See All

A series called Power Spins is the one where you will find Nuclear 9s, and along with Atomic 8s and Sonic 7s, it’s going to come from Microgaming. The game offers a similar style of design and layout to the other two slots, but it has its own advantages, such as the Rolling Reels feature which is part of the Power Spin option, the one you pay extra for. The game’s theme appears to be nuclear inspired, and the graphics show it. You have a wild, a scatter, multipliers and Rolling Reels in the way of features. The slot offers the same 5 reels / 9 lines as the other games from the series, while the payout goes to $50,000.

Betting and Prizes

The wagering system seems to be the same in all the games from this series, covering 9 lines and with up to 10 coins of $1 for each one. You can spend as little as $0.01 if you want to, but there is that option to go up to $90 as well.

Since the top prize can get to a maximum of $50,000, the reward would be at 5,000x the line bet, which is an OK value, but not high.

Nuclear 9's Slot Features

First of all, let’s take a look at what we get from the Power Spin option. This option requires you to use an extra bet, which takes the maximum wager from $90 to $120, so it’s the equivalent of three additional lines. It will bring you a feature called Rolling Reels, which will get rid of symbols that are part of winning combinations, and will bring new ones to your screen, which will form their own payouts hopefully. There are even multipliers which can appear thanks to this feature, once you’ve had a couple of consecutive wins through it.

The Nuclear Logo is the wild symbol and you will get to use it as a replacement for the usual regular symbols, and not for the scatters. It gets better, as the presence of the wild multiple times on the same line will get you a special kind of combo, which can pay the slot’s jackpot.

The second feature icon gets you the scatter, with the nuclear atom and a logo in front, a symbol which can reward you by being present enough times during the same spin, no matter the exact location of those symbols. Payouts seem to go up to 300x the bet.

Theme & Design

The nuclear theme that was picked for this Power Spins Microgaming online slot means that you’re going to get a couple of logos that are related to this field, along with symbols with 9s colored in green, yellow and pink, Bar symbols, cherries and a golden bell.


I enjoyed the Rolling Reels feature that Nuclear 9s has for the player, and overall it is a decent game to play from the Power Spins collection.
