First, you need to figure out your expected winnings from your free spins: Average Return = Spin Value × Number of Spins × RTP Then, calculate the average cost of completing the wagering requirements. Expected Loss = (1﹣RTP) × Average Return × Wagering Requirements Finally, you take the average cost away from your expected winnings to arrive at the overall bonus value. This may sound complicated, so let’s have a look at an example. Example: You receive 100 free spins with an individual value of £0.10. The spins can only be used on a slot with a 95% RTP rate and come with 15x wagering requirements.

100 Free Spins No Deposit

The first part of our calculation requires us to calculate our average return from these 100 spins: Average Return = £0.10 × 100 × 0.95 = £9.50 Next, we take that average return and calculate how much we expect to lose while clearing the wagering requirements: Expected Loss = (1﹣0.95) × £9.50 × 15 = £7.13 Finally, we take the expected loss away from the average return to get the overall bonus value: Bonus Value = £9.50﹣£7.13 = £2.37 As you can see, there is a significant difference in the calculated value, despite the two bonuses being the same. Remember, this equation works out the average rate of return and does not guarantee that you will receive a positive return. When performing this calculation, you may arrive at a negative number for the bonus value. This means that, on average, you will not be able to clear the wagering requirements with your expected winnings. That being said, you may still be lucky enough to beat the odds and clear the wagering requirements, so don’t automatically write off these bonuses.

Free spins bonuses should be seen as a fun addition to your playing session, and not as a way to make money. When considering which free spins bonus to choose, one of the best ways to make your decision is to calculate the overall value of the promotion. Don’t worry; even if maths gives you nightmares, we’re here to break it down in a way that’s easy to understand and calculate on your own. The calculation of your bonus multiplies the value of 1 spin by the number of free spins you receive to give you the overall bonus value. Example: You receive a 100 free spins promotion where each spin is worth £0.10.

What is a free spins on deposit promotion?

To calculate the value of the bonus, simply multiply the value by the number you receive, which is 100. Performing this calculation gives you an overall bonus value. While the previous value calculation gives you a simple idea of the bonus’s value, it doesn’t paint the full picture. Wagering requirements greatly affect the amount of money you can expect to receive from your bonus and must be factored into the arithmetic. For a more exact estimate, you can perform a basic expected value (EV) count. There are plenty of casinos granting bonus spins on Big Bass Bonanza, including Spin Genie.

Once you have cleared the wagering requirements, any bonus winnings over the cap will be removed from your account as the funds are transferred to your real money balance.

This creates a problem; with so many promotions offering spins on well-known games, it’s hard to know which is both absorbing and potentially profitable.
