Doctor Electro slot is a new release from Kalamba Games that offers some big payouts and lots of ways to win depending on how the Bonuses play out. It has a pretty electrifying design, with the doctor himself standing by the reels and his colleagues appearing as some of the many symbols in the game. Initially, there are just 5 reels with 4 rows, but when the Free Spins Bonuses play out, this can increase with the collection of special symbols, but I’ll come onto that in more detail shortly. The main thing you need to do is spin the reels to get a winning combination from left to right using the base symbols. These are as follows, ranked in ascending order based on their value:

  • 9, 10, Jack, Queen, King or Ace (lowest value)
  • Robot or Chimp
  • Young Scientist or Alien
  • Doctor Electro (highest value)

There are Wild symbols too which substitute for all other symbols in a winning combination apart from the Bonus symbol and the Expansion symbol.

Doctor Electro Slot Bonuses and Features

Free Spins Bonus. There are Scatter symbols in this game shown as Bonus symbols which, when you collect 3 of them at the same time, will award you with some free spins. You’ll get 8 of these in total while also getting 2x your total bet as a reward. You’ll want to collect expansion symbols during the Bonus, expanding columns and getting you more free spins and expanding the columns, giving you more ways to win.

Hyper Bonus. At the bottom right hand side of the screen you’ll see an option to buy some hyper spins. You can then select a number of free spins to collect and play the Bonus immediately. Once again, you’ll want to collect expansion symbols for each column to win more free spins and increase the column height for more ways to win.

Bonus Jackpots. Doctor Electro slot also has some Jackpots you can win. These are awarded for a combination of Wild and Doctor Electro symbols so that the total number of symbols is either 12, giving you the Gold Level Bonus Jackpot, or 14, giving you the Platinum Level Bonus Jackpot. You can see these figures on the side of the screen so you know what’s available.

doctor electro slot rules


Doctor Electro slot is a new game from Kalamba Games which is largely focused on giving you lots of free spins and the opportunities for unlocking more ways to win. You do this by collecting the special expansion symbols which unlock an extra position and give you free spins. In total, there are up to 16807 ways to win when you unlock all positions. You can also buy the Bonus, although it works a bit differently when you do this. To top it all off, there are a couple of jackpots that you can win using the Wild and Doctor Electro symbols, the most valuable symbols in the game. Depending on how many you have, your payout will be bigger. It’s quite an interesting slot and works differently to most, although all of the features here are based on the popular ones from most slots like free spins and jackpots. It’s quite high variance and can offer some big payouts, but I’m just not sure it all works together. I do like that it’s a bit different, but you’ll have to decide for yourself whether it’s any good for you. You can do this using the link below, and also check out some of their other slots here.
