An Introduction to Zeus Wild Thunder

There’s no doubt that you’ll find a lot of Greek mythology-themed slots in the industry as a whole. It’s been like that since before online slots even existed. However, with the Zeus Wild Thunder video slot, SYNOT Games was able to make something that stands out instead of blending in with the rest of what the sub-genre has to offer.

This primarily comes from them creating a style of play that isn’t the same old thing.

First and foremost, you’re guaranteed a certain feature to trigger every 10 spins. That’s a big help to give you some great payouts and to smooth out the swings. However, the other features on the game board only add to that. As a result, you get an overall style of play that’s actually exciting instead of feeling like you’re playing a bunch of very similar titles within the Greek mythology sub-genre.

Graphically, this title is well above-average. The quality of graphics is on par with the top tier of what you can find online. With that said, it’s definitely drawn in a classical art style that won’t be anything new. Instead, it’s the application of that style that makes it look so good. SYNOT Games was serious about the presentation of this title being very solid. However, they also clearly wanted that to happen within the classical approach that’s often used for various types of mythology.

Betting and Layout

At the foundation of every slot is its basic format. That format can set the tone for the rest of the experience in a very serious way. Likewise, this developer used an action-centric layout here that starts you off with plenty of paylines. It also works as a great foundation for the feature set. Here’s what to expect:

  • The game board consists of a set of five reels, and you’ll have four horizontal rows for a 20-spot grid.
  • This grid is used here with 40 paylines, which is a nice and symmetrical number used with 20-spot layouts fairly often.
  • All paylines run from the far left to the right with no ability to lower the number of active lines.
  • Additionally, a pretty normal betting range is available here. You can actually wager as low as €0.20 per spin in spite of it having 40 lines.
  • However, bet sizes aren’t exactly limited either, and you can go up to €100 per turn as well.

The flexibility with the bet sizing is because SYNOT did not base things on line bet wagers here. Instead, when you see a win amount listed, that’s a multiple of the total amount you’ve bet. For a simple example, a 5x win with a wager of €2 yields a €10 payout.

Because of the way the game mechanics and pay table work, this game has a below-average volatility. We place it in the medium-low range. As a result, big swings will be minimal on average, and most of your play should be pretty smooth.

Gameplay and Features

In some slots, you can jump in and just figure things out as you go. However, we strongly recommend against that with the Zeus Wild Thunder online slot. One particular key game mechanic can cause you to get a lower return to player percentage if you don’t know how it works. Along these lines, we recommend reading through the following explanations so that you know how to avoid that problem.

Wild Lighting Ball Symbols

You’ll sometimes see a glowing ball of lightning on the reels. It’ll often come from the feature noted below. In any event, this is the wild symbol. It’s also tied for the best-paying symbols in the game with the following payouts:

  • Five of a Kind – 5x
  • Four of a Kind – 1.25x
  • Three of a Kind – 0.5x
  • Two of a Kind – 0.05x

The scatters will substitute for just about every symbol in this game. However, it will not substitute for the lightning symbol itself or the bonus symbol. Outside of that, it often helps to get wins that you wouldn’t have been awarded otherwise, which brings a lot of value to your experience as a whole.

The way wilds are figured into wins is based on evaluating each payline individually. This is important to understand because it can lead to some situations where you don’t understand how certain wins were calculated if you don’t. The game will look at each individual payline and determine how the wilds can behave to give you the single best payout for that line. However, sometimes a wild is at the intersection of multiple lines. This can lead to some cases where the wild will substitute in different ways for those lines at the same time.

Wrath of Zeus Bonus Feature

Observant players will have noticed the meter in the top-right corner of the Zeus Wild Thunder online slot. That meter is for the Wrath of Zeus feature, and it centers around the lightning symbol.

When the lightning symbol lands on any spot, it creates a glowing frame around that position.

The meter moves forward one position for every spin regardless of the result. However, at the end of the 10th spin, every single one of the spots with a lightning frame turns wild. The end result is that you have a chance for several wilds on the board simultaneously every 10th spin.

This feature is obviously where the name of the game came from. However, it’s also a critical part of the overall gameplay. Note that the meter and frames are preserved between bet sizes, so if you change your bet size, you’ll switch over to whatever meter situation you had with that size the last time you played.

Zeus Wild Thunder Free Spins

The middle three reels can have bonus symbols appear. These bonus symbols are the Temple of Zeus, and when you get all three at once, you trigger a free spins mode. However, you get to choose between three different options:

  • 15 free spins – Five forced wilds
  • 10 free spins – Seven forced wilds
  • 5 free spins – Ten forced wilds

Each spin will have a certain number of forced wild symbols placed on the game board. However, the meter will not run up during the free spins for the Wrath of Zeus feature. Additionally, you cannot re-trigger this free spins bonus round.

Between these three options, you don’t have to worry about a change in return to player percentage. The payout rate is the same for all three. However, the volatility is definitely higher the fewer free spins you choose.

How to Win at Zeus Wild Thunder

The overall average volatility of this title is in the medium-low range. Subsequently, you’ll have pretty tame swings that work for many players. However, some players may want to slightly increase their bet size by about 25 to 33 percent. The end result of this betting adjustment would be to move the volatility up a bit relative to the amount they’d normally wager.

This betting adjustment, which is completely optional, is good for players who don’t want a volatility that is so low. It will bring things up in line with what you see with an average volatility in video slots online.

Payout Structure for Zeus Wild Thunder

Zeus himself has the same payouts as the wild symbols noted up above. This comes in at a 5x win for five of a kind combinations. Like the wild, he also pays for just two of a kind. However, all other symbols need at least three of a kind for a win.

His wife Hera with brown hair and his daughter Aphrodite with blonde hair both pay 2x for five of a kind combinations. Four different symbols have 1.5x wins for five as well: the helmet, the harp, the vase and the green grapes.

SYNOT Games made the low-tier symbols’ payouts easy to remember as well. With the yellow A, red K, purple Q, blue J and green 10 symbols, you get 0.75x for five of a kind combinations.


The overall Greek mythology theme is utilized in a particularly smart way in the Zeus Wild Thunder online slot machine, which is different than it just being an afterthought like what we see in most games in the sub-genre. Along those lines, something players will really love with this game is the additional value that the selection of features add to your winnings. The play style of this video slot brings a ton of action with how those features tie into the mythological themes as well.

Because this game offers a high level of quality while still having a ton of value individually, this online slot fits really well in SYNOT Games’ portfolio overall. Also, we also like how the classic aesthetic appeal fits into the deity-based gameplay as opposed to just being a formality.
