This just might be the king of slot casinos! It features a truly bold design with a powerful black and red palette, and a superb user experience.

There is a great selection of slots available but you can also find a decent selection of live casino games on offer. Finding the game you want to play is such a breeze. You can either explore games by provider or use their intuitive search bar.

One thing I’m a big fan of is having both bonus and real money in easy view rather as one amount. This always helps me better keep track of my money. Another plus is the possibility to demo games before playing for real money.

Probably the only negative I came across was having to part with an extra £2.50 to complete my withdrawal. Unfortunately, all withdrawals (no matter the amount) are subject to this processing fee. For what it’s worth, however, the withdrawal process was lightning fast.

Overall rating:

As soon as I finalised my deposit a popup appeared letting me know the deposit was successful. Right there I could see £40 in real money and another £40 in bonus money clearly displayed.

After I clicked OK another popup advised me I had 20 spins of Book of Dead available. Without hesitation, I clicked to go to the game and take advantage of the free spins. These only resulted in 60p worth of winnings but there is nothing better than some free spins to warm you up.

Bonus money and wins from free spins need to be wagered 50 times before cashing out, which is slightly above current industry trends. Having said that, a 100% bonus such as this one, gives you enough funds to truly experience a new casino.

Apart from that, at SlotKing Casino there always seems to be some kind of ongoing promotion. The include leaderboards and opportunities for cashback.

There are plenty of games to choose from here. Live casino is powered by Evolution and you will find slots from popular providers such as NetEnt, Play’N GO and Microgaming amongst others. Unfortunately, I couldn’t see any of the progressive Microgaming games which was a little disappointing.

As it’s been a while since I was in a casino which had Microgaming slots I opted for a few rounds on ThunderStruck II. What I wanted to play was Game of Thrones (but an error was coming up in the game from the provider's side). ThunderStruck II didn’t yield any wins. In fact, during the first 20 spins, nothing happened!

Next up I tried my hand at a few live casino games. Whilst live casino is powered by Evolution I couldn’t find the usual game show games such as Deal or No Deal. So I settled for the next best thing: Lightning Roulette.

I had a few rounds on my usual numbers but these didn’t come up. So back to the lobby, I went to have a good go at Reactoonz 2. It was only after a few spins that the chemical explosions went mad and the Gargantuan made an appearance helping me win over £20 from a 25p bet.

There’s little fault with SlotKing Casino’s mobile experience. I accessed the site via the Chrome browser of an iOS device and the experience was just flawless. Searching for games is as easy as it is on desktop and the site responds amazingly well whatever game you are playing.

I started playing the Christmas version of Aloha: Cluster Pays where I managed to enter the free spins round within a few spins. This was quite a surprise as in my years playing Aloha this had always been out of reach. I was playing at 10p a spin and managed to win a nifty £11.50.

After that, I changed the game and started playing Microgaming’s Lucha Legends. This is an incredibly fun game with a comic design and festive soundtrack. Here I entered the free spins round 3 times but never managed to win anything above £2.

I quickly created my account through a 2-step process which asked for the usual details. After this, a pop-up notified me that an activation was sent to my phone and my email. I checked my email and sure enough, I had received a four-digit code together with a welcome email from SlotKing Casino.

As soon as I entered the four-digit code, my account was verified and I was ready to go ahead with my deposit.

Even when it came to withdrawing my winnings - a £50 withdrawal - I wasn’t asked to send in any documents. This is probably due to the fact I used a Visa Debit Card issued by a local bank.

Slotkingcasino accepts all the major Banking options. They accept VISA, Master and Maestro card. Paypal, Payviaphone, Instant Interac, Bitbaypay, Zimpler, Ecopayz. Methods may vary depending on player's residence.

As with other casinos by Progress Play, money transfers are impeccable. Depositing is easy and there are several ways you can fund your casino account. I deposited £40 using a Visa Debit Card. The process was swift and painless.

It was when I went to cashout that there was a little surprise waiting for me. Every withdrawal, no matter the amount is subject to a £2.50 processing fee. Having said that, I don’t mind a processing fee when withdrawals are taken care of in record time. Within less than 2 hours I had an email saying the withdrawal was successful. The money was in my account the next day!
