Understanding Online Slot Games
Before you can start playing online slot games, it’s important to understand all the fundamentals. Knowing the basics, will help you in both managing your funds, minimising your risk, and enjoying gameplay.
Whether you’re playing multi-slots, or basic 3-5-reel slots, the structure is pretty much the same. So, let’s get down to the nitty gritty.
Online Slot Games Terms
Demo or Free Play: Some online slot games offer the option to test the online slot game without the risk of losing any of your real funds, the options are given to players as either ‘demo or free play’.
Balance (Cash & Bonus) — Can be displayed as total balance including amount deposited as well as slot bonus included if you qualify.
Alternatively split in two; ‘cash balance’ amount you have deposited or won that’s withdrawable or ‘bonus’, amount of bonus funds earned or rewarded for use.
Some online slot games will display a slot bonus balance, however once you decide to play a game, may show as ‘insufficient balance’. This is because they require you to make a qualifying deposit that will enable the slot bonus to be earned.
Pop up notification box — Generally displayed below the actual slots or at time above. Any winnings you have will be displayed here each time and then automatically added to your balance.
Paytable — This is a simple indication table, which clearly displays all the symbols within the reels each time you spin. The symbols will indicate what the payout is each time you draw several matching symbols or the bonus symbols.
Reels — Individual spinning columns of symbols within the slot machine that expose themselves, upon each spin.
Bet per line — The amount of money you would like to wager per line, the more available lines, the more money you wager, however the greater the chances of a win and payout.
This will generally appears as either a ‘+ or –‘ or at times ‘^ or v’ symbols. Aside from your general bet, you can increase the amount of each bet per line.
Number of paylines — Similar to the bet per line, however the number of paylines indicates how many lines you want to have active along the reels the more active paylines the higher the chances of a payout.
Maximum bet — Each bet per line or payline has a max amount you can wager on; this is due to the max amount the online slot will payout should you hit the jackpot. Therefore, bet per line multiplied by the number of lines = maximum bet
Play/Spin — When you’ve configured the amount you’d like to wager per line as well as number of lines you’d like active, the next phase is to play or spin the reels, this is generally indicated using a flashing ‘circular’ symbol or a ‘spin’ button.

Online Slot Games Explained
There’s just something about online slot games that we all love! The bright lights, the catchy jingles, the spinning and the winning that keeps us wanting more!
Throughout history online slot games have always been popular, and game providers there’s literally thousands of different themed online slot games with hidden bonus rounds and prizes to keep you entertained.
Whichcasinos.co.uk has trawled the big wide web to find you the best online slot games sites, to give you the best possible experience!
The Birth of Slot Games
One of the most popular forms of gambling is of course Slot Games. With the first slot machine invented in 1887 by California based Charles Fey.
Although most believe that Charles completed the first slot machine in 1895 this was because the first slot machine was much simpler. It consisted of three spinning reels containing a total of five symbols, Horseshoes, diamonds, spades, hearts, and a bell (Liberty Bell), from which this machine took its name.
By replacing ten cards with five symbols with three reels instead of five drums, the complexity of reading a winning result was significantly reduced, allowing Fey to develop an effective mechanism of automatic payment.
Three bells in a row produced the biggest reward.
Mills, Takes Slot Games a Step Further
in 1907, manufacturer Mills from Chicago produced a slot machine known as the Operator Bell. A year later many “Bell” machines were installed in most cigar stores, saloons, bowling, brothels, and barber shops. The original Liberty Bell machine can still be seen at the Liberty Belle Saloon & Restaurant in Nevada.
Playing online slot games today
Online slot games are hugely popular which is why game providers bring out so many different themed games ranging from Starburst, Gonzo’s Quest, Cleopatra or licensed games like Jurassic Park or Guns N’ Roses.
All of the online casinos that whichcasinos.co.uk choose to vet and list, have lots of variety from the classical slots, set jackpots and progressive jackpots.
You can demo most online slot games first as well to see if you like them, but the real beauty is that you can play anywhere on any device. Online slot games don’t have to cost a lot of money either. You can win hundreds or even thousands from spins that are worth less than £1.
With so much variety you’re sure to find one you like and hopefully get lucky on!
Variation in Online Slot Games
There are 4 variations of slot games available to choose from for those want to play, these include:
Classic slots tend to follow a similar pattern, and may include one or all these features:
- 1-5 paylines
- 3 reels
- Fruit symbols/BAR symbols
- Minimal slot bonus features
- Trail slot bonus
It is of no surprise that given the history of Slots, there are still slot games enthusiasts that prefer the entire experience seen when playing actual slot machines. From the well-known leaver, to the colourful symbols and sounds.
As a result, online slot games operators have tried to replicate the feeling online, the result is classic slots. Some examples of classic slots include:
- Jackpot 6000 (LeoVegas)
- Mega Joker
- Fruit Slots (Betway)
- Goblins Cave
- Ugga Bugga
Like most other online slots, Video Slots work in the same way however are even more popular with players who prefer action-packed gaming with slot bonus features and side games.
Video Slots offer a more immersive experience and allow you to be a part of the action through interactive slot bonus features and detailed animations.
When comparing video slots to the slots found in land casinos, online video slots are easier to understand and play.
In addition, video slots also offer a wider variety of combinations than those found in land-based casinos, generally seen with symbols A-K-Q-J, 6, 7, 9, 10 with an additional symbol usually with the word ‘wild’ or ‘scatter’.
The symbols are usually based on the name or theme of the online slot game you’re playing. The maximum wager when playing video slots is 100 coins, but you will often see 300, 400 or 500-coin maxes on casino slots.
Although general casinos only have one bonus feature, video slots offer multiple slot bonuses giving you more chances to win bigger.
Important Points to note Prior to Playing Slots
- Matching symbols across all reels is not necessary the only way to win money.
- Amounts won vary, therefore winnings can be lower than the initial wagered amount.
- What you win is proportionate to how much you have wagered, with no slot bonus for betting the max.
- Understanding the online slot games return to player (rtp) percentage increases chances of winnings, although always remember our second point.
Understanding Slot Game Paylines and RTP
All the above points are important to understand when playing video slots, especially for a better experience. When playing a five reel video slot, players do not have to line up matching symbols across all five reels. Instead you will win money by having matching symbols across reels 1,2 and 3, if 4 and 5 are added them you win big.
Slot Games – Return to Player (RTP)
It is important to understand the online slot games variables or rtp percentage. The rtp percentage can be found by clicking on the slot games information. A high rtp percentage is indicated from 97% – 99%, the higher the percentage the more often the online slot game pays out.
Therefore, the more you stake the higher the chances to win big when you hit the slot bonus.
Video Slot Games – Paylines
Another great feature offered by video slots is multiple paylines, this is because a player can have multiple winnings from one spin should a variety of symbols and characters are activated across the reels.
For example your first three reels all align with J,J,J your second row consists of 2 wild symbols and a character, while the 3rd row has a wild symbol with reels 2,3 and 4 displaying similar characters.
You would therefore win across all 3 rows or however many qualified for the payout. Below is a breakdown of the multiple paylines and all the factors for a clearer understanding.
Video Slots – Multiple Paylines
Wild symbols and expanding wilds – Wild symbols are matches for any symbol, usually excluding scatter symbols or slot bonus symbols.
Scatter pays – Scatter pays do not have to line up on any payline. On many slot games, bonus symbols are scatter symbols. So that if you get three of them anywhere on the reels, you launch the slot bonus round.
Bonus events – Slot bonuses can be free spins, pick-a-prize, wheel spins or scratch cards.
Now that you have a good idea of what video slots are as well as what to look out for, here is a small list of some recommended online slot games you would like to have a go on:
- Nemos Voyage
- Return of Kong
- Fishin Frenzy
- Book of Dead
Mega Spins on Video Slots
As we have given you an indication of what classic and video slots are, Mega Spins are a combination of the two, but on a larger scale. Released by giant software provider, Microgaming, Mega Spin Slots follow your modern-day Vegas themed slot machines.
Never been to Vegas to see one? Well no problem! Imagine the video slots reels 4-6 rows with 3-5 reels, now imagine having that screen duplicated 4, 6 or even 9 times within one screen!
This mega combination of multiple reels linked to the major millions jackpot system, means, should you win, it is generally a life changing amount of money.
The reason to the gigantic size on the jackpot is because it is a progressive jackpot. This means several different participating casino providers will put all player losses back into the jackpot and will continue doing so until the jackpot drops. Your chances get bigger and bigger with every new three-reel game activated on the screen
Although the Mega Spins looks daunting at first glance, the characters and symbols used are like those seen on all online slot games.
There are 4 variations of the Mega Spin Slot games available for you to play, these include:
Mega Spins – Double Magic

Thanks to a multi-format game mechanics, your winning chances and payout amounts are much bigger compared to traditional games, which creates a brand-new gaming experience.
High 5’s – Mega Spins
The High 5 Mega Spins video slot is organically a classical slot machine with an extraordinary mega spin feature enabling you to experience more gambling action by spinning nine slots at once. On top of this, you stand the chance of hitting a massive jackpot of 15,000 coins.
Mega Spins – Major Millions (Progressive)
Major Millions is a must-play for progressive jackpot slot seekers and three-reel slot fans. In addition to the massive progressive jackpot to be won at least once a month.
The game features classic symbols, wilds, wild multipliers and 6 three-reel machines played on a single screen at once.
Progressive Jackpot Slots
As the name indicates, Progressive Jackpot Slots, are different to regular online slot games, whereby a set amount of prize money to be won is displayed.
Instead a Progressive Jackpot Slot is one that indicates to continue increasing until it is won. Therefore, any player playing the Progressive Jackpot Slot and loses will see their lost cash added to the giant pot.
Surely there cannot be that many people playing a progressive jackpot slot to warrant the amount of money on display to be won, right?
Well when you think about it that way, you are right, but it does not work the way you’re thinking.
As you know, there is thousands of online casinos available, and majority of these online casinos will have the popular progressive slots on their website.
Therefore, every player on every website playing at any given time that loses sees a percentage of their cash go into the one giant prize fund!
In-house Progressive Jackpot Slots
In some cases individual online casino brands will have their very own Progressive Jackpot Slot game whereby they put an initial amount of money into the pot to start it off, however the larger progressive jackpot slots are where a number of online casino come together.
Some progressive jackpots work across titles, for example, ‘Marvel Slots’, whether you’re playing Hulk, Spiderman, Avengers or any other of the Marvel Jackpot Slots, a percentage of the player loses are taken from all the individual titles and added to one big prize pot.

There is no question though, that the Mega Moolah progressive jackpot leads the way in terms of payout, and it drops at different amounts, ranging from €8,000,000 to €18,000,000 so far.
What do I have to do to increase my chances of winning the progressive jackpot?
The truth is it is gambling, and there is no rightful answer to the above question, however there are two main point to remember, likely to give you a better advantage:
- Depositing and playing with higher amounts increase your chances to winning big, this is not necessarily dropping the jackpot, however winning large prizes with other combination of symbols. Most jackpots increase the chances of dropping the bonus if a qualifying deposit amount is being wagered.
- Regular play, online casinos are equipped to monitor regularity of play, therefore the more you play, the likely you are to increasing your chances of winning, again this might not be the jackpot, but other good cash prizes.
