Our reviewers can tell that WMS had a blast creating the Volts and Bolts online slot. While the game is loading, you’ll enjoy a humorous clip of Dr Volt attempting to animate the robot. We won’t spoil it for you—discover how he accomplishes this task by playing the game on a desktop computer or mobile device.

Once the reels appear on the screen, you’ll notice various amusing items scattered around the cluttered laboratory. Symbols are placed on old wooden shelves, with bubbling chemicals in the background and an octopus wriggling around as part of a bizarre experiment.

Accompanied by a chilling soundtrack, the sounds of Dr Volt’s maniacal laughter can be heard in classic mad scientist fashion when you achieve a winning combination. It’s time to open the lab door and explore the treasures that lie within.

A Laboratory Full of Surprises

You can try out the free Volts and Bolts video slots here or play for real money starting from just 0.50 per spin. The paytable discloses the value of each symbol combination, with items like a notebook, voltmeter, a bright pink brain, and a rusty wrench offering bigger prizes when they appear.

The top symbol is the game logo, which pays out a small prize for landing just two logos or 250x for a full line. The rectangular battery serves as the wild symbol, substituting for other symbols to complete additional winning combos. It can only be seen on the three middle reels and does not offer payouts on its own or substitute for Dr Volt or the robot.

The Dr Will See You Now

The diabolical Dr Volt, with his gloved hands and laughter over his latest creation, acts as the scatter symbol. Landing the Dr on three or more positions simultaneously rewards you with an instant multiplier prize and triggers a free spins bonus round. The multiplier varies based on the number of scatters, with three scatters paying twice the total bet, four scatters awarding 15x, and five or more scatters offering 100x the stake.

You receive twelve free spins, during which only Dr Volt or the wild symbol appears on the middle reel. The bonus round can be retriggered by landing three or more Dr Volt symbols, adding another 12 spins to the current round.

Claim Your Robot Rewards

If six or more robot symbols appear, the Robot Bonus spins are activated, awarding five free games. Symbols initiating the feature remain locked in place, with additional robots also locking in place and combining to fill the reels with giant robots. These giant robots offer multiplier prizes, with two robots paying twice the stake and three providing a fivefold payout.

Jackpots can be won by creating a giant robot symbol with four or more robots, awarding bet multipliers or Mini, Minor, Major, or Grand jackpot prizes. Achieving the Grand jackpot, worth 5,000x the stake, requires filling all 15 reel positions with robots. Alternatively, you could win a multiplier of up to 750x. The bonus round concludes after five spins or when all reel spots are occupied by androids.
