There’s a slightly anarchic feel to the design or Doctor Electro. Set against a laboratory backdrop, you’ll see A to 9 royals as well as an assortment of technicians, aliens and little green men. The Doc himself is the best paying standard symbol, awarding 3.33 times your stake if you land 5 in combination. There’s also a wild that substitutes for all of the standard symbols. There are couple of innovative bonus features on offer in Doctor Electro.

Look out for the expansion symbols. Whenever these hit, they illuminate a meter that cover the top 3 positions on that reel. These meters are made up of 1, 2 or 4 positions and come into their own when you trigger the Hyper Spins feature.

To do that, you’ll need to land 3 expansion symbols on the same spin. You’ll then play 5 Hyper Spins. Any meter position that was filled in the base game then unlocks and becomes active in this feature. This increases the number of ways to win too. Collecting expansion symbols during the Hyper Spins can open up more positions here too. If all the columns reach their maximum height, you’ll be playing on reels that offer 16,807 ways to win.

Free Spins feature – land 3 Bonus Scatters and you’ll win a payout of double your stake as well as 8 free spins. Collecting expansion symbols opens up more symbol positions here as well as adding more free spins to your total. If you don’t want to wait to trigger the Free Spins feature, you can pay to activate the Hyper Bonus feature. You’ll then be offered 8, 15, 20 or 25 free spins.

Finally, there’s the Bonus Jackpots feature – Doctor Electro offers a chance to land 1 of 2 jackpot prizes. These are triggered by landing a combination of wild and Dr Electro symbols on the same spin. Land 12 to trigger the Gold Jackpot of 100 times your stake. 14 triggers the Platinum Jackpot worth at least 1,000 times your stake.

Doctor Electro is a quite an unusual slot. The game engine is similar to a MegaWays slot and can deliver to decent potential when you manage to land the bonus features and increase the potential ways to win. There’s a madcap feel to the design which fits the mad scientist theme rather well.

We wouldn’t be wanting a consultation with Dr Electro but, as a host to a potentially explosive slot, he does the job pretty well. It’s also high variance and can give you payouts of up to 2,000 times your stake on each spin or free spin. There’s also the 2 progressive jackpots of course. If you like the theme, NextGen Gaming’s Manic Millions is recommended.
