Slot machine details and review Sloteus Gold
Sloteus Gold, which was designed by Endorphina, is a slot machine with modern graphics and a theme that appears to be inspired by the Ancient Greek rulers. The focus inside is on King Sloteus and his treasures, while the slot machine theyβve designed for you has 5×4 reels with 25 paylines.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
A high volatility slot. Wins are rare, but can be really big. The game has more pronounced fluctuations and can often go without hitting anything for a long time, suitable for players who like adrenaline, higher risk and work with a larger budget. More about volatility here.
Slot theme and symbols
This slot from Endorphina delivers the right quality when it comes to graphics, being a modern version of what Ancient Greece looked like. It looks like the ruler mentioned in this 5-reel slot machine is based on the image of King Midas, but changed for the purposes of this particular story. There are plenty of gold-made objects on and off the reels, and you can see King Sloteus at the top, on a pile of gold coins. There are only 8 regular symbols used here, so getting new combinations formed shouldnβt be that difficult.
Sloteus Gold theme and symbols
While you may be able to form winning combinations with relative ease, this ends up being a High volatility slot, with lower rewards offered most of the time. To get paid a bit better, up to 2,500x the stake, you will need access to the main feature. Even though a lot of players will find it a difficult game to play, its RTP is 96.01%, and thatβs alright.

WILD symbol
As far as the wild symbol is concerned, itβs going to sport its own logo, so itβs easy to spot. The wild symbol is an expanding symbol, which takes over the entire reel, so it is part of all paylines. You only get it on the reels 2, 3, and 4, though. It will also not be a replacement for any of the feature symbols.
Scatter symbol
If you find the temple symbol with the Bonus logo, thatβs the scatter, and it can land on all reels. Getting 3 to 5 of these to land at the same time will pay 1x to 50x the stake, and will also get you into the free spins feature.
Free Spins
Via 3, 4, or 5 scatter symbols, the game grants you access to 10, 15, or 20 free spins. Youβre guaranteed an expanding wild for each spin, so forming winning combinations should be much easier.
Coin symbol
Coin symbols can appear on the reels, carrying prizes that range from 1x to 15x the stake.
Collector symbol
Collector symbols show up in the game as well, and they will be used to claim prizes from all Coins present at the same time.
Mystery symbol
Mystery symbols show up during the bonus game, and theyβre used to pay a random jackpot at the end of the feature. You can get either the 20x Min Jackpot, the 50x Mid Jackpot, or the 100x Max Jackpot.
Gold Hold Bonus Game
Whenever you have a minimum of 6 Coins and/or Collector symbols on the reels at the same time, you will get access to a Gold Hold bonus game. It can also trigger via the random Lucky Time feature if you have 1 to 5 Coins in view. This game plays via 5×4 reels, and you get three types of symbols to land (Coins, Collectors, and Mystery symbols). You start with 3 attempts, but the number resets if new symbols land (they become sticky as they do so). Fill up all 20 positions with symbols to claim an additional prize worth 1,000x the stake (Ultra Jackpot).
Risk Game (Gamble)
Endorphina included a gambling feature as well, but itβs entirely optional. If you want to risk a spinβs winnings, you can do so, using this card game that results in either a doubling of that money or a loss.

Our rating of the game
Sloteus Gold
Sloteus Gold has a decent range of features, using expanding wilds, free spins with guaranteed expanding wilds, and a respin feature, to deliver enough excitement overall. Unfortunately, once you look at its High volatility and the 2,500x top jackpot that can be claimed inside, itβs going to be a disappointment for plenty of players. The 96.01% RTP is fine, but I doubt it will save it. If you do want to check it out, Iβd recommend it for veteran players in particular.

How do we rate slot machines?
We evaluate slot machines based on multiple criteria, from which we make our final verdict.
Expanding wilds can help out with the formation of new combinations on all lines.
The free spins feature comes with guaranteed expanding wilds for each round.
Has a Gold Hold bonus game, involving respins with coins, collectors, and mystery symbols.
Decent-looking theme, with King Sloteus appearing to be inspired by the legend of King Midas.
There are OK long-term returns from it, based on the 96.01% RTP.
Cons
You can expect this to be a slot machine with high volatility, so fairly risky for the average player.
A 2,500x top jackpot is below average for a game where the volatility is high.
Individual combinations tend to pay little, at least most of them.
