Stellar Portals Review

The niche of space-themed slots consists of hundreds if not thousands of titles from different developers, though, none of them seem to stop releasing more and more examples to complement the niche. Undoubtedly, the most successful by far is NetEnt’s Starburst, which has inspired a countless number of games, which not only use its design as a development vector but also implement its mechanics in their own slots.

However, Stormborn Games with their Stellar Portals slot seem to be the guys who love to break patterns and think of their own innovative ideas. Stellar Portals is the third game to supplement the developer’s portfolio, and even though the studio is new to the market, they have already managed to attract some players thanks to their unorthodox approach to the game development. So, let’s find out whether their brand new slot will be able to surpass their previous releases and will follow the footsteps of the success of the most influential slots in the niche.


Stellar Portals - Technical Info

The actions take place across a common 5x3 layout with 20 ways to play. Stellar Portals is powered by a high volatile math model, so you’ll have to manifest patience waiting for big wins to come. Nevertheless, thanks to the moderate hit frequency wins will occur fairly often to keep you afloat. The RTP is also solid at 96.04%, which is slightly above the average level within the industry.

Playable from 0.2$ to 20$ per spin, Snowborn’s brainchild comes with a decent potential indeed. You can hit the jackpot of up to 7,777x of the bet in Stellar Portals. Taking into consideration the betting cap of 20$, all high-rollers can hope for a win of 155,540$ on a single bet when playing with the max bet option available.

Stellar Portals - Design and Symbols

As alluded to earlier, the game uses a space theme, and true to the style, the reels are set somewhere in deep space, floating through the endless void. The game actually looks pretty nice as the bizarre patterns with iridescent colors make up the backdrop. The soundtrack adds a final touch to the immersive atmosphere and fits the gameplay perfectly as an electronic beat plays whilst you spin the reels.

The symbol collection is a set of 8 regular symbols, split in to high and low. All the symbols are represented by weird extraterrestrial elements. At the low end, the paytable starts with blue, green, yellow, and red shiny icons. They are followed by 4 premiums, which actually remind colorful either blackholes or contacts, though, as the title implies, the premiums are represented by the portals. They also come in 4 colors, including blue, green, yellow, and red, with the last one looking like Mangekyou Sharingan indeed.

You’ll require at least 3 symbols on a line to score a win, and the highest payouts are given for 5-of-a-kind combos. Stellar Portals is pretty generous with the payouts, as the premiums start from 6.25x for 5 instances of the same symbol, and the top-paying one is worth 75 times the bet. The lower valuable ones are worth from 1.5x to 3.75x of the bet. There are also 2 kinds of Wild symbols included in the game, which both act as substitutes for any other regular symbols and are worth the same as the top star here.

Stellar Portals - Bonus Features

When it comes to the bonus features, that’s where Snowborn Games can really impress. The devs saturated the gameplay with a huge list of features to keep you entertained both in the base and the bonus games. In case your first thought about Stellar Portals was ’another bonafide copy of Starburst’, after looking at the paytable you’ll definitely change your mind.


As referred to above, the game boasts 2 Wild symbols. The first one is regular, which can appear on any reel on any spin to assist you in making winning combinations or enhancing already existing ones. The second one is Sticky Wild, which acts as a regular Wild symbol and at the same time is a key to triggering the Respins feature on top of everything. Whenever you land a Sticky Wild it remains in its position and awards 1 Respin, and the Respins continue up to the moment when no new Sticky Wilds appear, so it’s possible to get more than one consecutive Respins on a single spin.

The Free Spins is certainly the heart of Stellar Portals as it includes various Free Spins modes, with each one having different extras. There are 4 different modes in total, and each one is triggered with the help of the corresponding Scatter symbols, which can appear on the reels 1, 3, and 5.

  • Multiplier Bonus: landing 3 Multiplier Bonus Scatters will trigger the Free Spins feature with the multiplier of 5x, which will be applied to every win you manage to score during the feature. It awards a random number of Free Spins from 6 to 9, and you cannot retrigger the feature.
  • Rising Multiplier Bonus: land 3 Rising Multiplier Bonus Scatters to trigger the Free Spins round with a progressive multiplier. You’ll proceed to the bonus game with 6 Free Spins, and at the beginning of each spin, the multiplier will rise from 2x on the first spin to 10x on the sixth spin.
  • Stacked Wild Bonus: 3 Stacked Wild Bonus Scatters will trigger the Free Spins round featuring Stacked Wild symbols. You’ll get from 6 to 9 spins, which is determined at random, and during the feature Stacked Wilds can appear on any reel.
  • Sticky Wild Bonus: land 3 Sticky Wild Bonus symbols to get 6 Free Spins featuring Sticky Wilds. Whenever a Wild symbol lands onto the reels during the bonus, it remains in place for the duration of the bonus, however, it cannot activate the Respins.

The 200 Spins Experience

The very saturated gameplay immediately caught our attention so that we couldn’t go over without giving it a try. We had really high hopes set for Stellar Portals since the rich gameplay features paired with decent payout potential were extremely promising. One point to mention is that 200 spins are not enough to provide any accurate statistics, so don’t expect to see any analytics with tracked patterns of strategies of how to play and win in this game for here we’ll just express our subjective opinion on the game based on our personal experience.

With the bet set for 1$ per spin and a great level of enthusiasm, we enabled the autospins mode, leaned back on our chairs and started patiently waiting for the action to begin. However, the day was ruined after the first 100 spins involved more than a half of dead spins, and the only tasty Big Win we managed to land was 12x of the bet, which couldn’t save our bankroll from rapidly decreasing to zero. We did expect a drastic improvement within the next 100 spins, however, we failed to get anything higher even than 12x of the bet, and looking ahead, it was the one and only Big Win within the 200 spins test. The bonus eventually popped up after a countless number of spins and did give us a little morale boost, but didn’t manage to get us close to breaking even. The feature ended up with a 15.85x the stake win, and we returned back to the base game with only 50 spins left to help us get our returns.


As you might have already thought, nothing magical has happened, even though the same bonus appeared again, but resulted in a ridiculous 0.65$ win. The total loss of the session was something around 100$, and oddly enough, we didn’t even take effort to recoup. As you can see, that was unpleasant, however, every session is unique and the outcomes are never the same, so we wish you more luck and hope that you hit some sweet jackpots.

Stellar Portals - Verdict

Snowborn Games in conjunction with their partner studios Microgaming did a great job of developing Stellar Portals for sure. Even though the game comes with a pretty cliched and jaded theme, it manages to make a standout from the niche thanks to the authentic feature set that will certainly keep you in the right mood during the session. Though, let us lay this in order.

The first thing that catches the eye is obviously the game’s appearance. Not to say that it looks bad or smth, but we’ve seen a lot of better-designed games so far. As has already been mentioned above, it uses a rather common theme and the influence of Starburst can be seen with the unaided eye.

Nevertheless, it’s not appropriate to compare the games when it comes to the in-game features. Snowborn Games has not just included an enormous list of features, but they’ve made them work perfectly. Despite the fact that Stellar Portals is a highly volatile slot, wins as well as the features pop up fairly often, and almost on 9 out of 10 spins Wild symbols land onto the reels, assisting you to get decent payouts. Even though landing Sticky Wilds and Scatters may be quite a challenging task, it’s likely to be worth the waiting. 

All said and done, Stellar Portals is a decent option and is undoubtedly an entertaining slot. Those not into the theme may also appreciate the developer’s effort to produce something unique since the feature set will be the main reason why players will feel drawn to spin the reels on it, so Snowborn’s creating is definitely worth a spin or two.
