Doctor Electro – Bonus Feature

In this slot, you can decide to either wait for 3 gold and silver shield to appear on the reels to play 8 Free rounds with 2x multipliers. Or if your impatient to see what the Free Spins with Expanding reels have to offer. You can buy your way into the feature by clicking on the hyper bet button.

Doing so will give you the option to play 4 different Free Spins levels. Buying the red level means that you’ll play 25 Free rounds. The purple, green, and blue will initiate 20, 15, and 8 Free Spins.

Symbols and Scatter

The battery symbol also plays a crucial role in the Free Spins feature. In fact, during the bonus, you’ll have the chance to collect 1, 2 or 3 gold and blue batteries to unlock another row on the game interface. And every time you’ll unlock a row, you’ll win extra spins too.

Two other important symbols in Doctor Electro are the Doctor Electro on an orange background and the wild. In fact, this symbol combination could award you either the gold or platinum jackpot that you’ll see on the right-hand side of the reels after loading the game.

Our thoughts on this Video slot

All and all, Doctor Electro is a well-conceptualised game. The paytable is well-balanced if you take into account the multiple betways. And the graphics and animations help to deliver a good storyline to. The Free Spins feature also offers a lot of value, in our opinion. And if your bankroll allows it, it’s worth buy-in your way into it at least at the lowest level once.

In fact, from our experience, it was very easy to win additional rounds. And perhaps we were lucky, but it sure felt that the feature kept on giving. And our test rounds at 30p per spins resulted in a whopping 826.5x win. But just because we were lucky, it doesn’t mean that you will too. So, remember to pace your bets. Doing so in combination with claiming a casino bonus may mean that you’ll have more spin time with one deposit.
