Bonus Accumulator Review: A Legit Way To Profit From Casino Offers?

Boost My Budget uses affiliate links.

2021 update: Bonus Accumulator has been combined with Profit Accumulator under the Diamond Membership package and no longer exists as a separate site.

If you follow my blog, you know I’m a big fan of matched betting.

I’ve experimented with a LOT of ways to earn extra cash, and I can tell you that matched betting is the single best way to make decent money fast in the UK.

I’ve long been a paid-up member of Profit Accumulator (now rebranded as for matched betting. This is the site that provides the tools, calculators and training to make your profits.

So I was intrigued to hear that the folks behind Profit Accumulator have launched a new site – Bonus Accumulator.

Bonus Accumulator focuses on how to make money with casino offers. This is pretty different from matched betting, as there is more chance involved.

But they claim it is still possible to make big money doing this – even from risk-free or low-risk offers.

I tested it out to find out how much you can make with casino offers, and whether it’s worth it.

Here’s my honest Bonus Accumulator review.

I would also like to note that I was gifted a free trial at Bonus Accumulator to test it out for the purposes of this review. This does not affect my thoughts on the service. I have since voluntarily become a paid member 🙂

How does Bonus Accumulator work?

How to make money online betting on casino offers - with low risk! This new website promises you can make over £3000 low risk with their guide to profiting from online casinos. But are they legit? I tested it out so you don't have to...

Bonus Accumulator is a site that guides you though how to profit from casino offers on betting websites.

They search out all the best casino bonus offers for you, and talk you through how to play them to maximise your profit and minimise risk.

There are sections for signup offers (when you first join a site) and reload offers (offered to existing members).

Within these sections, the offers are divided into risk free, low risk, medium risk and high risk.

Bonus Accumulator claim that the signup offers listed on their site have an initial expected value of more than £3,600, with reload offers of expected values of £650+ per month. 

When you sign up, you should start with the guides. The first two guides explain about risk and how to mitigate it. It’s very important you read and understand these before you start.

There are also guides that teach you how to play the common casino games.

Then you get onto the offers.

Bonus Accumulator lists all the different offers you can do each day, with detailed instructions such as which slot will give you the best chance of winning, and how much to bet on each spin.

They also list the EV (expected value) of each offer. This is a mathematic calculation based on the average win.

Of course, there are no guaranteed wins with casino offers, but the EV is a useful guide to which offers are most worth your time. And overall, I’ve found that my winnings have generally followed the EV.

Another interesting feature is that each offer has an estimated cost per hour. This is another good way to get an idea of which offers are worth your time.

However, I thought this was potentially a bit misleading as obviously you don’t get the option of playing the slot for an hour straight!

Bonus Accumulator also have a whole host of other features such as a profit tracker, a slots database, a simulator and blackjack calculator.

What kinds of offer can you do?

The most common type of offer are slots. Sometimes you will also have the option to play other casino games like blackjack or roulette.

The special offers that you can profit from are usually free spins or bonuses (free cash to play with).

The factors that affect whether offers are risk-free, low-risk or high-risk are whether you have to deposit your own money first, and whether there are any wagering requirements.

For example, a typical risk-free offer might give you 20 free spins on a slot game, and you can withdraw any winnings instantly. There’s literally nothing to lose!

A higher risk offer might require you to deposit and play £10 of your own money first. Then you will get a £10 bonus, but you have to wager (play through) the winnings from your bonus before you can withdraw.

In this second scenario, you could lose some or all of your initial £10 deposit. But when you factor in the £10 bonus, you are likely to make a profit overall.

Aren’t casino offers just gambling?

So here is the main difference between casino offers and matched betting:

Matched betting is NOT gambling. It’s based on maths. You use special calculators to work out exactly how much to bet, placing two opposite bets on different sites.

With matched betting, you actually know exactly how much you will make from each bet before it even settles.

On the other hand, there are no guarantees with casino offers.


EV (and the simulator in the Tools section) give you an idea, but there are no calculators that can tell you exactly how much you will make from each spin on a slot machine. 

You could get 30 free spins and come away with nothing. Or, you could hit a bonus round and win £500 on your first spin.

So yes, basically, casino offers ARE gambling (apart from the small number of no risk sign up offers).

BUT – this is where Bonus Accumulator comes in.

How does Bonus Accumulator reduce your risk?

Most casino offers are not risk-free.

But when you use Bonus Accumulator, the risk is highly reduced, compared to normal gambling.

This is because Bonus Accumulator only introduces offers with a positive EV. Then, it shows you how to exploit the offers to make the most of bonus cash, and minimise the risk to your own cash.

Rather than just randomly depositing money and spinning away on the slots, you’ll only be taking part in offers where you are highly likely to make a profit.

Usually the bookies have the edge, because obviously the games are set up to make them money. But if you make use of bonuses and special offers as BA shows you, you will have the edge, because you are not gambling (so much of) your own cash. 

Basically, they teach you which offers are worth taking a small gamble on – and how to maximise your chances by choosing the most efficient slots and so on.

One very important thing to keep in mind is that casino offers are all about the volume of offers you complete. Most games you will just win a small amount, or perhaps lose a little.

BUT, if you play enough, eventually you’ll to hit a big win of several hundred pounds or even more. Over time, this all averages out and you should see that you are making a decent return overall – even if you also see some losses along the way.

Risk free offers

There are also some no-risk offers on the site. These are clearly marked in their own section, and they’re the first offers you’ll do after signing up. 

At the time of writing, the Expected Value of the no-risk offers is over £50. So you could just do those, then quit before any actual gambling.

There’s also several £100s worth of sign up offers in the low risk section.

With low-risk offers, you may make a small loss on some of them, but the law of averages says you will still come out ahead overall.

How much can you make on Bonus Accumulator?

So Bonus Accumulator claim that that the expected value (EV) of their sign up offers is more than £3,600. The reload offers have an EV of over £650 per month. 

Those are impressive numbers, and who wouldn’t be tempted by an extra £3,600?!

However, there are a couple of things to keep in mind here:

Firstly, this figure includes all the offers on the site – including the high-risk section.

The high-risk section is not for everyone. It should be approached with caution. And you need a very large bankroll (several £1000s!!) to take on most of these offers.

I’m staying clear of high-risk myself, because I don’t have the stomach or the bankroll for the potential losses.

Secondly, you will only be able to do all of these sign up offers if you don’t already hold accounts with any of the bookies. If you do matched betting, or you gamble a bit anyway, you won’t be eligible for many of the offers.

Still, there are several hundred pounds worth of offers in the no-risk and low-risk sections. And there are so many different offers, that even if you’ve done a lot of matched betting, you are sure to find lots of new sites to join.

Another important thing to mention is that all your earnings through Bonus Acca are TAX FREE!

This is because casino and betting winnings are not counted as ‘trading income’ and therefore not taxable in the UK (source). 

You don’t have to register as self-employed or declare any earnings from casino offers or matched betting – making this an ideal side hustle for anyone who wants to earn some extra cash without the paperwork.

Let’s take a look at how I got on.

My results

a screenshot showing my earnings after 10 days of casino offers on bonus accumulator

I took this screenshot after I’d been a member for 9 days. I aimed to do one hour of Bonus Accumulator per day. As you can see, I made almost £100 in 9 days!

I made on average just over £10 per hour. Not huge riches, but much more than you can make doing surveys.

This was just doing the risk-free and a few low-risk offers. And since I’ve done a lot of matched betting, over half the offers were not available to me.

I was actually surprised how steady and reliable the income was. Here’s the graph from Bonus Acca that shows how closely my profits followed the EV:

However, I’ve been told that the earning get less consistent as you get on to the higher risk offers. The higher the risk, the more likely you are to see big wins and big losses.

Bonus Accumulator features and support

Bonus Accumulator has some pretty cool features that are worth mentioning.

Blackjack calculator

Bonus Acca often recommends using Blackjack for wagering where possible, because it has a high RTP (return to player). They have a calculator you can use to tell you what move to make.

I did already know the basics of blackjack, but I definitely did better using this calculator than I would have done on my own.

Slots database

Not all slots are created equal! And not all sites have the same range of slots, which means even if you find a favourite, you might not always get to use it.

Bonus Accumulator has a slot database to help you identify the most profitable slot games.

Profit tracker

You can log all the offers completed, your profits and loss directly in Bonus Accumulator.

They have a couple of different ways of viewing the data and tracking your progress. I found this really useful and I like the visual way of tracking profit against EV.

Customer support

Customer support is available 5 days a week to talk you through any offers or issues. You can contact them by email, Facebook messenger or Twitter. 

Outside of office hours, you can also use one of the following methods for support:

Facebook group

There are currently 2.4k members in the Facebook group and it’s extremely active. It’s a great place to post for advice on the offers. There is always a BA staff member ready to hop in, but you will also get help from other members.

The group is also a great source of inspiration as lots of members share screenshots of their big wins!


There is a forum on the BA platform with dedicated threads for each offer, as well as general chat.

The forum doesn’t seem to be that active yet (probably because the Facebook group is easier to use) but it’s monitored by staff and a good extra source of assistance if you need it.

Bonus Accumulator prices

Like Profit Accumulator, Bonus Accumulator has two pricing tiers: monthly at £17.99/month, or annual at £150/year (the equivalent of £12.50/month). 

Both offer the exact same benefits and features, it just depends how you’d rather pay. 

Personally I’ve gone for the monthly option for now, because I’d like to see how much I can make consistently from reloads after I’ve finished the sign up offers before making a long-term commitment.

This is a completely separate platform from Profit Accumulator and there is no discount for members of both.

I did find that a bit disappointing, and I don’t know if I will continue as a member of both in the long run. I would love to see them add some kind of joint membership bundle in future.

Another disappointing thing is that there is no free or reduced trial (unlike Profit Accumulator where you can earn around £40 from the free trial with no strings attached). You don’t get to peek inside the platform without paying a monthly fee.

However, even though the Bonus Accumulator pricing might seem quite expensive at first glance, I made enough to cover the monthly fee within about 90 minutes.

As I mentioned above, there is over £50 worth of offers in the no-risk section alone, and several £100s in the low-risk section. So you are bound to make your £17 back pretty swiftly.

Who should join Bonus Accumulator?

Bonus Accumulator is for you if:

  • You’re over 18
  • You live in the UK or Ireland
  • You want to make extra money online fast, in a relatively low-effort way (as opposed to, say, starting an online business)
  • You have £10 to £100 to start with (you don’t need much to start, but the more cash you can spare upfront, the quicker you can get through the signup offers)
  • You already do matched betting and you want to increase your earnings with casino offers (especially useful during coronavirus or the sports off seasons)
  • Or, you’re interested in matched betting, but baffled by all the sports terminology (note, you don’t actually need to know anything about sports to do matched betting – but I would say casino offers are easier to start with)
  • It would also make a great alternative to matched betting if you’ve lost a lot of accounts (gubbing from the sportbook usually doesn’t affect your promotions on casino sites, even if they’re a different section of the same bookie)
  • You recognise that casino offers are NOT completely risk free, but you ARE almost certain to make a good profit if you just keep working through the offers and following the instructions
  • You know when to stop.

…and who should NOT join!

Bonus Accumulator membership is not available to anyone under 18, or who lives outside of the UK or Ireland.

Please don’t think you can get around these rules by using fake details on the casino sites. Many of them will ask to see ID before releasing your funds.

They actually have a legal requirement to verify your identity for anti-money laundering regulations and so on.

One thing I really want to stress is that you should NOT do casino offers if you have any history of gambling problems, or if you have an addictive personality.

I always say this about matched betting anyway, but I think it’s even more important with casino offers.

By their very nature, casino games are designed to be addictive. They’re more fun than sports betting (for me, anyway!) and it’s so easy to think ‘just one more spin…’.

You need to have iron self-control and just follow the offers as listed on Bonus Acca, or you could slip into real gambling.

One last point: if you are planning to apply for a mortgage in the next few months, I would hold off on casino offers and matched betting for now. Some mortgage providers want to see your bank statements, and a lot of bookie transactions could raise red flags.

This isn’t always an issue, but in my opinion it’s not worth the risk.

Bonus Accumulator vs Profit Accumulator: is it worth joining if I’ve already done the casino offers on Profit Accumulator?

Profit Accumulator does have a pretty good casino section, so you may be wondering if it’s worth joining both.

Well, if you are serious about casino offers, then you will want to join Bonus Acca.

I’ve done a lot of matched betting myself, so I was already a member of most of the main betting sites, and a lot of casino sites too.

However, I still found enough new offers on BA to make nearly £100 in 9 days – with plenty of signups left to complete.

I went through both sites again for this review and I can confirm that Bonus Acca have a LOT more offers.

At the time of writing, there are 196 casino signup offers on Bonus Accumulator, compared to 69 casino signup offers on Profit Accumulator.

Also, there are 69 casino reload offers on Bonus Accumulator, compared to just 35 casino reload offers on Profit Accumulator. (The number of reloads will change daily.)

And of course, you also get more specialised support and features for casino offers exclusively on Bonus Accumulator, such as the slots database, simulator and the EV tracker.

Tips for making the most of Bonus Accumulator

If you’re ready to dive in and start making money on casino offers, here are my top tips to maximise your time on Bonus Accumulator:

  • Use a separate bank account for your casino offers. You can quickly and easily open an app-based bank account with Starling or Monzo. This separates your casino money from your everyday funds and stops you going over your designated bankroll. It also makes it easier to track.
  • Use a separate email address. The sites will send you LOTS of promotional emails, which is annoying in your main inbox, but you don’t want to opt out because you’ll get loads of good bonuses that way!
  • Always use your real personal details – this is a legal requirement and the sites may check ID before withdrawing.
  • Follow all the instructions on Bonus Acca word for word!
  • If you get sent any special offers by email and you can’t find them on the website, check in the Facebook group or with support to see if it’s worth your time.

Bonus Accumulator review conclusion: do I recommend it?

2021 update: Bonus Accumulator has been combined with Profit Accumulator under the Diamond Membership package and no longer exists as a separate site.

After testing out Bonus Accumulator myself for 10 days, YES I do recommend it! 

Personally I was pretty wary of casino offers. Unlike matched betting, there are no guaranteed profits.

However, I was pleasantly surprised with my earnings throughout my 10 day trial. I was especially impressed how closely my winnings followed the EV. This helped me gain a lot of trust in the system.

Bonus Accumulator gave me a free trial for the purposes of this review, but once that finished I chose to purchase a paid membership on the rolling monthly plan.

I do feel like the service is good value for money and I’m confident I will get a good return on the monthly fee – at least in the first couple of months as I work through the signup offers.

The reason I went for the monthly subscription rather than yearly is that I haven’t yet tested out the reload offers, and I’m not sure they will be quite as profitable (since I plan to steer clear of the higher risk offers).

And I’m not sure I will stay a member of both BA and PA in the long run, since I don’t have time to do both justice.

If you’re interested in giving Bonus Accumulator a go, you can sign up here.
