Volts and Bolts Slot Machine

Do you dare to enter the laboratory of Dr Volt, where glowing chemicals and strange pieces of equipment zap life into disembodied brains? Join us while we enter Dr Volt’s lab for a detailed review of Volts and Bolts online slot.

This five-reel, 50-payline slot machine has a mad scientist constructing his latest invention and where you can claim wins of up to 750x your stake. The Volts and Bolts video slot comes from Williams Interactive, (WMS) and has some fun CGI animations, with 3D-effect graphics to bring Dr Volt and his creations to life. Features include wild substitutions, free spins and a unique Robot Bonus round that can fill the reels with a golden android.

It’s clear to our reviewers that WMS have really had some fun developing Volts and Bolts online slot. As it’s loading up, you get treated to a hilarious clip of Dr Volt trying to bring the robot to life, but we won’t spoil it for you and you can see for yourself how he manages this task when you open up the game on a desktop PC or mobile device.

Once the reels are on screen, you can see even more fun items strewn around this untidy laboratory. The symbols are set across old wooden shelves, while chemicals bubble away in the background and an octopus wriggles around as it becomes part of some bizarre experiment.

Alongside the chilling soundtrack, Dr Volt can be heard laughing in a classic mad scientist style when you land a winning combination. It’s time to open the door to the lab now and check out the rewards that can be found within.

A Laboratory Full of Surprises

You can experiment on free Volts and Bolts video slots right here or play for real cash from just 0.50 per spin. The paytable reveals what each symbol combination is worth when you land three or more of the same type across any of the 50 paylines from left to right, with playing card icons returning the smaller prizes.

Some of the items that Dr Volt uses in his workshop, such as a notebook, voltmeter, a bright pink brain and a rusty wrench will be worth bigger prizes when they appear.

The top symbol is the game logo and unlike others, which need to land on at least three reels, just two logos will be worth a small prize of twice the per line stake, while full lines will pay out 250x.

A rectangular battery is the wild symbol, charging up your bankroll by substituting for other symbols and completing extra winning combinations. It’s only seen on the middle three reels, so isn’t worth anything on its own and can’t substitute for Dr Volt or the robot.

The Dr Will See You Now

The maniacal Dr Volt, wringing his gloved hands and laughing about his latest creation, is a scatter symbol. Any time you land the Dr in three or more places at once, you win an instant multiplier prize and then a free spins bonus round is triggered. The multiplier depends on how many scatters appeared, with three scatters paying out twice the total bet, while four scatters are worth 15x and any five or more will pay 100x the stake.

Twelve free spins are awarded, during which only Dr Volt or the wild symbol will be on the middle reel. The bonus round can be retriggered by three or more Dr Volt symbols and another 12 spins are added to the end of the current round.

Claim Your Robot Rewards

Any time six or more robot symbols are seen, the Robot Bonus spins are triggered, with five free games, during which any symbols that started the feature stay locked in place. If more robots appear, these also lock in place, with any adjacent ones joining together to fill the reels with giant robots. These pay multiplier prizes, with any two robots worth twice the stake and three together will pay out five times.

Jackpots can be won when four or more robots create a giant robot symbol and you win either bet multipliers, or the Mini, Minor, Major, or Grand jackpot prizes. The Grand jackpot, that’s worth 5,000x the stake, can be claimed when all 15 positions on the reels are filled with robots, although you could also win a multiplier of up to 750x instead. The bonus round ends after five spins or when all spots on the reels are filled with an army of androids.

Charging up This Game

With just 0.50 needed to spin for real cash awards, Volts and Bolts slot should be within the reach of all players. The maximum wager is 50.00 per spin which should be plenty for most of us except real high rollers. Other control options include an Auto function, though there’s no fast-spin mode available.

This game is fully mobile optimized and looks great on iPhones, iPads and Windows devices, plus of course, the android can fill the screen on Android-powered mobile phones and tablets.

Reviewing Other Robotic Reels

The Robo Jack video slot from Microgaming is another game where robots fill the reels. There are 243 ways to win running across the game and this mechanical marvel comes packed full of features. Five robots can help you out in the free spins bonus games, enhancing the reels with wild reels, extra spins and win multipliers. Take the action up a gear with this fun slot that’s found at Microgaming-powered online and mobile casino sites.

Our Verdict: Is This a Scientific Breakthrough?

Our review team thought Volts and Bolts was certainly a good-looking slot machine, with the animations developed to a very high standard and a fun soundtrack to go with it all. It’s got a high return to players percentage and like all WMS games, it’s been independently certified for fair play and reliability.

If you have ever played WMS slot machines such as Invaders From the Planet Moolah, or Alice and the Mad Tea Party, you will already know that this Illinois-based developer likes to add some humor to many of their games.

They’ve succeeded here, giving us an online slot machine that can make you grin as the reels spin, while hopefully helping you to laugh all the way to the bank when some of the features are triggered. The Robot Bonus is particularly valuable, even if you don’t win a jackpot.

Get ready to enter the lab of Dr Volt and start spinning up some high-voltage winnings.
