Kaiser Slots Casino aims to rule your casino experience with an iron fist. Instead of just being a despot, the site is brimming with hundreds of top-notch casino games from leading software developers, including the likes of NetEnt and Microgaming.

Kaiser Slots, as the name suggests, is king for the online slot enthusiast. With over 1,000 games, you will find just about any slot you want to play. 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.

Since launching in 2017, Kaiser Slots Casino has been turning heads for all the right reasons. Navigating around the site is a delight and the graphics have been embellished to help make your online gambling experience, a pleasant one. The casino operates on the Aspire platform, which is a blessing and a curse. Visually, the site doesn't really stand out, but the base is still good.

With an nice welcome bonus, excellent mobile site and whole heap of slots, I decided I must check Kaiser Slots out.

No need to worry about safety and security here, as this online casino is licensed and regulated by both the UK Gambling Commission and the Malta Gaming Authority.

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!

Kaiser Slots first deposit bonus

The Kaiser is making rounds and handing out bonuses for all players. Make a deposit and you can get the following bonus.

New Players Only 18+ (UK only). Min deposit: £10. Maximum Offer: 250% Bonus up to £35 & 20 Spins on Starburst. Bonus & Spins winnings must be wagered 35x before withdrawal. Spins expire after 24hrs.

Join Kaiser Slots Casino today and start reaping the benefits of being a player. Their welcome bonus has a kick to it, even though it's not a massive one.

Sign up and start making deposits to receive the following offer:

  • 250% bonus up to £35 + 20 spins

Follow the below simple steps to get started:

  1. Sign up for a Kaiser Slots Casino account
  2. Verify your account by email
  3. Make a minimum deposit of £10
  4. Your welcome bonus will be credited to your account

I found Kaiser's welcome bonus to be a nice 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.

As this is a first deposit bonus, you will need to make a minimum deposit of £10 to be eligible to play. That is actually pretty nice low requirement, and the 35x wagering requirement fits the industry standards.

Looking at the other limitations, there is only the standard maximum bet limit, which is £4 here, so not a bad one.

And that's about it. There was no real twists or surprises here, just your average terms. What this is, is a spicy bonus that gives you a nice start. It's not a big one, but you only need to deposit a very small amount to get it.

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.

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 1,000 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.

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 900 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.

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.

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.

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.

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. 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.

Kaiser Slots Casino's customer support team is available at your beck and call, every day between 6 a.m. and 11 p.m.:

  • Email support: ✅
  • Live support:
  • Phone support: ❌

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. 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.

Keep the following documents at hand when starting you journey at Kaiser Slots:

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

For most players, gambling is a fun pastime. Unfortunately, for a small group of players, gambling can spiral out of control.

To stay in control over your gambling, you can avail yourself of the below tools:

  • Deposit Limits
  • Reality Checks
  • Time Out
  • Self-Exclusion

If you require further assistance, you can either phone GamCare on 0808 8020 133 or else, install filtering software such as Net Nanny and CYBERsitter.
