Slotmill Review
By Alex Smith Feb 11, 2022
Verdict
Slotmill is one of the few gems out there when it comes to online slots. They are a relatively young company, but are run by some of the most experienced people in the business. They strive to have the highest RTP for available to players – which is really refreshing. I am looking forward to seeing Slotmill grow over the upcoming years.

Overview
Slotmill is one of the newest game developers to appear in the online gambling world and despite their relatively small size they’ve done a pretty good job – so far – of ensuring that all of their games are appealing to both players and online gambling operators. In this review we’re going to be looking at what this new software provider has to offer – and why Slotmill games are starting to feature at more casinos.
Slotmill was established fairly recently, and like many slot development companies they’re based in Sweden; their offices are in the nation’s capital, Stockholm. One of the main reasons why Slotmill’s games are so appealing to players is thanks to the fact that they tend to carry pretty high RTPs – averaging around 97% – and this is virtually unheard of in today’s online gambling industry that’s dominated by low RTP video slots.
Slotmill games also have a very strong attention to detail incorporated into them; not only do they look great, they all run smoothly, too. Don’t knock Slotmill for being a new game developer; they know what they’re doing (with some of their team having long backgrounds in the online gambling industry) and it’s likely we’ll see them continuing to feature at online casinos thanks to their high-quality games.
Software Platform
All Slotmill’s casino games and video slots are available to play on both desktop and mobile devices; this is because they’re developed using HTML5 technology. While it’s ultimately up to an online casino operator to ensure their mobile gaming facilities are up-to-scratch, Slotmill gives online gambling operators a good head start and they state that all of their games will be delivered in a size of 10mb or less. This makes them perfect for mobile gambling as they don’t take up much space – and it’s why, when we were putting this review together, we found that when it comes to new game studios, Slotmill is doing a heck of a job.
Slotmill Slot Games
Slotmill doesn’t have the largest selection of video slots (as you’d expect from a game developer that’s still relatively new) but the games they’ve released so far have gone down a storm with players – and their impeccable graphics, smooth gameplay and exciting bonuses and features make them appealing to all players. It helps that there’s some massive max win-potential on offer, too! Below, we’re going to take a look at some of the most popular slots Slotmill has developed so far.
Lucky Lucifer
Lucky Lucifer is one of Slotmill’s most popular video slots, and, as the name suggests, the game is themed around the devil, Lucifer. From the moment you first load up the video slot from Slotmill you’ll notice that the software provider really has spared no expense when it comes to making everything look as good as possible; the graphics are superb and all the imagery renders in full HD. The game is set on 5 reels and there’s some fairly decent win-potential to be found in the base-game, it’s fair to say. The major wins, however, typically come in the bonus round which is triggered by landing 3, 4, or 5 of the scatter symbols anywhere in view. During the bonus round you can win up to 666X your bet – so while it’s a far-cry from the 100,000X wins we’re seeing from other game developers like NetEnt and Pragmatic Play, it’s a nice little amount for most. The video slot also features a bonus buy option although this feature is no longer available for players from the UK.

Star Spell
Star Spell is another hugely popular game from Slotmill, and while it’s not offered at as many online casinos as Lucifer’s Luck, it’s slowly starting to find its way into more sites – and we expect it to continue rising in popularity as the software provider continues to grow. The game, as the name indicates, is set in outer space, and you’ll see HD star symbols appealing on the reels. During the base-game the action takes place on a 4-row, 5-reel format and you can play from between 0.1 and 100 credits per spin. There’s 10 fixed paylines and these are active at all times. The expanding wilds are the most exciting feature during the base-game, and they can land on reels 2, 3 or 4. When they land, they become sticky and a re-spin is awarded. If you manage to land another wild reel it will also stick in place and an additional re-spin will be awarded. This process continues until you land all three widls or until you fail to land another. Unfortunately, there isn’t a free spins or “pick me bonus” to be found in Star Spell, but there is a pretty nifty little bonus the game developer’s have built into the base-game; if you manage to land two sticky wilds your total win will be multiplied by 2X, while landing three wilds will see your win multiplied by 3X!

Vikings Creed
Vikings Creed is one of Slotmill’s more volatile video slots and this is seen immediately in the fact that it’s possible for players to win up to 5,000X their stake on the game. During the base-game there’s an identical mechanic to that we just looked at in Star Spell, and this sees re-spins awarded and multipliers activated when you manage to land wilds on the middle three reels. However, this video slot also has a free spins bonus round and this is triggered by landing three of the scatter symbols anywhere in view. Doing so awards 6 free spins and during these free spins any sticky wilds that land remind sticky for the duration of the free spins!

Vegas Gold
Perhaps the most popular video slot to come from Slotmills’ development lab, Vegas Gold is a 15-reel slot – yes, you heard correctly; 15 reels – during which 6 of these reels are unlocked when re-spins are awarded. There’s quite a lot going on, and this high variance video slot offers players the chance to win up to 5,000X their stake! Most of the action in this fast-paced video slot is found in the free spins bonus round which is triggered by landing two scatter symbols on the six reels that become unlocked during the re-spins. During the free spins, all 15 reels become active, and a 2X multiplier is applied to all wins to begin with. Each time you manage to form a win the multiplier increases by 1X and there’s no upper limit as to how high this win multiplier can reach! Vegas Gold boasts an impressive RTP of 96.36%, and this is a fixed RTP; it can’t be lowered at certain online casinos.

Thunder Wheel
Thunder Wheel is a very high variance video slot from Slotmill and it’s also one of their few games to offer win-potential of up to 10,000X the total bet; this Greek-inspired game takes place on a 4-reel, 4-row layout and there’s 256 betways active on every spin. There’s a mini feature present during the base-game, and this is known as the random wild feature. On any spin there’s a chance that any wild symbol that lands in view can expand – and the wild symbol can be as big as 3X3, ensuring some pretty decent wins! The main free spins bonus round is triggered by landing three of the scatter symbols anywhere in view, and during the bonus spins the special wild symbol is active on each spin; it roams around, changing positions on each spin. There’s also a special Thunder Wheel bonus round which can be triggered during the free spins bonus round and this is triggered by landing two of the wheel scatter symbols anywhere in view. You’re then taken to a giant wheel of fortune-esque bonus where you can win up to 9,999X your stake!

Wildfire
Wildfire was the first release by Slotmill in their ‘classics’ series – and, as you can probably tell from the name, the game differs from most online slots in that it’s not quite as volatile; in fact, Slotmill themselves state that it’s a medium variance game. The joker symbol is the wild symbol during the base-game and this, in combination with the re-spin feature offers up some decent win-potential in the base-game. However, it’s the Wheel of Free Spins bonus round that you’ll really want to aim for and this is triggered by landing a golden wild on each reel; you will then be awarded between three and ten free spins.

FAQs

What are some good Slotmill slots?
Naturally, what you like in terms of video slots may be very different to what other players like – so it’s pretty hard to give a firm ‘this is their best game’ when it comes to looking at Slotmill’s games. However, Vegas Gold is one of their most popular releases with players – and the high volatility places it well among some of the super high variance games we’re seeing released today. If you prefer something a bit more relaxing – retro, shall we say – then you may prefer Wildfire. This is basically a classic slot, although Slotmill has managed to build in a clever free spins bonus round, ensuring it’s fit for purpose in today’s online gambling industry!
What does left hand play mean?
Left hand play is a function that’s built into all Slotmill video slots; it means that when you’re playing one of their video slots from your mobile device you can spin the reels using your left hand; this is thanks to the fact that, when activated, the game screen changes and the spin and autoplay buttons are placed on the left-hand-side of the screen instead of the right-hand-side.
