First deposit bonuses and a few things to consider

They say nothing in life comes for free and this certainly applies to online casino bonuses, including those you receive when you make your first deposit.

Terms and conditions are applied to all promotions and can be different for each bonus. It’s important to read them and understand what they mean before claiming an offer.

This is because the T&Cs can reduce the value of the bonus when you factor in things like win limits and wagering requirements.

That’s not to say a first deposit bonus doesn’t add value to your play, but being aware of the T&Cs means you know exactly what you’re getting when you claim a bonus.

First deposit bonus T&Cs to watch out for

T&Cs can be quite lengthy, so we've broken out the key terms to be aware of, what they actually mean and the impact they can have on the bonus offer.

Maximum bet - The maximum amount you can bet on a single round when using bonus cash or spins.

Cap on bonus winnings - The maximum amount you can withdraw from the bonus.

Payment restrictions - The bonus is not available when depositing with certain payment methods, usually digital wallets such as Skrill and Neteller.

Wagering requirements - How much you need to playthrough before you can withdraw your bonus or winnings as cash.

Limited game selection - The games that can and can’t be played using bonus cash and/or free spins.

Bonus expiry - The amount of time you have to use the bonus before it expires.

Minimum deposit to trigger the bonus - Most first deposit bonuses have a minimum deposit to unlock the offer, usually between £10 and £20.

Casino bonus wagering requirements explained

The wagering requirement is the number of times you have to wager the bonus amount or your winnings before you can withdraw the bonus amount or your winnings as cash.

Wagering requirements vary a lot from casino to casino. Low wagering casinos will impose playthrough requirements of between 10x and 30x, but they can be as high as 65x at some brands.

No wagering casinos impose no playthrough requirements whatsoever – although the value of the bonuses offered is usually much less, it’s your money to play with and withdraw as and when you want.

Calculating the wagering requirement on the first deposit bonus can be tricky, especially if both a deposit match and free spins are offered.

For the deposit match, the wagering requirement is usually applied to the bonus amount and with free spins, to your winnings.

This is how you would calculate each:

Deposit match:

  • Calculate the bonus amount claimed
    Multiply this by the wagering requirement

    Free spins:
  • Calculate your winnings from the free games
    Multiply this by the wagering requirement

This will give you the total amount you have to wager before you can unlock your bonus or winnings as cash

How to calculate the wagering requirement

Still not sure how it works? Here’s an example.

You’re offered a first deposit bonus that consists of a deposit match of 100% up to £100 PLUS 100 free spins with a wagering requirement of x40.

For the deposit match, you put in £100 to claim the full £100 bonus match.

Bonus: £100
Wagering requirement: x40
Amount to be wagered: £100 x40 = £4,000

For the free games, you play the spins and win £10 in bonus cash.

Bonus: £10
Wagering requirement: x40
Amount to be wagered: £10 x40 = £400

This doesn’t mean you have to deposit and lose £4,400 (the deposit match and free spins requirement combined), just that you need to cycle that value through the casino before you can unlock your winnings as cash.

There’s a growing number of first deposit bonus casino sites that don’t impose wagering requirements, so you can keep what you win.

An important word on responsible gambling

Online casino is fun and enjoyed by millions of people across the UK. But it’s important that it does stay fun and that you remain in control of your play. Because we only partner with UK-licenced online casinos, each of the brands listed on Comparasino offers the tools you need to do this.


But some of these tools might be unfamiliar and it can also be tough to determine if you, or a family member or friend, could potentially have a gambling problem. That’s why we’ve created a Safe Gaming Hub where you can find information about all the responsible gambling tools offered at online casinos, how they work and which ones might be best for you.


It also contains insights into some of the early signs of problem play to be aware of in yourself and others as well as direct access to charities and organisations that support those with problem gambling habits.
