MS or also known as Scientific games hasn’t released a new big slot in a while now. They are known for their slots like Montezuma and many more. Is this the new slot we have been waiting for them to release?

The slot is based on Dr Volt’s lavatory who is a very mad scientist. The slot has a very childlike theme which doesn’t appeal to some people. It has 5 reels and 3 rows.


There are 4 jackpot prizes

* Mini-£40

* Minor-£200

* Major-£4,000

* Grand-£10,000

These prizes can be won in the Robot bonus by getting the high voltage spins which we will talk about in detail.

Robot Bonus and High voltage spins 

To achieve the robot bonus, you need to land 6 or more robot symbols in the base game to be awarded 5 free spins. 

The robot symbols that landed to get you the free spins will be locked in place. After each spin, any adjacent robot symbols to the ones you have already landed will join up and transform into a robot shape, this shape will change the more symbols you land. Any robot shape that doesn’t cover over 4 will come up as a value of around 5-20x your bet.

After these 5 spins, any robot shape that covers 4 or more spaces on reels will become a high voltage reel. The high voltage reel will spin after the robot spins and show different cash prizes or jackpot prizes while spinning. These prizes will be bigger value the bigger the robot symbol was at the end of the robot spins.  Sounds confusing but it is a very simple concept.  

This feature could pay huge but the potential of landing enough robot symbols to even get a high voltage spin seems unlikely but if you are lucky enough you could get some good profit.

Volts and Bolts free spins 

For this feature you need to land 3 or more scientist scatters in the base game. 

This awards players 12 free spins, reel 3 during these spins will only contain only scientist symbols and wilds.  

This feature can retrigger but you can also trigger the robot bonus by landing 6 or more robot symbols. I feel this bonus doesn’t have much potential.

 I really like the theme of this slot as it is very unique and the music matches it very well. The design is very childlike but it is fun to play. The free spins seem to only pay around 30-50x unless you get one big line up with wilds. The robot spins are very difficult to acquire and it is also difficult to even land a decent amount of robot symbols to get high voltage spins. The jackpots are of course just for show as it is so rare to even get a chance at them. Overall
