Sign Up Deposit Offer Frequently Asked Questions

What are Free Spins?

Free spins do exactly what they say on the tin, these are spins which are completely on the house. The key things to consider when you receive free spins are the value of the spins, what game the free spins are playable on and whether or not the spins are wager-free.

Some casinos require any winnings from free spins to be wagered, meaning that you need to play through the value of any winnings a specified amount of time. You won’t catch us asking you to do that, every single free-spin you receive while you play at Slot Boss is wager-free, this means any winnings you receive go directly to your cash balance! You can find out more about wagering below.

Wagering Requirements Explained

Wagering requirements are very common in online casinos. The very basic explanation of a wagering requirement is that it’s the number of times an amount of money must be played through in order to unlock a reward.

For example your New Player Deposit Offer requires you to wager your deposit amount 50x, so if you deposited £50 and wanted to unlock the £50 cash reward, you would need to play through your £50 deposit 50 times. Some games contribute different percentages towards wagering, so it’s important to understand before you start playing, what the wagering contribution percentage is; for example for your New Player Deposit offer, slots and Slingo contribute 100% towards your wagering requirement whilst Live Casino contributes 30%, so staking £1 on a Live Casino game would contribute 30p towards wagering compared to £1 if you played a slot or Slingo game.

Can can find a breakdown of the new player Deposit Offer below:

Example Offer = Deposit £50 and wager 50x to receive a £50 cash reward

Wagering Requirement = 50x

Calculation = £50 (Cash) x 50 (Wagering Requirement) = £2500

Explanation = To withdraw any winnings from the bonus, you must wager your deposit amount 50 times. In this scenario, you must play through £50, 50 times, setting a wagering target of £2500 - once this has been reached, your £50 cash reward will be instantly available to claim from your ‘My Promotions’ page.

Don’t forget that you can always head to your My Promotions page to view your wagering progress on any bonuses that require wagering.
