Volts and Bolts Slot RTP, Symbols & Payouts
As mentioned above, the Volts and Bolts slot RTP is 95.63%. This is a standard average payout percentage for an online slot in the US. Still, we recommend picking games based on how fun you find them. RTP values will not be indicative of your personal gameplay experience. In any case, its medium volatility will be useful if you’re wagering any online casino sign up bonuses.
The game comes with multiple symbols: the Volts and Bolts logo, the brain, the voltmeter and the wrench, and the scientific manual. The Logo is by far the best-paying, offering 250x for 5x on a line. The low-paying symbols are made up of high cards, but they’re mostly filler.

With bets between 50 cents and $50 per spin, players do have a fair amount of flexibility when playing, even despite the fixed paylines. The four jackpots available also sweeten the deal when you play Volts and Bolts slot.
Three specials symbols can be found here, though none of them have their own paytables. The Wild spins on the middle reels and will substitute any of the basic symbols. There are two Scatters – the Scientist Scatter and the Robot Scatter. Spin enough of each, and you’ll trigger a bonus round.
All Bonus Features – Free Spins and Robot Bonus Spins
There are several interesting Volts and Bolts bonus features to go over. Firstly, our mad scientist triggers 12 free spins when he appears on exactly three of the reels. If you spin more than three, you’ll earn x15 or x100 the bet amount, depending on how many symbols are involved. During the free spins, the middle reel will be covered only by scientist and wild symbols.
Volts and Bolts also has a dedicated bonus game, known as the Robot Bonus Spins. If you are familiar with Light and Wonder’s Ultimate Fire Link China Street slot, this bonus works almost exactly like the Fire Link round.
Essentially, instead of Fire Link symbols, you can land robot symbols on the reels. If you land six in one spin, these lock into place and activate the feature. They will stay in place during a total of five free spins while you gather more robots. Once the Robot Bonus Spins are over, you will receive the value of each of the robot symbols.
The bigger a “block” of robot symbols you have, the higher your takeaway will be in the form of a multiplier on your original bet. If you get big enough blocks, you can finally take home one of the game’s four jackpots. This unique feature is one of the primary reasons why gamblers play Volts and Bolts online.
