The SlotSite bonus for new players includes up to £150 in bonus cash and 150 free spins. But it’s not the only welcome offer available; if you prefer the casino’s bingo games, you can claim £20 in bingo bonuses instead.
Don’t worry, I’ll cover everything you need to know about both of these welcome offers, so you know how to make the right decision for you. If you keep reading this review, you’ll also learn more about the ongoing promotions offered by SlotSite, alongside its rewards program and plenty more exciting opportunities.

SlotSite welcome package: Up to £150 and 150 free spins

As a new player joining SlotSite for the first time using any of my links, you can claim up to £150 in bonus cash and 150 free spins. Despite there being two welcome offers, it’s clear this is the more popular option, as it aligns with more traditional casino games. It gives you a better opportunity to explore the huge selection of casino games I noted in my recent SlotSite review. Plus, the rewards are typically larger, although it is important to mention that to claim the full bonus, you’ll need to make a series of four deposits.

How to claim the welcome bonus

To claim this bonus, you’ll need to start by creating an account and ID-verifying it using any of my links on this page. Once complete, you will need to deposit at least £10 at the casino cashier with any of the accepted payment methods, excluding Neteller and Skrill. The following bonuses will be applied to each of your first four deposits:

DepositDeposit matchFree spins
1st deposit100% match up to £5030 free spins (Big Bass Vegas Double Down Deluxe)
2nd deposit50% match up to £5030 free spins (Book of Dead)
3rd deposit25% match up to £5030 free spins (Big Bass Bonanza)
4th depositN/a60 free spins (Gates Of Olympus)

How to use the bonus cash from this deposit bonus

The bonus cash you receive from this SlotSite welcome bonus must be wagered at least 10 times within 30 days of the bonus being credited to your account. Failure to meet the wagering requirement before the end of the validity window will result in any unwagered bonus cash being forfeited.

Additionally, while the bonus cash can be used on a majority of casino games, contributions may vary by game. You can find a full list of wagering contributions in the terms and conditions. Finally, the maximum conversion amount for bonus cash is one times the original bonus amount.

How to use the SlotSite free spins from this promo

Any winnings from free spins in this SlotSite promotion must be wagered at least 10 times. However, you’ll only have 7 days to meet the wagering requirement, meaning it makes sense to prioritise wagering of free spins over bonus cash. Keep in mind that the same rules apply to game wagering contributions when using your free spins winnings. There’s also a maximum conversion amount of £20.

Alternative welcome offer: Deposit £10 and get £20 for bingo

You can only choose one SlotSite welcome offer, but there is a generous alternative for bingo fans. When you deposit £10 or more at the bingo cashier, after registering with any of my links, you’ll receive £20 in bonus cash to use on bingo games. Skrill and Neteller are still among the excluded deposit methods, but if you’ve met the deposit requirements, the bonus should be applied instantly. It can be used to play games such as:

  • 90 Ball
  • 80 Ball
  • 75 Ball
  • Deal or No Deal
  • Speed Bingo

However, when playing these eligible bingo games, a 2x wagering requirement is applicable, and must be fulfilled within 30 days. While this may seem slightly more appealing than the previous casino welcome offer, the rewards are also much smaller. Additionally, the bingo welcome offer has a maximum conversion amount of £60, or three times the original bonus amount.

Spin the weekly bonus wheels at SlotSite

Throughout the week, you’ll have the chance to participate in two SlotSite existing player bonuses offering up to 500 free spins. Here’s a quick look at how each works:

Midweek Wheel of Spins

Every Wednesday, you can deposit £20 or more at SlotSite to claim up to 500 free spins. However, the number of free spins you actually receive is random and decided by where the Wheel of Spins lands. Here’s a breakdown of the potential rewards and your likelihood of receiving them:

PrizePercentage of winning
5 free spins1%
10 free spins5%
15 free spins18%
20 free spins22%
30 free spins25%
45 free spins18%
80 free spins5%
100 free spins3%
300 free spins2%
500 free spins1%

You must use your Wheel of Spins within 24 hours of making your qualifying deposit. Then, any winnings you receive from free spins credited to your account must be wagered 10 times within 7 days. A maximum conversion amount of £20 is also applicable, and deposits via Skrill or Neteller are excluded.

Weekend Wheel Of Spins

If you missed out on the Midweek Wheel of Spins, you can participate in the Weekend Wheel of Spins instead. This bonus is active from Friday at 00:00 GMT till Sunday at 23:59 GMT, and the terms mirror those of the Midweek promotion.

You’ll need to deposit at least £20 to spin the wheel, where you can win up to 500 free spins. The odds of landing each prize are exactly the same, so you can refer to the previous table for a breakdown. Additionally, the wagering requirements, expiry times, and maximum conversion limits also remain unchanged.

How does the SlotSite rewards program work?

I’m a big fan of the rewards program at SlotSite, as it has a simple setup, making it easy for beginners to understand. Essentially, you’ll collect rewards points through any of the following:

  • Gameplay – The more time you spend playing casino games at SlotSite, the more points you collect.
  • Missions – Complete specific tasks, such as playing specific games, triggering slot features, and claiming bonuses.

Your points will be linked to your status within the program, helping you unlock new levels and achievement badges. As your status increases, you’ll unlock exclusive deals, first access to new games, special tournaments, and more. Additionally, your points can be used in the rewards store to unlock free spins, deposit bonuses, and cashback rewards.

Claim a mystery box once every week at SlotSite

Another SlotSite reload bonus you can claim throughout the week is known as the Mystery Box promotion. To qualify, you must log in on any day between Monday at 00:00 GMT and Thursday at 23:59 GMT, and make a qualifying deposit of at least £20. This will get you 1 Mystery Box minigame play, which can award any of the following prizes:

PrizePercentage of winning
25 free spins36.5%
35 free spins36.5%
45 free spins10.43%
55 free spins10.43%
65 free spins5.21%
100 free spins0.94%

Keep in mind that this bonus is available once per day, so you could potentially claim up to 400 free spins a week with this promotion. The bonus terms are also pretty reasonable. Your Mystery Box minigame must be used within 24 hours of receiving it. Any free spins and their winnings you receive must be wagered 10x within 7 days, and there is a maximum conversion amount of £20.

Which payment methods are accepted for SlotSite deposit bonuses?

After reading the terms for various SlotSite deposit bonuses, I noticed that Skrill and Neteller were frequently excluded. However, the site supports a wide range of instant deposit methods, including:

✅ Visa

✅ Mastercard

✅ PayPal

✅ PayviaPhone

✅ Apple Pay

✅ Pay by Bank

✅ PaySafeCard

✅ Payz

✅ NeoSurf

Despite the variety of options, it’s always a smart move to review the bonus terms yourself before making a deposit. This helps to ensure you aren’t accidentally caught out and unintentionally disqualified from a promotion. You can also take the time to review other key terms, including the minimum deposit amount, which can vary.

What casino games can you use your SlotSite bonus on?

Importantly, you’ll need to review the terms of your SlotSite deposit bonus to see wagering contributions for different games. However, you can find a wide range of genres available at this online casino, including:

  • Slot games, including jackpots, megaways, hold & win, classics, cascading reels, and more.
  • Virtual tables, including blackjack, roulette, baccarat, and solitaire.
  • Casual games, including keno, lotto, scratch cards, and more.
  • Live casino games, including roulette, blackjack, baccarat, and game shows.
  • Bingo games, including 90-ball, 80-ball, 75-ball, Deal or No Deal, and speed bingo.

Look out for the game of the week

In the SlotSite promotions tab, you’ll find a new Game of the Week added regularly. It usually spotlights one of the casino’s most popular and best-performing titles, so if you’re unsure where to start, this could be a strong option.

Are SlotSite promotions actually worth claiming?

I’m a huge fan of SlotSite promotions, and it’s an online casino I would highly recommend to UK players. While the casino welcome bonus felt like the obvious choice for me, I appreciated the flexibility provided by the bingo welcome offer. Both of these welcome bonuses offer significant value and have relaxed bonus terms, making them easy to use. SlotSite also features an impressive selection of ongoing promotions, including weekly reloads, rewards programs, and more.
