Despite covering all the basics of an online casino, the verification delays here made this one annoying to play at.

It was pretty simple to sign up for a new account using the basic 3-step form. There was an option for using Paypal for instant signup here, but I decided to skip that and fill out all my personal details instead. The first page was for my email address and mobile number, the second page for my full address and on the final page, I created a username and password. I hit ‘Create Account’, and it took a few seconds before I got a message to say that my details couldn't be verified. I clicked on ‘Join Now’, entered all my details again, and this time my registration went through just fine.

I landed on the welcome bonus offer page where there was a basic form for me to enter my card details and make my first deposit. I did this and claimed the welcome bonus before starting to explore the site in more detail.

Taking a look around, I could see that this is a pretty stripped back casino with no extra fluff at all. I wouldn’t really say that this site has a ‘theme’ as such, but I did appreciate the simple design and colour scheme when compared to the many garish casinos around. That said, in places, it feels like there’s not enough info and options, in the account settings area for example, which doesn't even contain any active bonus stats.

Right after signing up, I got a basic form inviting me to enter my card details and claim the welcome offer of 1 spin of the Mega Reel. I dropped in £50, and once the deposit was confirmed, the Mega Reel appeared on the screen. I gave it a spin, and it landed on ‘50 Free Spins on Starburst’. I clicked ‘Play Now’, and the game started to load, but then the screen went back to the main casino lobby. I selected Starburst from the menu and when it loaded a pop-up message confirmed that I had 50 free spins to play with. I auto-played all the spins and came away with £14.43, which was instantly added to my bonus balance.

Looking at the terms of the bonus, I could see that this was another monster 65x (B) wagering offer. There wasn’t any way that I was going to play through £938 of funds to release that tiny bonus, so I decided to forfeit it on this occasion. I’m not a big fan of these randomly awarded welcome bonuses; it would be much nicer to see a solid bonus cash offer here. Also, there isn’t actually anywhere on the site that I could view my bonus wagering progress. I’d have to contact the support team every time I wanted to check on this which isn’t very transparent at all.

I kicked off the testing of the games with a few £0.30 spins on Immortal Romance, and it wasn’t long before I landed a lovely little £8 win there. Next up I tried Beat the Bobbies Jackpot and did manage to trigger the free spins game but only won a measly £2.05 there. I moved on to Irish Pot Luck where I landed a £9 win and a £6.90 win in quick succession to come away happy.

There were slim pickings under the ‘Table’ tab, but I had a few bets on Live Speed Roulette and came away a few pounds up thanks to my winning streak on red. I had a hunt around for any other live games to sample, but all the others had a minimum £10 bet which was a bit above my budget here.

I can’t say that it was the smoothest gaming experience I’ve ever had, nearly all the games had a slight lag and jerkiness to them. I checked my connection speed, and it remained stable throughout, but the casino seemed to struggle at times. That said, the basic layout of the games lobby and navigation worked just fine, and I was able to find everything I wanted to play. The only area where things are lacking is the overall games selection. The absence of big titles like Book of Dead was really felt at times.

Switching over to the mobile site, I loaded it up using the Chrome browser on my Android device and logged in. The navigation was pretty similar to the desktop site, but I’m not a big fan of the mobile site design here. While everything has its place and worked fine, the bottom menu is totally unnecessary. It has links to the cashier and trophy sections alongside Fluffy Favourites and Starburst, not two games I’d be desperate to play anytime it has to be said.

I had a session of £0.40 spins on Rainbow Jackpots where I managed to trigger the free spins round to land £18.84. Next, I tried the truly terrible slot, Prize of Paris, where I triggered the bonus feature and won £4.80 from my first few £0.20, which was quite a result. Finally, I had a few spins on Book of Gold: Double Chance where I triggered the free spins round twice and won £16.32 from just a handful of £0.40 spins.

The games I tried worked without any hitches or glitches, it was actually a better experience than the desktop site for some reason. It’s just a shame about the odd layout and design of the mobile experience here.

Searching around the site for any way to contact the support team, I only found a very basic ‘Contact Us’ page. This only had an email address on offer; otherwise, it was back to the FAQ page to find some answers which was not very reassuring. I decided to fire off an email to the address given to see how they would handle a question about withdrawals. I got an automated response back asking me to reply with my date of birth, postcode and username. I had already added these details in my original message and never actually received a reply, so it just proves how flawed this support system is.

Scanning through the FAQ page, I could see that all the basics were covered, but it really lacked any detail at all. It’s not really up to the job considering that there’s no additional info in any of the sections in the ‘My Account’ area. This page needs some serious work to make it a better resource for players and help to reduce the number of unnecessary emails the casino must be getting right now.

When I went to make my first withdrawal, I got a pop-up message informing me that my account was currently being checked over. It mentioned that this could take up to 48 hours and that I didn’t need to do anything at this stage as it was standard practice. I can’t say exactly how long it took to clear this check as I got no email to say that it had been completed. All I know is, next time I logged in, I was able to make a withdrawal request.

I had a look around the site for any information on verifying my account, but all I could find was one mention on the FAQ page under ‘Withdrawals’. This simply mentioned the type of documents that would be required and an email address to send them to. It did say that these documents can be sent in immediately after registration, but I decided to pass on this for now.

When I made my withdrawal request, I hit another snag as the casino now wanted documents to fully verify my account. I sent in an image of my driving licence and bank statement as proof of ID and address respectively. It took just over 22 hours for the verification to complete and I got an email to confirm that my account had now been fully verified. This was a pretty quick turn around but given the annoying additional delay in making a withdrawal request and lack of upload portal I can’t offer a higher rating here.

You can easily fund your Avenger Slots casino account via one of the below methods:

  • Debit Cards
  • EWallets
  • Prepaid Vouchers

Avenger Slots supports also PayPal Quick Registration, which lets you create an account and deposit with using just your PayPal logins.

Once you have verified your account, your withdrawal request will be pending for circa 72 hours. Your funds will reach your banking account within 3 days, depending on your preferred payment of choice.

Just after signing up, a simple form appeared where I could enter my name and card details to drop in my first deposit and claim the welcome offer. I filled in the form and hit the big green ‘Deposit Now’ button, and less than 5 seconds later the banking app on my phone confirmed the funds had been taken. On the screen, the balance was still showing £0, but a quick refresh of the browser rectified this, and the Mega Reel appeared on the screen.

Coming to make a withdrawal, I hit a snag right away. When I clicked on the ‘Withdrawal’ tab in the cashier section, I saw a pop-up message that said my account was currently being checked. It said this would take around 48 hours and meant that I couldn't put in a request for my funds until the checks had been completed.

Once the checks were completed, I navigated over to the cashier section, which contained a lot of small print, never a sight that sets my mind at ease. In amongst the text, there was mention of the £2.50 levied on all withdrawals here, regardless of their size. There was also a mention of my remaining wagering and current bonus balance which I was going to forfeit.

I entered my real cash balance amount and hit ‘Withdraw’. I got a pop-up confirming that I was about to lose my bonus balance and clicked on ‘Carry On’ to proceed. The final pop-up notification laid out the fees and cash-out balance and said that it would take between 1 and 3 working days for my request to be approved. I hit ‘Confirm’, re-entered my password and finally saw a confirmation screen. This stated that I’d need to send in some documentation before my request could be approved.

Once my account was fully verified, it took just under 23 hours for my withdrawal to be approved by Avenger Slots. This is a fairly quick turn around for a first withdrawal request but expected given all the verification delays. That said, the cashier function here was easy to use but it’s just a shame about that £2.50 fee.
