Kaiser Slots, as the name suggests, is king for the online slot enthusiast. With over 900 games, you will find just about any slot you want to play. And with more than 700 of these slot machines available on mobile, Kaiser Slots is also the undisputed king (or queen, depending on who’s playing) of slots on the road, allowing you to spin the reels from anywhere, at any time.

With an eye-catching welcome bonus, excellent mobile site and more slots than I can play in a lifetime (ok, considering I’m old), I decided I must check Kaiser Slots out.

As it is a dedicated slot portal, you won’t find on Kaiser Slots any casino table games, making this site a singular gambling experience. Is Kaiser Slots an impressive speciality site? Or a one-trick pony? Join me for a spin of the reels of Kaiser Slots, and let’s find out!

Many online casinos make a big effort to appeal to new players with their welcome bonus. Some of these deals stand out more than others by providing a lucrative welcome package that is hard to resist. On paper, I found Kaiser’s welcome bonus to a great one. Of course, there is more to any casino bonus than the flashy sales pitch. With that in mind, I decided to scratch below the surface to see if the blockbuster newcomer deal at Kaiser Slots stacks up. Let’s start with the upfront information - this bonus can deliver a 100% deposit match up to £100, and Kaiser will also throw in 100 free spins on top.

As this is a first deposit match bonus, you will need to make a minimum deposit of £10 to be eligible to play. That is all fine, but the wagering requirements may trip some players up because it is 35x the bonus sum, tipping towards the higher end of the scale.

So, you probably want to know if this is a good welcome package? The answer is yes because this is an excellent bonus for newcomers. You get a very generous deposit match bonus with an achievable wagering requirement and free spins on one of the best online slots ever made. As an additional perk, Kaiser Slots also lets players withdraw deposits before the wagering requirements are fulfilled, although this will void the remainder of the bonus.

Slots by name and slots by nature - that is the story of the game selection available at Kaiser Slots. This site focuses on slot games while offering a small selection of other types of games. When you visit Kaiser, it is for the vast selection of slot titles from leading online casino software developers like Microgaming, NetEnt, Play’n Go, and more.

In terms of letting you find games easily, Kaiser Slots does an excellent job. I am not the biggest fan of the overall website design because it lacks some of the style of other casino sites. Still, the user interface for the games list and the ability to find titles is top-notch. Firstly, Kaiser Slots displays all its available games in a grid section.

When there are over 900 slots available on the site, that initial grid can be overwhelming. But you can narrow down your search by separating games by category. Kaiser offers a user-friendly system where you can organise titles by new and classic and other standard filters.

If you have a specific game in mind, you can use the intuitive search function to pinpoint the exact title. I did just that because I wanted to play Starburst, firstly because I love NetEnt’s visual masterpiece and because it is part of the free spins welcome bonus. Games load in a new page (on the same browser tab) against a dark background, and they just look fantastic when playing on Kaiser slots.

I then went on to explore something less common and took a few spins on Book of Adventure, Super Stake Edition. Stake Logic Productions make this Egyptian-themed ‘book of’ slot. It doesn’t break new grounds in terms of design, but the Super Stake side bet adds a random bonus feature that earned me some handsome wins.

Happy with my new-earned cash, I went fishing on the reels of Pragmatic Play’s Sea Bass Bonanza and Blue Print Gaming’s Fishin’ Frenzy. Sadly I lost most of my money at sea but still managed to earn some back with two exciting game editions of Fishin’ Frenzy: The Big Catch and Megaways. Of course, fishing expeditions are not the only slot types you’ll find on Kaiser Slots. From new to old, classic to cult, blockbuster to traditional - if there’s a type of online slot you can imagine, you’ll probably find it on Kaiser Slot’s website.

The game portfolio also includes around half a dozen scratch cards under their own section if you like instant win games.

There is a good chance you are visiting Kaiser Slots from your mobile device. If that’s the case, you’ll find a robust HTML5 site that is responsive and optimised for mobile devices.

Kaiser Slots doesn’t offer a native app, but its mobile website worked seamlessly on both my iPad and Android phone. The design transcends beautifully to mobile, and the stacked menus make it easy to navigate across hundreds of games. Speaking of games, over 700 slots are available on the Kaiser Slots mobile site, so what’s not to love?

Well, one downside is the limited number of mobile payment methods on the Kaiser mobile casino. However, this is a general problem for the online casino market as a whole. So I hope that it will soon add pay by phone solutions such as Apple Pay and Google Pay.

Kaiser Slots does a great job at ensuring customers are safe and having a good time, thanks to a robust customer support network. Firstly, the site has one of the best FAQ sections I have ever seen at an online casino. It provides an extensive list of answers to problems and questions at an online casino. Furthermore, the built-in search function allows you to search for an issue you have.

In terms of direct contact, Kaiser Slots provides a standard output. There is no phone number, but you do get email contact and live chat running from 08:00 to 00:00 CET 7 days a week. In all my interactions with the support team, I found them to be helpful and friendly. Email replies came within a day, which is OK but not as fast as other casino’s I’ve tested. So your best chance to get issues resolved quickly is by contacting the live chat team.

As a licensed UK casino operator, Kaiser Slots is obliged by law to run all essential security and age verification checks.

If they are unable to verify your details automatically, you’ll be requested to provide the below relevant documentation:

  • Proof of ID (passport, driving license, ID card)
  • Proof of address (utility bill, bank statement, official government letter)
  • Proof of Payment Method

Expert's review Ziv Chen

Casino tested

Signing up with Kaiser Slots took a few minutes. I just followed the instructions on screen and everything went quickly and smoothly. I was registered and logged in, and received a nice and detailed welcome email.

The verification process was also straightforward and took little time. I followed the steps of uploading the standard documents as required: a copy of my passport (it can also be a driver’s license or any other government photo ID), proof of address (I sent a copy of my utility bill) and a picture of my debit card to validate the payment method. I uploaded all the documents in a dedicated area in the site that gives detailed explanations about the process, and received an email the next day that my account was verified, so no problems there.

Being an experienced gambler, I know that I need to verify my account before being able to cash out from the casino. However, newer players that are not familiar with this UKGC requirement may be surprised when trying to initiate their first withdrawal. This could have been easily prevented if Kaiser Slots would have mentioned the verification process on the welcome email I received, or added a popup message about it upon first login as some UK casinos do. Still, in the FAQs section there is a big part about the verification process that explains everything.

You can make deposits and request withdrawals by using one of many available payment methods:

  • Debit Cards
  • EWallets
  • Prepaid Vouchers

Banking on Kaiser Slots is pretty standard compared to other UK casinos. There is a standard selection of payment methods, including e-wallets and the prepaid Paysafecard option. But it’s nothing more than average. I would have liked to see more methods, especially mobile payment options like Pay By Phone or Apple Pay.

Although it was easy enough to deposit, the welcome bonus wasn’t credited to my account automatically. So I had to contact customer support via chat. The agent was attentive and helpful, but the welcome bonus was only credited to my account after an hour or so, without me receiving any email or notification about it.

Because there are no separate balances displayed for bonus and real money (a useful feature I found in many other UK online casinos), I was confused and couldn’t keep track of my real-money spend.

The issue with the bonus balance came back to haunt me when I tried to cash out without realising that part of my withdrawal contained bonus funds that still needed to surpass wagering requirements. For me, the entire saga was no more than frustrating. But when looking at the broader sense of responsible gambling, I believe Kaiser Slots must do more to avoid these confusions and help players manage their bankrolls safely.

It was simple enough to find the withdrawal section and I initiated a withdrawal request and received money into my account within three business days. It wasn’t the quickest cashout I’ve done, but still within reasonable limits. For faster withdrawals, use e-wallets which take up to two days.
