The design here is very well done - Dr Volts’ laboratory is the setting. On the reels you’ll see A to J playing cards as well as a diary, a wrench, a voltmeter and a brain. The best of the standard symbols is the Volts and Bolts logo which pays 5 times stake if you land 5 across a payline.
The battery is the wild which replaces all other symbols apart from the scatter and robot symbols. Volts and Bolts comes with 3 bonus features.
Robot Lock It Link feature - this round is triggered by landing 6 or more robot bonus symbols on the same spin. You’ll then be awarded 5 free spins. Every time a robot lands, it locks in place. These can combine and transform into larger robot shapes.
When 4 or more positions are covered with robots, they’ll transform into an Electricity Reel. This triggers the High Voltage Spins feature where spins could deliver payouts of between 100 and 750 times your total stake as well as 1 of the Mini, Minor, Major or Grand jackpot. The more robots in the combination, the bigger the potential awards.
Mad Scientist Free Spins feature - land 3, 4 or 5 scatters on the same spin and you’ll receive a payout of 2, 15 or 100 times your total stake as well as 12 free spins.
Volts and Bolts is one of WMS’ better slot games. The visuals are excellent and the combination of features on offer here is a good one. The number of free spins awarded in the Robot Lock It Link feature is only small but if you land a good combination of sticky robots, the High Voltage spins can cook up some crackling action. If you like the theme, Manic Millions by NextGen Gaming is worth looking into.
