How to Get a First Deposit Bonus for Slots Online

Claiming a welcome bonus for casino slots is easy, regardless of whether you want to claim a deposit offer, a free no deposit offer, or a free spins no deposit welcome bonus. Still, if you are new to online casino UK bonuses, there are a few things to keep in mind before claiming an offer for the first time at a new casino. For starters, only one sign up bonus is available per player.

Next up, you should choose only UK-licensed casino sites that reward deposits new players make. Terms apply to casinos licensed by the UK Gambling Commission to ensure they adhere to strict security standards. So, all new customers can be confident that the operator and its slot bonuses are legit at licensed UK casinos. You can play confidently knowing that you will be able to withdraw your bonus and free spin winnings.

Once you have selected a first deposit spins offer or a free no deposit bonus, you can create and verify your player account number. The next step is to open the banking cashier and make a deposit. Of course, you should check first the valid payment methods. Upon making a qualifying deposit, your welcome bonus will be awarded, and you can start to play slots with it. Although some offers may require a promo code. To recap, here are the steps to claim a first deposit slots bonus offer:

  • Step 1: Pick an online slots deposit bonus We have ranked the top 10 first deposit slots bonuses to help you choose an offer.
  • Step 2: Check the wagering requirements All bonuses come with terms conditions. You should check the wagering requirements and choose an offer that you can conveniently fulfil before the games bonus expires.
  • Step 3: Check the bonus amount Decide how much you want to deposit, paying attention to the minimum deposit and the maximum available bonus.
  • Step 4: Make a first deposit Most slot bonuses are automatically awarded upon making a qualifying deposit. Whereas some require you to enter a promo code. You should make the required minimum deposit with an eligible payment method.
  • Step 5: Start to play through your bonus You can now play online slots with your casino bonus and start to clear the wagering requirements.

Claiming an online casino bonus for new customers is simple. The more important consideration is how to pick the best deal to suit your needs. Conditions apply and offers can vary greatly. Each casino applies bonus conditions. You could find differences in the bonus amount, max bet, max win, max cash withdrawal, the percentage match, the eligible games, the wagering requirements, and various other factors. You will also find that the terms that apply to free no deposit bonuses differ even more.

Terms apply to all bonuses and it is important to always read the bonus terms and conditions before accepting any offer. You should only accept a games bonus if it comes with conditions that suit you. You should also pay attention to whether a promo code is needed to receive the offer. You should consider what type of bonus you would benefit most from and compare bonuses to find those that provide the best deal.

Wagering Requirements to Keep Track Of

All British casino bonuses come with certain terms and conditions. We advise to always read the promotional terms before accepting any welcome offers, so that you know which terms apply. Wagering requirements are a key part of the bonus terms. This expresses how many times you must play your welcome bonus through before your winnings can be withdrawn.

You will usually need to wager free spins winnings too. Keep in mind that your deposit balance is available for withdrawal at any time. Bonus funds are separate to cash funds, and bonus cash usually needs to be wagered. If you make a withdrawal from bonus money before completing wagering, you could forfeit your remaining bonus.

Each operator applies bonus playthrough requirements to their slot bonuses to ensure that you play games with your bonus. Without such conditions, new customers could simply withdraw the bonus cash and walk away. The bonus conditions also include other important terms that you should pay attention to. Here are the key slot bonus terms to check before you claim an initial deposit bonus for casino slots for the first time:

  1. Minimum Deposit Most first deposit bonuses for slots are automatically awarded when you make a qualifying deposit. Each operators applies bonus conditions to claim the offer. The minimum deposit needed to claim welcome offers usually varies from £10 – £20. So, you need to make sure you deposit at least the minimum required to qualify for the welcome bonus funds.
  2. Playthrough Always check the wagering requirements attached to an online slots deposit bonus. This expresses the number of times the casino bonus must be played through, and sometimes deposit too, to convert your bonus and free spin winnings into real cash. If you try to withdraw before completing the wagering, you will forfeit any remaining bonus funds, along with any winnings.
  3. Slot Weight You should check how much games contribute towards bonus playthrough. Slots usually contribute 100% towards bonus playthrough. Yet, some bonuses could feature different weightings for selected slots. For instance, if you play slots with 75% weighting, only 75p of every £1 wager will count towards bonus playthrough.
  4. Validity Most first deposit slots bonuses for new customers come with an expiry date and must be used within the specified time. Otherwise, the bonus expires. Consider how often you will play. And check how long is the bonus valid. Then choose an offer that will allow you to play through the bonus conveniently within the given time limits.

Types of First Deposit Bonus Offers for Slots

First deposit bonuses for slots are available the first time you make a deposit. They can come in various shapes and sizes. And terms apply to all offers. The best choice for you will depend on your budget and how frequently you play. Many welcome offers will match your initial deposit pound for pound, up to a max cash amount. So, high rollers that play responsibly could benefit from choosing offers with a high matched bonus sum.

Beginners, new customers, and low stakes casino players, on the other hand, should pay attention to the minimum deposit. Offers that match small deposits per player with bonus funds or extra spins could provide the best option. And remember that your deposit balance is available for withdrawal at any time. Additionally, wagering requirements can vary significantly from one offer to another.

Almost every casino site applies bonus wagering requirements to their offers. So, make sure you check the terms before accepting any new UK bonus. Bonus funds are separate to cash funds, and a withdrawal from bonus winnings is only permitted once wagering is completed. The lower the wagering, the more convenient the playthrough. So, slots bonuses with low wagering requirements fall into a separate category.

You will find that extra spins are a common feature of many first deposit bonus slots offers. The offer could consist entirely of free spins playable on selected games. Alternatively, some welcome offers include extra spins in addition to the games bonus funds. It’s also worth knowing that you could occasionally claim a free spins no deposit welcome bonus or a free no deposit deal. Always check the terms to see if a promo code is required to claim such offers, and to know how many times you will need to wager free spin winnings.

We’ll explore all the different types of first deposit slots bonus you could claim in the following sections. We also recommend checking our guide to the best casino bonuses in the UK to find out about all types of casino UK bonuses and offers in more detail.

100% First Deposit Slots Bonus Match

The most common type of first deposit casino bonus for slots in the UK is the 100% match bonus. With this type of offer, the operator will match your initial deposit with the same amount in bonus funds. This type of slots bonus basically doubles your initial balance. As with all bonuses, terms apply. You can usually claim only one 100% welcome bonus per player at a casino.

Most matched offers for new customers can be claimed with a minimum deposit of just £10 or £20. Yet the max bonus up for grabs can vary considerably between different bonuses. We have compared the offers currently available for UK players. And here is our top recommended 100% match deposit slots bonus:

100% First Deposit Match up to £400 on Classic Slots
Full T&Cs apply. 100% buy-in up to £400 buy-in bonus. Min £20 cash buy-in to be eligible. Offer only available on classic slot games. Max bonus £400. Max stake £2. 20x wagering requirements on total of buy-in and bonus amount. Bonus is valid for 7 days. Keep it fun - set your deposit limit.

To claim a 100% casino deposit bonus, you simply need to make a qualifying deposit, and your money will be doubled. So, if you make a first deposit of £20, you will get an extra £20 in bonus money on top. This gives you a total balance of £40 to play eligable slots. Of course, such an offer is only available for depositing players, and is not available as a free no deposit bonus. You will find that many 100% first deposit bonuses also give you extra spins as well.

In comparison, if you want to claim the maximum full bonus, you need to deposit the same amount as the max bonus. Let’s take the example of a 100% up to £400 bonus. To get the full bonus, you will need to deposit £400. This will be matched in full, giving you a balance of £800. Always keep wagering requirements in mind, and only claim a bonus that you can play through conveniently before the bonus expires. After all, some offers come with just a few days bonus validity. And keep in mind that a max bet on selected games usually applies to bonuses, as does a max win with bonus money.

200% or Higher First Deposit Match

While the 100% match is the most common type of offer, some British casino slot bonuses provide a bigger percentage match. You could claim a 200% match bonus, or even higher at some UK casinos online. However, such offers are extremely rare.

A bigger percentage match offers better returns on your deposit. However, such offers do not always provide better value. The trade-off is that these offers for new customers could come with more restrictions full of conditions. The offers could be tied to higher wagering requirements or be limited to a small selection of casino games. They could also restrict the max bet with bonus cash. Still, if you want to claim a 200% first deposit slot bonus, here is our recommended offer:

200% First Deposit Match up to £100
Full T&C apply. 18+. New players only. Up to £10 bonus credit and up to 200% first deposit match available via Feature Game. Deposit match available after first deposit. Max bonus £100. 40X wagering requirement. £10 bonus credit 7 days expiry. Deposit bonus 30 days expiry.

A 200% casino bonus offer will give you double your deposit balance with bonus money. So, if you deposit £10, you’ll get a £20 bonus, giving you a balance of £30 to play casino slots with. If you want to claim the maximum bonus, you will need to deposit half the max bonus. Taking the example of a 200% up to £100 bonus, with a £50 deposit, you would get the full £100 bonus, taking your total playing balance to £150. As mentioned, these types of offers usually come with more restrictions. So, make sure you read the promotional conditions to see which terms apply.

Low Deposit Slots Bonuses

Online casinos usually display the maximum bonus that they offer. To claim the full amount, you would need to deposit a significant amount. However, if you don’t want to deposit a lot of cash, you could still take advantage of a casino games bonus and play responsibly. Instead of looking at the maximum amount on offer, you should pay close attention to the minimum deposit with which you can claim a slot sites deposit bonus.

Many of the best online slots deposit bonus promos can be claimed with a small deposit. It is a perfect way for beginners and new customers to get started at an online casino without risking a lot of money. Making the minimum deposit to claim a slots bonus will boost your starting balance. It is also a good way to ensure you can clear wagering requirements if there is a max bet applied to bonus cash wagers. It is a great way to test whether you want to play with real money at the casino. If this sounds like the right type of offer to suit you, then here is the best low deposit online slots casino bonus in the UK:

Up to £300 + 400 Free Spins
Min Deposit:
£10
Match:
100%
Payments:
Visa, Mastercard
Full T&C apply. 18+. New players only. Up to 400(18p) free spins on first deposit, awarded over 20 days. Expires 00:00 daily. Locked to Cleopatra’s Prizes. Up to £300 deposit match. Min deposits £10. Dep1: up to 100%, Max £100. Dep2: up to 200%, Max £200. Bonus and FS winnings subject to 40x wagering requirement. Withdrawing qualifying deposit excludes player from promotion.

As with all casino bonuses and offers, you should always read the terms and conditions before accepting a low deposit offer. You should check not only the minimum deposit required to receive the bonus but also pay attention to any restrictions related to payment methods. You could find that certain payment methods such as Skrill Neteller are excluded from the offer, so make sure you choose a suitable payment method when making the first deposit. You will usually find debit card PayPal deposits valid for claiming an offer. You can be sure to find the payment restrictions full details within the bonus terms.

With a low deposit slots bonus, you could usually benefit from a 100% match bonus, free spins on selected games, extra spins, or even a higher percentage match. Although, keep in mind that a higher bonus match could come with higher wagering, and your bonus funds will be separate to cash funds until wagering is completed. We have created a guide to the best £10 deposit casino sites in the UK, where you can find even more recommended low deposit casino bonuses. Small stakes new UK players may also be interested in £5 deposit casino sites, where you can play online slots with the smallest deposits.

Free Spins on First Deposit

Free spins bonuses are popular with slots players. So, many online casinos in the UK offer free spins on selected games or bonus spins as part of their first deposit offers for new customers. Some first deposit casino bonuses offer spins free exclusively. In contrast, other offers provide free spins on Starburst, Rainbow Riches, or other popular casino slots in addition to a matched deposit. Some welcome bonus promotions even offer free spins no deposit required. Whether you are interested in bonus spins on Starburst or any other game, there are various factors to keep in mind when it comes to choosing a bonus that gives you spins free.

The number of extra spins credited to your account could depend on the deposit sum. The bonus spins could be awarded in full upon making the first deposit. In comparison, other bonus spins could be released in batches over a period of days. Plus, free spins are usually playable on selected slots and do not come with a particularly high max bet stake. And you could find that free spins expire within just a few days. You could also need a free spin promo code to claim the offer and get the bonus spins credited to your account. With all factors considered, here is our recommended first deposit slots bonus with free spins:

100% up to £500 + 100 Free Spins
Free Spins:
100
Wagering:
35x
Eligible Slots:
4
Full T&Cs apply. New players only. 18+. Min deposit £10. Welcome package split over 3 deposits 35x wagering applies to match up bonus. Offer valid for 1 week. 100 Spins split to 20 Spins a day for 5 days - 50x wagering applies to Spins.

You should keep in mind that many free spins casino bonuses come with wagering requirements – free spins no deposit offers are a rarity. Any free spins winnings made with a free spins no deposit welcome bonus are paid as bonus money, which you need to play through a certain number of times. Free spins must be used within a specified timeframe, so make sure to use the offer before the spins expire. You could find some offers give you just a few days bonus validity for free spins.

Still, there are some free spins deposit bonuses with no wagering available at online UK casinos. With such offers, any winnings from extra spins on selected games are paid as real cash which are available for withdrawal at any time. In a similar way, the deposit balance is available to be withdrawn anytime.

Best Deposit Bonus for Slots with Low Wagering

Wagering requirements play a key role in picking the best slots deposit bonus offers to suit you. You will need to play your welcome bonus through before you can withdraw your bonus and free spins winnings. So, you should choose offers with wagering conditions that you can conveniently fulfil.

It is for this reason that many new players seek offers with low wagering. Low wagering offers could give you less cash, but it is easier to fulfil the playthrough and withdraw your winnings. In that regard, they are often better than the ever-so-popular free no deposit bonus, since freeing the bonus funds is actually easier. Here is the first deposit slot bonus with the lowest wagering for September, 2021:

Up to £400 on Classic Slots
Wagering:
20x
Slot Weight:
100%
Min Deposit:
£20
Full T&Cs apply. 100% buy-in up to £400 buy-in bonus. Min £20 cash buy-in to be eligible. Offer only available on classic slot games. Max bonus £400. Max stake £2. 20x wagering requirements on total of buy-in and bonus amount. Bonus is valid for 7 days. Keep it fun - set your deposit limit.

Let’s look at an example that underlines how low wagering casino bonuses are beneficial for new players. Let’s say you accept a £100 bonus with a low playthrough requirement of 20x. In this case, you would need to bet £2000 before your winnings can be withdrawn. In comparison, the same bonus amount with 100x wagering would require you to bet £10,000. So, the lower the wagering requirement, the easier and quicker it will be to play through the casino bonus and get your hands on your winnings.

Keep in mind that the max bet with bonus cash will also affect how conveniently you can wager the bonus. So too can the the amount of time before free spins expire. There may also be a max win applied to the bonus. Plus, not all games count towards bonus wagering. It’s worth knowing that a free spins no deposit welcome bonus will usually come with higher wagering requirements than a deposit bonus. Such offers may also require a promo code.

Online Slot Games with a Mobile Deposit Bonus

Mobile casino apps offer the most convenient way to play online slots with real money. Many UK players prefer to play mobile slots on a mobile device. As such, all reliable online casinos offer UK players the option to play on the go. Most British casino websites are mobile compatible, and you can deposit and play mobile slots directly in your mobile browser on Android and iOS devices.

Some operators also offer native apps that you can download from the respective app store. Whether you play through a web app or native app, you can easily deposit and claim a slots deposit bonus on your mobile. With that in mind, here are the best mobile deposit slot offers for UK players:
