Online Slots FAQ
How To Win Playing Slot Games Online
Wins in online slot machines come in various ways. Matching symbols along paylines is possibly the most simplistic method, but there are a range of new mechanics, including clusters, Megaways, and bonus rounds that can prove valuable as well if you win!
Popular Bonus Features Include:
If you’re ever in doubt about a game’s features, you can always navigate to the game’s menu to find out more information regarding symbol values, paylines or bonus features.
Are slot games REALLY random?
Unlike table games such as poker and blackjack, there’s very little inherent skill involved in playing online slots. Game providers utilise a system called a ‘Random Number Generator’ on every single spin to determine which symbols are displayed. The use of RNG ensures that each player has the same chance to either win or lose on every spin.
What is RTP?
RTP stands for ‘Return to Player’. This is a universal metric across the slots industry and gives a mathematical indication of how much return a player can expect from a prolonged period of play.
Whilst a game may advertise its RTP as 96%, indicating that if a player played £100 worth of spins they should expect around £96 in returns; it’s important to understand that RTP is calculated as an average across a large number of simulated spins and it’s entirely possible for an individual player across a play session to both return more than 96% or much less.
If you are unsure about a game’s RTP, the value is often displayed within the game’s menu.
Is there any way to increase your chances of winning on slot games?
A question that often occurs from players is ‘how can I increase my chances of winning on slot games?’. In short, there are no ways to affect the outcomes of your play. The Random Number Generator discussed above ensures that gameplay is completely random and is not open to manipulation from players.
However, despite this, there are a number of tips that can be employed to help make your play session last longer. The first and most basic is to always play at an appropriate stake limit to your budget. Slots offer a choice of how much you wish to stake per single spin, ranging from £0.20 or less up to £20 and occasionally higher. Whilst larger spin values can naturally result in larger wins, this can deplete your cash balance quickly. Many bonus features have a low probability of triggering, therefore playing at a smaller stake amount, whilst not guaranteed to trigger a bonus feature, will allow more spins and in turn increase the probability of triggering the feature, albeit at a lower payout.
How do I know which is the best slot to play?
There are lots of different factors to consider and questions to ask yourself when choosing which slot to play. First, how important is the theme or genre to you? The theme is made up of the aesthetics, sounds and even symbols present within the game. For example, if you fancy an Irish-themed slot, you may wish to check out Rainbow Riches, or alternatively, if you’re in the mood for an Egyptian-themed slot, you may be inclined to check out Eye of Horus.
If it’s mechanics you’re after, then look no further. We have everything from Slingo Rainbow Riches and Fishin’ Frenzy Jackpot King to Reel King Megaways and Bonanza. Take a look at our casino games page to find out more.
Alternatively, you may wish to make your choice based on the max payout or multiplier. Each game has a unique maximum payout or multiplier, which can be found within the game’s menu. If you’re looking for big payout slots then you might consider Return of Kong Megaways or Who Wants to Be a Millionaire Megaways
Don’t forget you can always test run a game by playing the demo mode to see if it’s up your street before wagering real cash.
Are there any online slots that are good for newbies?
New to slots? There are plenty of games which might appeal to you as you’re learning the ropes. Immortal Romance is a fan-favourite on account of its simplistic yet engaging gameplay. There’s very little in the way of bonus mechanics and the straightforward symbols and paylines make it a top choice for new players.
For those new to the world of online slots but familiar with traditional pub fruit machines, there are a host of pub fruits which have migrated from the pub to the internet! Games like 7’s on Fire provide a familiar gameplay experience for players who enjoy traditional fruit machines.

What are the best slots to play online?
With such a huge range of slots available to play at Slot Boss, selecting one to play can be a difficult choice - luckily, our team of casino experts are on hand to help you!
If you’re looking for a real casino classic with a modern graphical appeal and a fantastic range of bonus features, you should look no further than Red Tiger’s Piggy Riches Megaways. Offering the chance to bag some huge wins alongside the timeless theme of NetEnt’s original Piggy Riches, this casino slot has proven a real hit with our players.
If you’re looking for something a little more lighthearted and cuddly, you may want to check out Fluffy Favourites. Featuring the lowest minimum stake size at 1p per spin as well as the potential to bag a nice 100x return in the Toy Box bonus feature, Fluffy Favourites has become a fan-favourite for good reason.
On the spookier side of the spectrum, Book of Dead is a mainstay of most brick and mortar casinos as well as their online counterparts. New players at Slot Boss can unlock up to 10 Free Spins on Book of Dead. With its engaging range of features and reputation as a cult casino classic, it was a no brainer when deciding which game to offer our new players free spins on.
Which online slots payout the most?
If you’re wondering which slots offer the highest payouts, there’s a couple of things to consider. If you’re looking for huge progressive jackpot slots, Jackpot King slots offer players the chance to trigger the Jackpot King Wheel on any spin of any value. These jackpots range from the thousands of pounds right up to the millions - could you become a slots millionaire off a single spin?
The other way to potentially bag a huge win is by playing a large multiplier. Games such as Starburst feature a maximum multiplier of up to a massive 50,000x your stake, while the ever-popular Monopoly Megaways, through its bonus feature, offers players the chance to win up to 14,700x their stake to a maximum value of £250,000!
What are paylines?
A payline, in its simplest terms, can be described as a ‘winning line’. The value of the win can depend on the symbols present or even the order they appear on the reels. The first physical slot machines featured three rows with a single reel and offered a single payline, which simply required players to match three symbols on that row, with the payout determined by which symbols were matched.
Slots have evolved massively since this time, adding further complexity to the humble single payline slots of the past. The extra reels found on many of today’s slots have increased the number of available paylines; where in the past, matching three symbols in a single row returned the player a win, nowadays it’s common to have paylines in a variety of shapes such as diagonal, triangular or diamond,
You can always view a game’s menu to find out information about its paylines and symbol values.
If you fancy something a bit different from online slots, you can also play a range of classic casino table games like Blackjack, Poker or Roulette. For those of you seeking live play, try Lightning Roulette, Crazy Time or Monopoly Live
