How first deposit bonuses work

The purpose behind a first deposit bonus is to attract new players to join a casino. 

These bonuses come in all shapes and sizes, from deposit-matched bonus money and free slot spins to a turn on the casino’s exclusive Prize Wheel. 

But first deposit bonuses all have several things in common: they are only available to new customers, and you’ll need to fund your account to claim your reward.

First deposit bonuses also come with terms and conditions. Fortunately, most casino sites' T&Cs are easy to understand once you learn the lingo. 

Wagering requirements are the number of times you must wager your bonus before withdrawing any remaining winnings as cash. 

The average wagering requirements in the UK are around 35x, though some casino apps may offer lower. 

There will also be an expiry date within which you must complete the requirements, a table that details each game contribution, a minimum withdrawal, a maximum win cap, and so on.

First deposit bonus example

So, to give you a better idea of what you can expect at the best first deposit bonus casino sites, you may find an offer that looks something like this: '100 per cent deposit match up to £50 + 50 free spins'. 

The '100 per cent deposit match up to £50' refers to how much bonus funds the casino will reward you with when funding your account. If you deposit £20, you’ll get an additional £20 in bonus money. If you deposit £100, you’ll only get £50 in bonus money. 

You can typically spend your bonus cash on the casino’s online slot games. Some sites let you spend your bonus on table games and live dealer titles, though usually for a lower contribution to the wagering requirements. 

The '50 free spins' are free slot wagers you can spend on a specific slot or a variety of eligible games.

How to choose the best first deposit bonus

One of the most important things to look out for when choosing a bonus is the terms and conditions. A deposit match bonus up to £1,000 may look inviting, but if you have 60x wagering requirements and only a week to complete them, it’s probably not achievable for casual bettors. 

There are several things to consider that will help you pick the best first deposit bonus on the market which we've outlined below. 

Wagering requirements

First, take a look at the wagering requirements (WR). The industry average in the UK is around 35x. If you claim a 100 per cent deposit match bonus with 35x WR and deposit £10, you’ll need to wager that £10 bonus 35 times (35 x £10 = £350). 

If you pick a bonus with 60x WR, you’ll have to wager £600 (60 x £10) before you can withdraw. The lower the requirements, the less you’ll need to spend to turn it into withdrawable cash, and the more you may have remaining at the end.

Expiry dates

Next, check out how long you’re given to complete these requirements. Some gambling sites will allow 30 days, while those with less flexible terms and conditions may give you just a week (or sometimes less). 

If a bonus has slightly higher wagering requirements, it could still be achievable with a month-long expiry date. However, if a bonus has both high wagering requirements and a short expiry date, it’s best to keep searching. 

Casino game contributions

Are you happy to spend your bonus spinning the reels of the latest slots, or would you rather place your bets at a roulette or blackjack table? Most first deposit bonuses centre around slots, so finding a bonus that caters to table game players is less common. 

Slots usually contribute 100 per cent towards the wagering requirements, and while some casinos are more forthcoming than others, table games like blackjack, poker, and roulette typically contribute between 0-10 per cent. 

That said, it is possible to find first deposit bonuses that focus on classic casino card and table games. Many casinos with a large library of table games will allow as much as 50-75 per cent WR contribution for blackjack and roulette. 

What’s more, some casinos will offer an additional welcome bonus that’s exclusively for use on live dealer games. These offers work the same way as a regular deposit bonus, the difference being that you can wager on tables that are streamed in real time from studios worldwide.

Tips for maximising first deposit bonuses

First deposit casino bonuses give players the perfect opportunity to boost their bankroll and kick-start their online gaming adventure with a bang. To ensure you take full advantage of these offers, check out our top tips below. 

High RTP games

The Return to Player (RTP) tells you how much a casino game will pay back to players on average over time. So, higher RTP games theoretically return more of your bets than titles with a lower RTP.

Sure, the RTP is only an average. Slots and table games are games of chance, meaning wins aren’t guaranteed, and there is no way you can influence the outcome. But since games with higher RTPs provide better odds of winning (hypothetically), you should stick to these titles when working to fulfill the wagering requirements. 

Stick to slots

Something to avoid when wagering with your first deposit bonus is playing games that count very little (or nothing) towards the wagering requirements. 

More often than not, table games are either excluded from the bonus or will contribute around 10 per cent towards the requirements. This means you’ll have to wager 10 times more on table games than on slots, which usually contribute 100 per cent. 

Unless it’s a bonus specifically focused on table or live dealer games, it’s best to stick to online slots. 

Shop around

One final piece of advice to help you maximise your first deposit bonus is to shop around before making a real money commitment. 

There are dozens of UK online casinos boasting fair and generous deposit bonuses, but there are also dozens offering bonuses with unattainable conditions. 

If you follow the advice on this page and shop around at a few of our recommended first deposit bonus casino sites, you’re sure to find an offer that suits your style. Just make sure you’re also happy with the casino itself.

First deposit bonus payment methods

You can make your first deposit and claim your bonus using a range of popular UK payment methods, including:

• Visa
• MasterCard
• PayPal
• Skrill
• Neteller
• Paysafecard
• Pay by Mobile
• Apple Pay
• GPay

Most casino sites accept the above payment methods, and you should also take into consideration the best bank transfer casino sites that provide one of the safest deposit types.

Be aware that some casinos may exclude Neteller or Skrill from the list of eligible payment methods for a bonus. Remember to check the T&Cs before claiming a bonus to ensure your preferred banking option is available.

Be gamble aware

Online casinos can be addictive so it's important to stay in control of your gambling.

Enjoy our recommended list of the best first deposit bonus casinos responsibly with these tips:

1. Set Limits: Establish a budget before playing
2. Take Breaks: Maintain a healthy balance by enjoying breaks
3. Self-Exclusion: Consider this option if you become concerned
4. Recognise Signs: Be aware and seek help if needed

All licensed online casinos must give users the option to self-exclude, which should be utilised the moment a customer realises their gambling has become problematic.

• GamCare

• NHS
