    Intro to Doctor Electro

    Doctor Electro is a futuristic character that can remind one of an evil version of Albert Einstein. The slot was created by Kalamba Games in 2017 and is a great addition to their portfolio.

    Doctor Electro is a game with a lot of features and there are unlockable features within each of them. The most simple way to explain this is by first having a look at the setup of the slot.

    As you can see there are a total of 5 reels in the game and there are 4 rows. At the top of the slot you can notice that there is room for 3 more symbols in each reel. These can be unlocked and make sure you win big payouts during the features (features we’re going to talk about below).

    First up is the Hyper Bonus (this one can only be bought). Here you can choose either 25, 20, 15 or 8 free spins. During the bonus you can get what Kalamba Games call expansion symbols. These symbols will increase the size of the rows in each wheel they land on. Additionally you will get an extra spin every time an expansion symbol opens or progresses towards a new row.

    Therefore you have a bigger chance of opening up more rows (and winning more money of course) the more free spins that you choose to buy.

    Furthermore you can win standard free spins with three or more scatters. This gives you 8 free spins and 2x multiplier on all winning combinations. You can also get expansion symbols here.


    Doctor Electro is a slot machine with a lot of features. The biggest win is 2000x and it has a high RTP of 97.55%. The title was created by Kalamba Games and was released in 2019.
