Game Symbols

The Stellar Portals slot (Star portal) is completely devoted to the space theme. The futuristic style of the machine is perfectly emphasized by the symbols - mysterious sparkling spots, similar to mysterious cosmic nebulae, black holes, portals, multicoloured stars. In general, a smartly developed concept, except that there are not enough aliens – although who knows exactly where these portals lead!

Bonus Rounds & Free Spins

The slot pleases players with a colossal number of special symbols. In addition to the usual wild and scatter, the slot features Sticky Wilds, Multiplayer Bonus, Respin Multiplayer Bonus, Stacked Wild Bonus, and Sticky Wilds Bonus – each of which has interesting functions of the same name.

The Sticky Wilds feature is activated after the symbol appears on at least one of the Sticky Wilds reels. The player is given a respin, during which there is a high probability of another Sticky Wilds falling out of the value that brings the second respin, and both wilds are fixed on the playing field.

A combination of three Multiplayer Bonus symbols triggers 6 or 9 free spins. A multiplier of 5x is applied to all wins.

If three Resing Multiplayer Bonus symbols coincide on the reels, the player will be given the opportunity to spend six free spins, during which the multiplier will increase from 2x right up to 10x.

The Stacked Wild Bonus feature is activated if the corresponding symbols appear on the first, third, and fifth reels. The player is given from six to nine spins, plus the likelihood of difficult wild symbols appearing increases.

The Sticky Wilds Bonus feature brings the player six spins, and all the drawn Sticky Wilds Bonus symbols automatically become fixed until the end of the free spins.

Overall Rating

8.2

In general, Stellar Portals is just a godsend for those who are tired of banal slot machines with a typical set of functions. It may be difficult for beginners at first to get used to such a variety of bonuses – on the other hand, where else can you get so many chances to hit a solid jackpot?
