Play Cosmic Eclipse Slot for Free & Review

Cosmic Eclipse is a 5 reel, 10 payline slot from NetEnt that can be played from 10p a spin on all devices. This space themed title is all about the Black Hole feature where 1 symbol is randomly chosen and collected with each free re-spin. The re-spins keep on coming as long as more symbols appear – if you get 15 or more, the re-spins end but all collected symbols are added to the reels to hopefully fill the reels with the same symbol.

Cosmic Eclipse is powered by Net Entertainment and has 5 reels and 10 paylines – playable from 10p to £100 per spin, it can be played on all devices including laptops, PCs, tablets and smartphones (such as iOS and Android). This space themed offering is rather simple but comes with a Black Hole feature where you get free re-spins which guarantee winning combinations.

Visually, Cosmic Eclipse is what you’d expect – set in outer space, it has a psychedelic feel to it as the background swirls as you spin the reels. Symbols include 6 rocky planets – the orange one is the most lucrative giving you 5, 10 or 60 times your stake for 3, 4 or 5 across a payline. There is also a wild symbol which substitutes for all symbols bar the Bonus symbol.

The Bonus symbol only appears on the last reel (i.e. reel 5) – when it does, it will trigger Cosmic Eclipse’s only attraction, the Black Hole feature. 1 of the symbols present on the reels (bar the Bonus or Wild) is randomly picked and then becomes active.

The Bonus symbol then becomes the active symbol – all the active and wild symbols on the reels are then collected with free re-spins awarded. After every re-spin, all active and wild symbols are collect and removed from the reels.

When no more symbols are collected or 15 or more symbols have been collected, the re-spins come to a stop and the reels are cleared. Then all collected symbols are placed randomly on the reels – this is guaranteed to give you at least 1 winning combination.

Cosmic Eclipse is a simple slot but the Black Hole feature does trigger fairly frequently - the key is to get a high value symbol and to get them on each re-spin so you collect 15 or more. If you do this, you could end up with the screen full of the same symbol which can result in wins of up to 600 times your stake. You can win more than this as you can also get the wins from the free re-spins.

I found it to be quite similar to Starburst (also by NetEnt) which isn’t a bad thing – if you like the space theme, Playtech’s Space Invaders and NetEnt’s Space Wars are recommended.
