Cosmic Eclipse

By Matthew Kennedy | Updated 28 May 2026

At this point, we expect huge things from every NetEnt slot, and we also have a list of criteria that we expect to see matched.Firstly, we expect a complicated slot, with an engaging and immersive narrative, and unique bonus rounds. Cosmic Eclipse is something of an anomaly in terms of recent NetEnt releases, because its bonus round is certainly unique, but it actively avoids the other two factors.

About the slot

This is the simplest slot NetEnt have released in some time, but that doesn’t change the fact that it looks stunning.With a space theme (obviously) there is a black hole to the side of the reels, which we will get into later.With only six standard symbols (three planets for the high values and three asteroids for the lower values) wins can be pretty frequent, and everything stays on theme.If you prefer complexity in your games, this slot may be a disappointment for you, but if you are someone who likes relaxed and peaceful slot play, then this is the best option we’ve seen in a while.

Gameplay

Land the black hole bonus symbol on reel five to enter the intriguing bonus round.One symbol that is in view will now be sucked towards the black hole, you will then receive respins until that symbol covers all positions surrounding the black hole, or no more of that symbol land.Once the bonus round is over, the symbols will be fired back onto the reels, creating a guaranteed win that can be a decent one if you’re lucky.Even when they go basic, NetEnt don’t go basic, and Cosmic Eclipse is proof that even when the Swedish software developer is working with a simple concept, they’ll still give you a bonus round that you’ve never seen before!
