of wagers. The average win from the complimentary spins will simply be the total wagers multiplied by the RTP. So 2.00x0.9502 = £1.90.

We then take the £1.90 win and assess the impact of the wagering requirement. The wagering requirement will be 1.90x30 = £57.00. We then conduct the following simulations for Low, Mid and High Roller play:

Low Roller

So the complimentary spin value is £0.56 when placing minimum bets.

Mid Roller

Complimentary spin value is £0.29.

High Roller

Complimentary spin value is £0.16.

 

 

Deposit Bonuses

Due to the structure of the Spin Slots bonus where wagers with deposited funds do not count towards the wagering requirement the bonus has to be assessed in two parts: the pre-bonus wagering and the value of the bonus. Once we have conducted these simulations we work out the value of the bonus as follows:

[Expected Loss from pre-bonus play] -([Value of the bonus]x[Chance of using the bonus]) = [Average Expected Value for the bonus]

Low Roller Bonus

Using a deposit of £30 with a bonus of £30, with a wagering requirement of 60x30 = £1800, a withdrawal target of 5xdeposit and a bet size of £0.09/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus:

Average Expected Value for the bonus = -£22.88 + (£7.11x0.9562) = -£16.08

Adding the free spin value on to the result above we get -£16.08 + £0.56 = -£15.52.

Mid Roller Bonus

Using a deposit of £50 with a bonus of £50, with a wagering requirement of 100x30 = £3000, a withdrawal target of 5xdeposit and a bet size of £0.54/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus:

Average Expected Value for the bonus = -£18.31 + (£13.67x0.8952) = -£6.07

Adding the free spin value on to the result above we get -£6.07 + £0.29 = -£5.78.

High Roller Bonus

Using a deposit of £50 with a bonus of £50, with a wagering requirement of 100x30 = £3000, a withdrawal target of 5xdeposit and a bet size of £4.95/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus:

Average Expected Value for the bonus = -£5.40 + (£7.73x0.8977) = £1.54.

Adding the free spin value on to the result above we get £1.54 + £0.16 = £1.70.

Super High Roller Bonus

Using a deposit of £50 with a bonus of £50, with a wagering requirement of 100x30 = £3000, a withdrawal target of 5xdeposit and a bet size of £9.99/spin we get the following results:

We now do a quick sum to calculate the overall value of the bonus:

Average Expected Value for the bonus = -£5.40 + (£5.92x0.8977) = -£0.86.

Adding the free spin value on to the result above we get -£0.86 + £0.16 = -£0.70.
