Bonus Features

Sticky wilds / respins

Whenever a sticky wild symbol lands on the reels, you will get a respin where the wild will remain locked in place. If any sticky wilds land during the respin, the process will repeat.

Bonus symbols

Four different bonus symbols can land on reels 1, 3, and 5. Landing 3 matching bonus symbols will activate a specific bonus game.

The Sticky Wild bonus gives you 6 free spins and any sticky wilds that land on the reels will remain locked in place for all the free spins. The Stacked Wild bonus gives you 6 to 9 free spins and all reels will feature stacked wilds. The Rising Multiplier bonus gives you 6 free spins and a multiplier trail that goes from 2x to 10x. The Multiplier bonus gives you 6 to 9 free spins and a 5x multiplier.

Our Verdict

Stella Portals slot takes a unique swing at the space-themed slot genre and the result is more hit than miss. The slot takes a somewhat safe and familiar approach to its theme; however, the graphics, animations, and soundtrack are well-executed, creating a spacey, mysterious atmosphere. Gameplay mostly centers around grabbing wins from sticky wilds and respins, with plenty of low and mid-level prizes coming your way as you spin. Having a quartet of scatter-activated bonus features is an exciting prospect and attempting to activate all four of them can become a temporary obsession.

The slot would benefit from further development of the theme as it is currently limited to just aesthetics, with no story or narrative to grab the attention. This is a competent title that rewards you enough to keep you going for the big wins, but the entertainment value may fall short for some players.
