The major constituents of online slots: A short glimpse

Today, there is an umpteen number of online slot games offered by all the premier online casinos operating across the globe. There is no doubt that the visuals, themes and gameplay of online slots are highly invigorating. Additionally, there are also attractive slot symbols that are one of the major components of online slot games. Let’s understand them in detail.

Broadly speaking, the online slot symbols can be categorised under seven heads. They are as under:

  • Standard symbols
  • Scatter symbols
  • Multiplier symbols
  • Wild symbols
  • Sticky symbols
  • Bonus symbols
  • Stacked symbols

Standard symbols:

These are the basic symbols of any online slot game. The Ten, the Jack, the Queen, the King, and the Ace are referred to as the standard slot machine symbols you will encounter most often on the online reel.

Scatter symbols:

Scatter symbols are another common bonus feature that you will find in most online slot games. Scatters are the rarer symbols on the reels and, therefore, they are harder to land. However, they have the advantage that they don’t have to be part of a payline to trigger their effect. The effect differs from one slot machine to another.

Multiplier symbols:

Multiplier symbols come under the rarer bonus features. They simply multiply your wins. Multiplier symbols can land on the reels just like any other symbol, but they increase the size of the payouts from winning lines 2x, 3x, 4x or even 6x times.

Wild symbols:

Wild symbols are undoubtedly a special type of bonus that is quite favoured by the vast majority of casino players. Most 5-reel online slots feature a wild symbol. It is usually listed in the paytable of the game. Wild symbols can stand in the place of any other character when the game checks for a winning combination. This means that they count as a joker.

Sticky symbols:

Sticky symbols are another new bonus feature. If you manage to land them on the reels, they remain fixed in place for several spins. Such a bonus is very beneficial for the player if the sticky symbol has some bonus properties.

Bonus symbols:

The bonus symbols are quite similar to scatters but trigger a special bonus game. The two types of slot symbols can interchange their functions. In other words, sometimes the scatters could trigger the bonus game, while special free spin symbols start the free spin rounds. In most cases, the bonus symbols are perfectly associated with the slot’s overall theme.

Stacked symbols:

Stacked symbols are a new invention that has been quite popular with slot players. Stacked symbols take larger space on the reels. They increase the odds of them becoming a part of a payline. Stacked symbols can be standard. In fact, some slot bonus rounds replace one kind of standard symbol with stacked equivalents. However, the most profitable stacked symbols have an added bonus.

Well, besides the above-discussed online slot symbols, there are other significant aspects too that constitute an online slot. They are as under:

  • RTP (Return to Player) rate :

 RTP plays a very vital role when it comes to online slots. RTP is nothing but the calculated payout of a slot machine. It typically ranges from 90-98%.

  • Payline :

 Also popularly known as the betting line or winning line, a payline is a combination of symbols that results in a win, on a slot machine.

  • Stakes :

 A stake is the amount of money risked or invested in the success or failure of a result in a casino game or outcome. It is also referred to as ‘bet’.

How do online slot games function? 

Every online slot game consists of a microcomputer known as the Random Number Generator (RNG) that generates numbers constantly, even when the machine is not being used. The RNG typically generates numbers between one to a hundred every second.

The Random Number Generator (RNG) exists of 1 and 0 that are calculated by algorithms. The combination of 1 and 0 decides what symbols and how they will land on the game screen. The algorithms are so advanced there is no way to determine whether the next spin will be a win.

One of the major highlights of RNGs is that the results generated by them are completely random and not biased. Hence, the players can be assured of authenticity and fairness throughout their gameplay.

The RNG operates in the following manner:

  • You click on the ‘Spin’ button. The RNG then generates a random number at a lightning speed.
  • The game engine of the slot uses this random number to calculate how each reel should stop.
  • Finally, the outcome is calculated of the spin and your total winnings are generated.

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.

Types of online slots

There are numerous types of online slots that are highly fascinating and enthralling given their mesmerising symbols, game design, themes and bonus features. Below are a few popular types of online slots discussed. Take a look!

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 are 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.

What Winissimo Casino has in store?

Online slots are a lot more than pulling a lever and letting it go.

Some of the most popular slot games that are a must-play include Beehive Bedlam, Irish Luck, Rainbow Riches and many more.

In addition to common ones like online slots with no deposit, here are a few you should expect from the best online slots in the 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.
