Diamond Supernova 20 Slot Machine Review

Diamond Supernova 20, a slot with fairly simple gameplay, comes as part of a bigger series, of which it is the representative with 20 active lines (5, 40, or 100 lines are offered in the others). It will be released by Push Gaming.

You get 5x3 reels, and there will be 20 win lines active for that standard setup. A slot where low volatility is to be expected, it has a decent top prize of 1,016x the stake, while its RTP gets up to 96.33%. There aren’t that many features for you to check out, only scatters and the Diamonds that can lead to the bigger wins.

Betting and Prizes

The standard betting range you can use in Diamond Supernova 20 starts from the $0.10 minimum, and it goes up to $100 if the players want to spend more.

In terms of rewards, it’s going to pay at most 1,016x the stake, like the other slots of this series. Very Low volatility is there to make that prize look good, but I would still recommend you go with the version set to a 96.33% RTP.

Diamond Supernova 20 Game Features

Diamond Supernova 20 belongs to a category of simpler slots, one where the list of special features is intentionally kept as short as possible. As such, you don’t get the usual mechanics that have become part of the majority of today’s games. There are no wild symbols to help you form new combinations, no free spins, or respins that have become so popular lately.

What you’re left with is the option to form combinations of 3 to 5 symbols. As an alternative, getting 3 scatters to land can also bring you a reward, even going up to the top jackpot of this slot.

The scatter symbols that can get you paid will come in three variants, colored blue, red, or golden, and showing Stars. These symbols can only land on the 1st, 3rd, and 5th reels. You will need three scatter symbols to get paid. It can be a smaller reward, just 5x the stake, if it’s a mixed combination of Stars. If the Star scatters are of the same type, they pay 25x (Blue Stars), 100x (Red Stars), or 1,000x the stake (Golden Stars).

Theme & Design

The graphics of the Diamond Supernova 20 demo are just as simple as the mechanics involved. There are three types of Stars you get to use as scatters, plus the regular symbols with Triple Diamonds, Double Diamonds, Single Diamond, Red Seven, Golden Bell, Ace, King, Queen, and Jack.

Conclusion

Diamond Supernova 20 is only one option in a series, and if you want the version with 20 active lines, go for it. It’s simple, with no major features, but the ones included manage to pay the top prize if the conditions are met.
