How to play Doctor Electro mobile slot

This crazy villain wants just one thing: to destroy the reels, one slow battery at a time. But like most evil schemes, this Doctor Electro slot falls a little flat.

Join us in the lair of this Doctor Electro mobile slot where you’ll be greeted by 5 reels that are 7 rows high. Only you start playing with only 4 rows unlocked and 1024 ways, all for a minimum bet of 0.30 a spin.

So far, not too bad. This villain seems to be a strange combination between Norman Oswald and Doc Ock and generally fits the theme of the mad scientist well enough that comic book slot fans will nod at the homage to some of the greatest villains in Marvel.

Even the sounds and animations are good enough, though you may want to put your own music on after a while if you get bored of the little ‘ah ah!’ coming from the villain every 2 seconds.

The Doctor Electro slot asks you to become his lab assistant

Which is a lot less glamorous than you might think. Or it’s exactly as glamorous as you think, as you spin 5 reels collecting battery symbols.

Really, that’s about 90% of the point of this game. Collect enough of them, and when you find three of these in one spin, you get 5 free spins with the reels expanded by either 5 or 7 rows of symbols.

Or, catch 3 scatters to trigger 8 free spins, where the battery expands the reels straight away and gives you a +1 spin. You need to collect 7 symbols per reel to open up a huge multi-pay slot.

Much like any Lab Assistant, you don’t get paid a lot

What is it with Mad Scientist slots failing to hit the mark? From the Reel Attraction slot to the Volts and Bolts slot, they never quite live up to expectations.

And the problem with this Doctor Electro online slot is that you really need a screen full of Dr Electro symbols to get anything decent. It’s the highest paying symbol, and it’s also how you win one of two in-game jackpots.

You are spending a lot of time collecting batteries, but you rarely get to see the results of these experiments – meaning that both of the free spin bonuses are hard to trigger.

It may lead you to buy the bonus, much like you can in the Megaways Fishing Frenzy slot, but don’t expect to win much more than the buying price.

There are nuggets of glory here, but Doctor Electro does not share his inventiveness very easily.

Bonus Features

Wilds: The ball of yellow energy is the wild symbol and can be used to substitute for all other symbols except bonus and expansion symbols.

Hyperspins: Every Expansion symbol (the battery) lights up the top 4 rows of symbols. If you catch 3 expansion symbols at any one time you start 5 free spins.

However, all the top row of symbols that have been fully charged by the batteries are removed for those 5 spins, giving you more ways to win automatically. How many expansion symbols you collected on that reel determines the height of the reel:

• 1-2 expansion symbols collected: column is 5 symbols high
• 3-6 expansion symbols collected: column is 6 symbols high
• 7+ expansion symbols collected: column is 7 symbols high

The number of expansion symbols you collect is saved between gambling slot sessions, so you can return and play at a later date to the same casino.

HyperBonus and Free Spins: The golden disc bonus symbols are the scatter and 3 on reels 1, 2 and 3 triggers 8 free spins.

You also collect expansion symbols during these bonus games, except that every one you find gives you a +1 free spin and for every 1, 3 and 7 expansion symbols collected, you increase the column for that reel.

Bonus Jackpot: There's a 2 level bonus jackpot, based on your bets alone. These are saved between session for a single player, and no one else will see your bonus jackpot amount. Think of it as your own personal progressive jackpot pot.

• Platinum Jackpot: Seeds at 1,000 times your bet. It is triggered by finding 14 or more wilds and Dr Electro symbols in a single spin.
• Gold Jackpot: Seeds at 100x your bet. It is triggered by finding any combination of 12 or more wild and Doctor Electro symbols in a single spin.

0.75% of your total bet contributes towards the two jackpots.

Buy the Hyper Bonus: You can choose to buy the free spin bonus round and trigger this whenever you want. the RTP of the game also increases.

• 8 free spins (97.23%): 42 times your bet
• 15 free spins (97.36%): 100 times your bet
• 20 free spins (97.42%): 154 times your bet
• 25 free spins (97.55): 214 times your bet

Doctor Electro Review Conclusion

Doctor Electros is a 5 reel 4 row 1024 ways to win video slot with two free spin bonus features, wilds, and expanding reels that increase your ways to win during the bonuses. You also have two in-game jackpots.

With so much going on, you'd think this would be a little more exciting, but in truth you are just waiting to collect battery packs on each reel, trying to unlock one of two free spin rounds.

We didn't even notice this came with two mini-jackpots that are progressively getting bigger just for you, the player, but there they are.

That's how it feels with this Doctor Electro slot on mobile; you feel like the game is slowly bidding its time in the background doing interesting things, but with nothing much happening up front.

However, every once in a while, this Mad Scientist can surprise you, especially if you unlock enough reels and ways to win. However, part of us longs for the simplicity of the Manic Millions slot, where the crazy science exploded in your face rather than slowly fizzle in and out of excitement.
