An Introduction to Jewels of Jupiter

Something that’s interesting in the online slot world is that we have a lot of focus on Greek mythology. However, we don’t see so much of a focus on Roman mythology along with that. It’s so interesting because they are essentially the same set of gods with a different naming convention that’s largely based on astrological findings at the time.

Kalamba Games steps outside of the box to focus on the king of the Roman gods in that mythology.

With the Jewels of Jupiter video slot, you get a look into an ancient Roman temple to the king of the gods. Along these lines, the visual appeal is outstanding. This is a very aesthetically pleasing game with a great background in a Roman temple. The symbol set looks tremendous as well with a variety of influences from the source material.

The gameplay is particularly action-packed, and that all starts from the atypical format. You get an asymmetrical reel setup that changes during the free spins. Additionally, you’ll have tons of paylines and forced wild reels on every spin. It’s clear that they wanted to make sure that players got a lot of excitement out of this title. We have to say they did a good job with the way the gameplay elements are put together.

Betting and Layout

When you first take a look at this title, you’ll immediately notice that it has an atypical format. However, you shouldn’t be intimidated by it because it’s really easy to get used to. Here we’ll show you what you need to know to make sense of how the game is set up:

  • Six reels are used in this game. However, they are of different sizes as you can tell. The first reel starts off with two symbols. After that, they increase by one until you have the last two reels with six symbols each.
  • Despite the assymetical grid of symbols, you have a very straightforward 60 paylines. These lines cannot be changed in number. However, they work slightly differently in the free spins mode.
  • Paylines only pay from left to right in this title.
  • You can start off with bet sizes as low as €0.10. However, they also go up to the €50 level with lots of increments between. This helps you to really zero in on the exact bet size that is the best fit for you.

Every single payout listed in this game will be listed based on your total bet size. For example, if you have a wager of €1.50 and win a 10x payout, you’ll win €15. This avoids uneven and awkward numbers that would come from a 60-payline format.

The volatility of this title is actually in the medium-low range. A big part of this is that the hit-rate is above-average. However, the features being balanced help out with that quite a bit as well.

Gameplay and Features

The feature set for the Jewels of Jupiter online slot works out really well with the atypical format. We really like how Kalamba Games handled this. Additionally, they made sure the features make sense within the context of the theme as well. This creates a situation where you have a very immersive and cohesive experience.

Standard Wild Symbols

Players will find two types of wild symbols in this game. The first are the standard wild symbols that appear on each of the six reels. They come in the form of a golden rectangle, and they have some really good payouts.

  • Six of a Kind – 10x
  • Five of a Kind – 1.5x
  • Four of a Kind – 1x
  • Three of a Kind – 0.2x

These wild symbols are very valuable for helping with other combinations as well. The reason for that is that the paylines intersect a lot more in this title than others with a more usual type of format. That creates a situation where a single wild can end up on more paylines as a result.

Wild Multiplier Reels

A feature that really gives a lot of value in the Jewels of Jupiter video slot is the wild multiplier reels feature. On every turn, one of the reels is selected at random. A banner is thrown across that reel showing Jupiter’s lightning bolt. You’ll also see a value at the bottom that gives 1x, 2x, 3x or 5x.

The reel covered by the banner is treated as being filled with wild multipliers. The value for the multiplier is shown at the bottom of the banner. As a result, any winning combination that includes at least one of those wild multipliers is subsequently multiplied by that amount.

In the free spins mode, you’ll get three of these instead of one. The multipliers add up together for combinations that include more than one of them. Also note that these count for the wild combination payouts noted up above.

Scatter Symbol Payouts

One symbol that’s particularly important to pay attention to is the glowing electrified orb. It shows up on each of the six reels, and it is a scatter. The wins that it gives are somewhat flat, however, and they are as follows:

  • Six of a Kind – 6x
  • Five of a Kind – 5x
  • Four of a Kind – 4x
  • Three of a Kind – 3x

The reason these payouts are flat is that it’s much easier to get the three and four of a kind wins. It’s disproportionately easier because two of the reels only have two and three symbols each, respectively. Likewise, the last three have five, six and six. To compensate for this, the pay table for the scatters was adjusted accordingly.

Free Spins Mode

Three or more scatters anywhere on the game board activate a set of free spins. The first thing that happens is that the reels flip so that the larger reels are first instead of last. This drastically increases your chances of getting small and medium wins in this game.

The number of wild columns starts at one per spin. For each scatter you collect, the meter increases. Additionally, the further you get along the meter, the more wild columns you can have. You’ll also add free spins depending on how many you collect.

There’s another way to trigger the free spins with the HyperBonus feature. You’re given three options with the following prices:

  • 12 Free Spins – 71.3x
  • 10 Free Spins – 52.4x
  • 8 Free Spins – 35.7x

Note that the higher numbers of free spins are worth more proportionately because of the meter feature.

How to Win at Jewels of Jupiter

A lot of care was taken in this game to make the volatility pretty reasonable. It comes in just a bit below average. To this end, we suggest players pick a bet size around the average of what they are used to. However, you can also slightly increase your bet size if there’s an increment close to it.

This is available as a reasonable option specifically because of the volatility and high hit-rate. The swings get smoothed out a bit just because of that. However, you can enjoy slightly higher payouts at the same time.

Payout Structure for Jewels of Jupiter

The pay table for this game is extremely straightforward. You start with four gem symbols in different metal frames. They each pay out 0.8x for six of a kind. From there, the five card rank symbols all pay 0.5x. The pay table is so flat to compensate for the atypical format.


The gameplay experience in this video slot offers a serious amount of fun. We also want to point out that a good number of features are used in this slot, and that is something we can’t assume for much of the slots industry overall.

On top of that, as a portion of this developer’s offering of slots overall, this is a game that fills a critical position because it appeals to a lot of players. If you have enjoyed other titles that feature this kind of overall theme, then this is a video slot you will not want to avoid, and the presentation and aesthetic appeal of this slot brings an overall vibe that’s competitive with much that the online casino world overall has available.
