The first decides if you can grab a tasty wad of cash, the second if you have lots of fun competitions to enjoy in the long run and the last of course is where the actual day-to-day fun of playing comes in.

Finding the hottest slot releases

Slots games are typically produced by a third-party slot provider, or made in-house by certain casino sites, such as Nektan. In either case, there’s a fairly constant stream of new games being released, which gradually then filter out to casino sites.
When you check out a new UK slot site, the best result is to find some brand-new games to play- either the latest releases, or games from a provider you haven’t encountered before. The hottest slots at the moment are coming from major developers like NetEnt, Microgaming and Yggdrasil.
Yggdrasil lattest game is GigaGong GigaBlox, an Asian themed slot with 6 reels, 4 rows, and 40 fixed paylines, featuring the unique GigaBlox mechanism. Players can adjust bets from 20p to £400 per spin, catering to various preferences. This game boasts an RTP rate of 96%, though be aware some versions may have a lower RTP. It offers a maximum win of 5,120x your stake and features a Gong symbol that triggers a global gong multiplier. Additionally, the free spins feature activates with 6+ scatter symbols and offers extra free spins for each additional scatter. Compared to other Yggdrasil titles GigaGong GigaBlox's visuals are underwhelming and its gameplay is relatively mild. It is still a decent choice for fans of the mechanism but lacking the innovation found in similar games like 90k Yeti GigaBlox or Water Blox Gigablox.

Variety is the spice of life

Dungeons and Dragonsis one of Microgaming’s latest hits, invites players to journey into the heart of a dragon's lair in pursuit of gleaming gems, promising instant wins, multipliers, wilds, and more.  This 5-reel, 40-payline slot has a visually appealing fantasy-themed design, featuring heroic characters and a slumbering dragon amidst a backdrop of gold. The gameplay offers free spins and fixed jackpots, with user-friendly controls located at the bottom of the screen. With a RTP of 96% and high volatility for the potential of larger, less frequent wins, the slot's maximum win caps at 5,000x your stake through the Grand Jackpot.
One of NetEnt’s latest slots is Superstars. Launched in October 2022, this slot has 5 reels and 5 rows, offering a total of 45 ways to win in a single round.  The game features beloved characters from previous NetEnt titles, including Gonzo (from Gonzo’s Quest), Lady Pig (from Piggy Riches), Brute (from Space Wars), Finn (from Finn and the Swirly Spin), and the Star (from Starburst).
'Superstars' offers extra spins, an extra life, bonus games set on a 'Monopoly board,' a wheel game, and a final game. The RTP rate is over 96%, and this game boasts stunning graphics and the potential to win up to 4596 times your bet.

Playing the latest slots on mobile or desktop

Modern slot sites tend to have top quality mobile access. This is because new sites are built with different types of access in mind from the start, where some older sites are struggling to convert. More than half of internet use is through mobiles now, so casino sites are moving with the times - another big plus to joining the hottest new slot sites as they open.
These sites can be accessed on mobile phones or tablets simply through the browser, loading a condensed version of the site. Sometimes a few games may be omitted if they haven’t yet been upgraded with touch-screen controls, but this is no concern for new games.

Many new UK slot sites go a step further by offering dedicated apps for iOS or Android devices.These apps can be easily downloads from the App Store or Google Play.

All the latest slot games are mobile friendly, with intuitive touch-screen controls; just tap to spin the reels or access the paytable.

All the latest slot games are designed for mobile users, so you will find touch screen controls, letting you spin the reels with a tap. Information like the paytable is found with another tap button, or by swiping left or right.

Claiming bonuses at new slot sites

Always keep an eye as to what is on offer at new UK slot sites. There's no limit to the number of sites you can join, so it is worth looking at the site’s welcome bonus for newcomers.

The welcome bonus is usually the first pit stop for someone joining a new slot site online. This will be a cash match on your first deposit. New slot sites tend to offer high percentages to make them stand out from the crowd, such as 200% or more, meaning that a £10 deposit gets a £20 bonus.
This generosity is sometimes balanced out with higher wagering requirements, so always read the terms and conditions closely. Typically, players are expected to play 40x whatever they get in bonus money. This obviously is a lot of money, so you have to win quite a lot to get a withdrawal out of your bonus cash. On the plus side, each small win is helping you to breeze through this amount.
Some slot sites also offer free spins. These are typically attached to one slot or a group of slots by one provider, so it’s worth checking that it’s a game you fancy before signing up. Still, this is a great way to get stuck in with a new slot game. Winnings from these will also probably have wagering requirements.
Don’t forget that it’s worth checking the whole promotions section for offers, as some may be available that aren’t part of the welcome package by default. For example, some sites offer cashback or free spins on certain days of the week, so it could be your lucky day. It’s also good to know if the site offers a lot of specials or regular events, to judge how much you’ll get from the site in the long run.

What type of games are found at new slot sites?

There’s quite a bit of variation in slot games, which you will see all the more if you join a lot of the new slot sites appearing online. Most slot developers dabble in various slot types, using varying gameplay elements that affect how the slots play out. The more developers a site uses, or the more sites you join, the more mixture you will see.

• Five-Reel Slots: These are the most common slot and are the standard, striking a balance between variety and screen space. However, classic three-reel games reminiscent of arcade classics are also available, which offer a more relaxed gaming experience.
• Win-Both-Ways Slots: These slots allow wins to be counted from either edge of the reels, enabling winning combinations from right to left, not just left to right. One of the most renowned examples is NetEnt's Starburst, featured on numerous top slot sites.
• Progressive Slots: These games feature substantial jackpots that continuously grow with each bet placed. A small portion of each bet contributes to the progressive jackpot, leading to rapid and substantial increases. Progressive slots have the potential for life-changing wins.
• Bonus Features: Most modern slot games incorporate bonus features, which can range in complexity. Expect to find anything from simple free spins to expanding wilds and fully animated bonus rounds with mini-games. Progressives are usually won through a bonus.
