Play New Slot Games this 2024

Slots are an integral part of online casinos, and at Prime Casino, we aim to impress with hundreds of the best slot games available to play 24/7 on our site with just a few clicks of your mouse or taps of your touchscreen. At Prime Casino, we always pay keen attention to what the top developers have in the works as well as new or up-and-coming indie developers.

We add an unrivalled amount of new slots to our site every month, and we don’t just focus on the most hyped new release from a popular franchise, but also exciting lesser-known online slots which we know our players will love. All of our games (and our entire site) are completely optimised for play on all devices, meaning you can enjoy the best new slot games as soon as they are released.

When it comes to the new slots on Prime Casino, you’ll find a range of the most popular game systems from expanding reel slots with many ways of winning such as seen in Megaways slots, Jackpot Slots, and slots with jaw-dropping progressive prizes such as Jackpot King Slots. We even have slot games which bridge the gap between slots and bingo with our selection of Slingo Games.

What to Look Out For in New Slots

RTP & Volatility

RTP and volatility are important elements of any slot game, as they can provide an indication of how much the slot may payout (RTP), as well as how these wins tend to be formed (volatility). RTP is the expected percentage of wagers that a specific game will return to the player in the long run.  This information can be helpful for players choosing their next new slot to play, with some players enjoying high volatility action, and other casual players enjoying a lower volatility slot experience.

You’ll find information on the RTP and volatility of all new slots on the respective game page for the title. On average, standard video slots have an RTP (return to player) percentage of around 96%, while jackpot slots and fruit machine-style games will have an RTP that averages slightly lower, between 94-96%.


Different slots are designed to offer payout potentials designed to suit their theme, volatility rating, and so on. You can find useful payout information on the slots’ game page, as well as conveniently when playing the game via the paytable which is typically accessed by clicking on the ‘(i)’ information button. 

Most slots will automatically calculate the payouts for each symbol when the player enters their intended wager. Other slots will express the multiplier applied to the base wager value for example 20x or 300x. It is worth noting that in Megaways slots and other games which use cascading reels, paytable values may seem lower than traditional slots with prizes such as 0.1x on a low up and around 25x at the top end. This is because players can win multiple times from a single spin. 

Some symbols may pay for just 2 on a payline, and bonus scatter symbols may or may not have a payout prize (in addition to triggering bonuses). The top prize for a slot may be matched to the games’ theme, for example, 888 is a lucky number in Chinese Culture, while 7 is lucky in Western culture. The top payout potential may also be increased during bonus features, with a 2 or 3x multiplier being awarded during free spins, for example.

Minimum and Maximum Bet

All slots will have a wagering range which are the acceptable wagers for the game. This can be as low as 1p per spin, and while there are no theoretical limits on the upper threshold for wagering limits, most slots will have a top wager between £5-50 per spin, but there are those with accepted bets of £100 or more. 

It is important to note that some slots have fixed paylines, while others have unfixed paylines, and some have no paylines at all (such as cluster pays slots). You can view the payline structure in the information section of the slot. Fixed payline slots will have a set number of paylines, with the player's total bet being automatically equally spread across all paylines. 

Slots with unfixed paylines will allow the player to pick how many lines they’d like active, from 1 to whatever the maximum is. The wager entered will be multiplied by the number of lines the player has chosen to activate to form a total bet per spin.

Mechanics & Features

With thousands of slots out there, there are hundreds of unique mechanics and features used, but there are some which can be considered staples of the online slot genre, which we’ve summarised below:



Just like free spins, multipliers are a staple of online slots and you’ll find very few games which do not have some form of multiplier. In traditional slots the wild may multiply the value of wins it is formed in, or may have a global multiplier used across free spins. Some slots have multiplier wilds which have multiplier values attached to them and can be multiplied together if more than one is used. Some slots like many Megaways games can feature an unlimited multiplier which starts at 1x and increases with each cascade, before resetting to the original value when no further cascades can be made.



Wilds are probably the staple special symbol used in slots, with even the most simple fruit machines often having a wild symbol. Traditional wild symbols are special symbols which can stand in for all other non-special symbols to form a winning combination. Developers have experimented heavily with the humble wild over the years and have come up with variants on the symbol such as sticky wilds, expanding wilds, stacked wilds, multiplier wilds, walking wilds, and so on.

Free Spins

Free spins

It’s very rare that a slot will omit a free spins bonus round, in fact, it can be considered a design choice when a developer doesn’t include one. Free spins can come in the form of respins, a hold and win feature, or a traditional bonus where x amount of free spins are awarded to the player usually for landing three or more scatters within a single spin to trigger the feature. In many slots, the free spins bonus can be retriggered multiple times and additional free spins can be won.

Jackpot King

Jackpot King

As previously mentioned, some jackpot slots will boast progressive prize pots. The most popular system for this is the Jackpot King feature. The Jackpot King system is currently featured in over 40 Blueprint Gaming slots, and has three prize pots, the Royal Pot (which must be won before the pot reaches £3,500), the Regal Pot (must be won before £35,000), and the Jackpot King pot, which has no upper threshold and is usually millions in value.

Power Reels

Power reels

Power Reel slots infuse classic 5-reel slots with 243 pay line options. In a traditional slot format, 243 paylines would result in an expensive total bet per spin, but with power reels players wager per reel rather than per line. This allows players to maximise available paylines without breaking the bank.

Infinity Reels

infinity reels

This is a more recent innovation from developer Reelplay which is taking the slots world by storm. In Infinity Reels games, the reel set can expand theoretically limitlessly, meaning that playing on a slot with 12 or more reels is a pretty common experience in this type of game.



Every slot will have a jackpot, but for many, this is simply the top-paying combination possible when playing. Other games will boast fixed jackpot prizes, usually categorised as mini, midi, maxi, and grand, while others will use a progressive jackpot prize system.



This system is a staple of modern online slots, and first hit the market in 2017. A standard Megaways slot will boast up to 177,649 ways to win with each spin thanks to cascading reels and expanding reels.
