What Winissimo Casino has in store for you with regards to slot games?

We offer all the slot lovers with an extensive collection of top-class slot games that can be accessed on multiple platforms with just a click of a button. The players can simply carry the casino in their pocket now (it’s not a big deal for us), but the question here is, what exactly can you look forward to when it comes to playing online slots at Winissimo. Well, below are the various types of UK online slots you’ll get to try at Winissimo. Take a close look!

3-reel slots

Remember the original slot machines decades ago that started it all? Well, we’ve still got those for you. These slot games have simple layouts and are easy to play. Just match the symbols along the top, middle, or bottom row to win.

5-reel slots

5-reel slots are fun, but players want more. So, Winissimo added a couple more reels and many more features. More reels mean more payline possibilities and the chance to win more cash prizes

Progressive slots

When all the slot machines in a casino were electronically connected to raise a single prize every time a player spun on any of the machines, Progressive slots were born. Our progressive slots aren’t connected electronically, but they are tens of times more fun and offer much bigger prizes.

Mega spin slots

If you’re a slot machine freak just like us, then we understand that sometimes, playing on a single slot machine at a time just doesn’t cut it. This is why our Mega spin slots will allow you to bet on four, five, six, or even more online slots at a time. Some of our new online slots in the UK even have progressive jackpot features so that when you win, you win big.

Mobile slots

Our slot games won’t leave your side even on the move. If you wish to spin on the move, we have mobile slots that are designed specifically for mobile devices. Winissimo’s customised user interface ensures that you don’t get the short end just because you’re on a smaller device.

Themed slots

Are you a fan of popular culture? Who isn’t? That’s why Winissimo has added a huge list of themed slots so you can spin with your favourite movie, cartoon, or TV show character. Our most popular themed slots are Lara Croft, Conan, and Dead or Alive 2. Check them out today! Hurry!

Apart from online slot games, you can also engross yourself in playing other classic casino table games such as Roulette, Blackjack and Baccarat. These are sure to captivate your senses thus offering you lots of fun and instant thrill. 

Furthermore, we also pride ourselves in offering an exceptional live casino experience by featuring highly-engaging live table games accompanied by super-proficient live dealers who assist and monitor the players throughout the gameplay. 

Our uniqueness

Slots are a lot more than pulling a lever and letting it go. We, at Winissimo Casino, have incorporated so many bonus features into its games, that indeed makes the gameplay more exciting and fun-filling. In addition to common ones like online slots with no deposit, here are a few you should expect from the best online slots UK like ours. 

Wild symbols

You must be familiar with wild symbols in video slots, but we assure you ours are wilder than you can imagine. At Winissimo, you’ll come across many types of wild symbols. A climbing wild symbol moved up one row after every spin, transferring wilds copy wilds onto other reels, extra wild symbols trigger multiple wild symbols in a single spin, walking wilds move one column after every spin, trailing wilds clone themselves on their way out, and sticky wilds stay on the reel for more than one spin.

Mystery symbols

You’ll find mystery symbols in many of our games. It’s mysterious in two ways: you don’t know which symbol it is, and you don’t know what it’ll change into. But when it does appear on the screen, it changes into a higher-paying symbol and multiplies your payouts. Bling!

Buy feature

There’s no doubt that bonus rounds are highly beneficial for players. However, they appear at random and on extremely rare occasions. This is why Winissimo has changed the way players enjoy bonus rounds. Now, you can trigger one at your own will. You can buy any number of bonus rounds, in certain games, with real cash and increase your chances of hitting the jackpot.


If you come across an online slot game with this feature, know that you’re in for some fun. A Megaways slot has six reels and pays in all ways. Thus, instead of the symbols appearing in straight lines, they can appear anywhere on adjacent reels.

Free slots

At Winnisimo, you can also try out slots for free to get a hang of the games and then play for real money. This free slots feature is indeed a big plus as it helps you understand the nuances of the slot game you wish to explore without having to make any deposits.

The common myths about online slots you should know!

Now that you have a very good understanding of online slots, let us look into some of the myths that are associated with online slot games. 

Slots function in the cycles of wins and loses

Online slots games operate at random. The results are generated by a Random Number Generator (RNG) that produces unbiased results that are completely random. 

Slots pay big

Slot games are solely based on luck and chance and their no particular determinant that influence the wins or payouts. 

The autoplay feature for spins gives you fewer payouts

A few players are of the opinion that slot machines take advantage of the players. But that is not at all the case. The autoplay spins feature, as well as manual spins, work with the same math and operate fairly and at random.

The operation RNG at Winissimo Casino: A sneak-peek

In the background of every online slot game featured at Winissimo Casino, there is a Random Number Generator (RNG) that generates thousands of numbers every second. Each of the numbers generated by the software is connected to different outcomes on the slot reels that appear when a player spins the reels. 

Let’s make it simpler for you! Here’s the process.

  • The players press the spin button and a random result is generated
  • The mathematical module in the games software translates that number or figures that appear on the reels. 
  • The reels instantly stop at random and the software calculates the result after the spin. 
  • Further, the players are notified about the result.

Well, there is nothing of such sort as the online casinos feature online slot games 24/7.
