Theme

Explore the most hard-to-reach places of the open space together with the Cosmic Eclipse slot. If you are lucky enough, you’ll reach the most mysterious part of the universe, a black hole! Like every other NetEnt slot, Cosmic Eclipse will impress you with its graphics, animations, and sounds. Effects like glowing, sparkling, and splashing are all over the place. And, of course, you’ll hear a mysterious soundtrack that makes your trip even more intriguing.

A symbols’ collection of Cosmic Eclipse contains only 8 elements. Let’s start with the regular symbols and their respective payouts:

  • Diamonds meteor: 0.5x, 1x, 3x
  • Spades meteor: 0.5x, 1.5x, 4x
  • Crystal meteor: 0.5x, 2x, 5x
  • Green planet: 2x, 4x, 15x
  • Yellow planet: 3x, 6x, 35x
  • Red planet: 5x, 10x, 60x

The slot has a Wild symbol that substitutes regular-pay elements. Another special element is a Black Hole. It can land only the 5th reel, activating bonus respins.

About NetEnt

NetEnt is one of the pioneers of online gambling. A Swedish developer is considered 1 of the 3 biggest iGaming companies in the world. NetEnt is famous for its innovative approach, exclusive design, and calibrated math models.

The company’s history started in the 1960s when it was called Cherry A/B. From the 1960s to the mid-1990s, the provider produced slot machines for land-based casinos. Finally, in 1996 NetEnt debuted in the online segment and became one of the pioneers of online gambling.

It can take hours if we start to count achievements, awards, and innovations from NetEnt. The company released numerous epic slots. Here are some examples of the provider’s most popular games – Dead or Alive, Starburst, Gonzo’s Quest, Divine Fortune, Serengeti Kings, etc. Also, the provider has a big portfolio of branded games – from Narcos to Conan.

NetEnt is not only about developing games. The company also offers back-office services, marketing tools, and other B2B and B2C solutions. The price of its acquisition is a good indication of the provider’s place in online gambling. In late 2020 Evolution paid more than 2 billion euros to acquire NetEnt in one of the biggest deals in the history of the iGaming industry.

Bonus Rounds & Free Spins

7 

Bonus Respins

Land a Black Hole symbol on the 5th reel to activate Bonus Respins. After the start of Respins, a random active symbol from regulars will be chosen, and the Black Hole will be transformed into that symbol.

The main idea behind the Bonus Respins is landing active and wild symbols. The round will last as long as you land either active or Wild symbols or collect 15 Active + Wild symbols. Once you are out of respins, all collected elements will be transferred to the board to create the best possible winning line.

Max Win

6 
The maximum win in the Cosmic Eclipse is 600x the bet.

Cosmic Eclipse is not your pick if you want to get a massive win. The highest possible winning odds in the slot is 600x, and you have to fill the entire board with the highest-pay element to reach the max win.

Bonus Respins are more attractive than base spins when it comes to big payouts. And there is even a decent chance to get 15 symbols of a kind during the bonus game. Who knows, maybe you’ll be the one who collects the 15 highest-pay elements for a 600x win.

Overall Rating

7.3
Cosmic Eclipse captivates players with its design and simplicity. The slot doesn’t offer big payouts or incredible features, but it still attracts players. We think it’s a great game if you want to relax and enjoy rolling without many distractions. Also, the slot holds the balance quite well.
