The Stellar Portals slot has 4 different free spins bonuses you can catch and two types of wilds – this is one strange but wonderful cosmos.
Created by Snoborn exclusively for Microgaming, we weren’t sure what to expect from this Stellar Portals mobile slot, but what a wonderful surprise.
The background moves softly around making you feel like you are floating in the darkness of space, with just a slick of oil in the horizon.
There are 4 high paying symbols that look like stars in different states of going nova in red, yellow, green and purple, and finally low paying particles of different colours. It’s a pretty slot game theme that at least that bring into play any suits or card symbols.
There are two wild symbols in the base game. You’ve got the wild that just shows up and replaces every other symbol on the reels, and then you have the sticky wilds that give you re-spins.
The re-spins continue for as long as you keep getting sticky wilds on the screen. And you know what? So many casino game providers would have left it to that and given you nothing else.
But not Snowborn and not this Stellar Portals slot. Instead, you have 4 different bonus symbols that can trigger 4 different bonus free spins, each with their own different characteristics.
Depending on which of the bonus symbols you catch on screen, you may get:
All are good, but the multipliers are better – we’ve calculated the best win you can get as being 15,000x your bet. That’s competing with real money slot games such as The Grand Galore slot or even the Blinged review.
The problem, of course, is that as you don’t get to choose and these are random, you are more likely to catch sticky wilds or stacked wilds, but you know what? We’ve had some decent wins here that kept us playing, if not cashing out.
The point is that this Stellar Portals slot was fun to play, with lots of variety of feature that kept triggering, and plenty of hope for those chasing big wins.

Rising Multiplier Bonus: Land 3 rising multiplier bonus symbols to trigger this feature. It only appears on symbol 1, 3 and 4. You'll then get 6 free spins with a multiplier that increases with each spin. The multipliers are 2x, 3x, 4x, 5x, 8x, and 10x.
Stacked Wild Bonus: Land 3 stacked wild bonus symbols to trigger this feature. This appears on reels 1, 3 and 5. You'll get 6 to 9 free spins during which all reels features Stacked Wilds on the reels.
Sticky Wild Bonus: Land 3 Sticky Wild Bonus symbol to get this bonus. These symbol land on reels 1, 3 and 5 only. This Stellar Portals Bonus awards you 6 free spins with sticky wilds landing on the reel and staying sticky for the duration of the bonus.
We had great fun playing on this Stellar Portals slot game, thanks to lots of different features, a great top win, and a wide betting range.
Snowborn studio, via Microgaming slots, have created something really compelling mostly because you get a lot of chances at catching big wins, even without the multipliers.
Granted, it can be a little frustrating that you don't get the 'good' bonuses very often, but you get a bonus often enough that you don't mind too much.
All in all, if you do come across this little mobile gem, it's well worth a spin or two.
