Theme and Design

Thunderbolt is an electrifying online slot that takes players on a thrilling ride through the world of electricity. The game’s theme revolves around bolts of lightning, which is evident from its name and design. As soon as you launch the game, you’ll be greeted by a dramatic backdrop featuring a dark sky with thunderstorms brewing in the distance. The reels are set against this ominous background, creating an immersive atmosphere that sets the tone for the game.

The symbols in Thunderbolt are also closely related to electricity and storms. These include lightning bolts, electrical charges, clouds, and even Thor’s hammer, Mjolnir. Each symbol is uniquely designed to fit into the electrifying theme, making it visually appealing to play. The overall design of the slot is sleek and modern, with clean lines and minimal distractions, allowing players to focus on the gameplay.

Symbols

The Thunderbolt slot features a mix of low-paying symbols, including card values from 9-Ace, as well as high-paying ones like Thor’s hammer (Mjolnir) and Lightning Bolt. The game also has two special symbols: Wild and Scatter. These are key elements in unlocking the slot’s various bonus features.

The Low-Paying Symbols:

  • Card Values (9-Ace)

These card values pay out in a standard manner, with each symbol paying according to its respective value.

  • Card Value 10 pays 1x
  • Jack Pays 2x
  • Queen Pays 3x
  • King Pays 4x

The High-Paying Symbols:

  • Mjolnir (Thor’s Hammer) Paying out up to 100 times the total bet.
  • Lightning Bolt symbol, which can pay as high as 2000 coins in a combination.

Wilds

In Thunderbolt, Wild is represented by Thor himself. He is present on all reels and substitutes for any symbol apart from Scatter (lightning bolt) to complete winning combinations. This makes it easier for players to create wins and increases their chances of triggering the slot’s various bonus features.

Thor has two faces: normal and bonus. The Normal Thor will substitute symbols to form a win, while the Bonus Thor appears only on reel 5. If he is part of any combination during free spins, all rewards are quadrupled!

Scatters

The Scatter symbol in Thunderbolt is represented by Lightning Bolt. It can appear anywhere on reels 1-4 and triggers Free Spins when two or more scatter symbols land together.

Three, four or five scatters landing will give you a certain amount of free games. 3 Scatters = 10 Free Games Four Scatters = 20 Free Games *Five Scatters = 30 Free Games

  2. Thunder Reels Feature : During base game play a Thunder Reel will randomly activate after each winning spin resulting in all the winning paylines paying double their usual value for that one single round.
