Volts and bolts online slot

Volts and Bolts by WMS is an electrifying slot game that takes players into the quirky laboratory of a mad scientist. With a theme centered around inventions and electricity, this slot combines a unique narrative with the thrill of potential big wins.

The Volts and Bolts slot is produced by WMS and opens with a very fun animated introduction that introduces the theme and atmosphere of the game. A slightly crazy scientist, with a little trick manages to activate his new creation: a robot.

From here the adventure of the two protagonists begins. The robot still doesn’t want to know if it’s working properly, while the scientist tries to give it electric shocks. Every time he succeeds, the player wins nice prizes, with grouped symbols that help create winning combinations.

Slot machine graphics

From an aesthetic point of view, the Volts and Bolts slot is really pleasing. The symbols are all in 3D and feature high-quality graphics.

Among the game symbols we find all the scientist’s work tools, including his diary, the ammeter, the wrench, a battery and even a human brain. From here, we understand that perhaps the scientist placed a human brain in the robot. Maybe he has seen Pinocchio too many times?

The symbols also include the scientist himself and the robot. The latter can appear only with his head (1 symbol), in full (2 symbols), in full with his arms open (4 symbols). Every time he appears, a very funny animation is created in the boxes with the sly robot being awakened by new energy.

Slot features and bonuses

The structure of the Volts and Bolts slot is presented in the typical 5×3 format, i.e. with 5 reels and 3 lines. The paylines, i.e. the payment lines, instead reach 50. Therefore, on each spin the same symbols can reward based on 50 different alignment methods.

There are 3 special symbols:

  • Battery (wild or wild symbol): can appear on reels 2, 3, 4 and 5 and replace any other symbol on the slot, except robots and scientist
  • Scientist (scatter symbol): if he appears in 3 or more boxes, he activates free spins
  • Robot (scatter symbol): if 6 or more boxes appear, activate the Robot Bonus function

The features therefore include free spins and a bonus game.

Obtaining 3 or more Scientist symbols activates 12 free spins during which only Scientist and wild symbols appear on the central reel. Free spins can be retriggered if another 3 or more Scientist symbols reappear on the same spin during the free spins.

Displaying 6 or more Robot symbols activates 5 Robot Bonus spins. During these spins, the robots remain stationary in their position while the other symbols change based on what happens on the spinning reels. If other robot symbols appear, they will remain attached until the end of the free spins. Ultimately, all robot symbols on the screen offer a prize.

If you fill the screen with robots, you basically win 750 times your activation stake. Furthermore, there are 4 jackpots available ranging from 20x to 5000x the stake.
