Coming from industry veterans Microgaming, ‘Thunderstruck 2’ is a medium volatility slot game that has the same look and feel as its predecessor, ‘Thunderstruck’. The game sees you playing with the Norse gods of old again - Thor, Loki, Odin and more.
The biggest addition in the sequel is the exciting “Great Hall of Spins” bonus feature. This is a bonus spins feature that has four different levels themed after Norse gods and each offering spins and extra bonuses!
9 Pots of Gold
A game that is perfect for newer players, ‘9 Pots of Gold’ is an Irish themed slot from Gameburger Studios that came out in 2020.
Whilst it only features a small handful of bonuses and extras, the relaxed feel of the game will see players getting smaller wins more frequently. With this in mind, if you’re a player who likes to chase huge wins with intense gameplay mechanics, you may want to skip this one.
One of the most loved online slots of all time makes an appearance on the list. Join conquistador Gonzo on his adventure to find some Aztec gold in this game from NetEnt.
‘Gonzo’s Quest’ has been a fan favourite for many years and it’s easy to see why. It innovated the avalanche feature, has a great 15x multiplier, the animations are top-class and it runs silky smooth on mobile.
The Book of Ra
‘Book of Ra’ comes from Novomatic and - as you can probably guess - is themed around Ancient Egypt and Pharaohs.
The game has 5 reels, 10 different paylines and is jam-packed full of features. These include mystery symbols, special symbols that expand, multipliers and plenty of free spins thrown in to boot.
Another smash hit from Microgaming, ‘Immortal Romance’ has appeared on plenty of top slot game lists since it was released back in 2011.
If vampires and drama are your thing, then you’ll want to check this game out as it features a storyline that’s as epic as the vampire-themed hit film ‘Twilight’.
Aside from the storyline, one of the biggest draws of this game is the fact it has 4 different free spins bonuses and quite a high maximum win potential.
‘Mega Moolah’ from Microgaming is one of the most played progressive jackpot slot games out there. Earning the nickname of “the millionaire maker” in the online slots community, the biggest jackpot pays out at least €10 million.
This safari-themed game has four different jackpots for players to hit - Mini, Minor, Major and Mega - along with a huge 225,000 maximum coin win and 25 paylines.
If you’re big into crime capers and want a slot that has an interesting 1940s detective theme, ‘Private Eye’ is going to be right up your street.
This Microgaming slot is popular for several reasons - such as the 243 ways to win and 2-stage bonus round. The big draw though is how immersive it is. The amazing graphics and sound design suck players right into the storyline of the game.
‘Sunrise Reels’ is a solid online slot for players who want stripped-back, classic slot gameplay. The retro slot experience is the name of the game here, with pretty much no bells or whistles added.
You’ll find 3 reels, 5 paylines, traditional fruit symbols on the reels, a beautiful sunrise in the background… and that’s about it. The stripped-back gameplay is part of the charm of this basic slot game and why it’s been so popular with players.
‘Starburst’ is a classic from NetEnt and has long been a favourite for online slots players for almost 10 years now.
The bright, eye-catching graphics accompany the easy and fun gameplay - which is akin to a casino version of the hit mobile game 'Candy Crush'. Whilst it’s quite simple in its features, it remains a hit for both newbies and seasoned online slots players.
Playtech combines both simplicity and speedy gameplay with ‘Goblins Cave’, which will see you attempting to get your hands on a goblin’s loot.
The game has a simple 3x3 reel set up, only 3 paylines and one bonus round, making it easy for newcomers to get to grips with the game. Don’t let the basic features put you off though - you’ve got instant wins and the chance to get your RTP up to 99.32%!
