As you approach the grid, you are immediately transported to the entrance of a majestic floating temple. The temple is suspended in the air by a series of hovering rock masses, each supporting a different structure. These structures range from intricate statues to towering spires, all of which contribute to the temple’s grandeur.

As you explore the temple, you are enveloped in the ancient soundtrack that plays in the background. The music is haunting and ethereal, adding to the mythological ambiance of the temple.

Symbols and Features


The symbols in Thunder Wheel slot game range in value, with the lowest-ranking combinations being the Spades, Hearts, Diamonds, and Club coins, which offer payouts ranging from 0.4x to 0.45x the bet. 

The Cerberus and Sir symbols pay 0.25x and 1x for three or four of each, while the Minotaur and Harpy symbols offer 0.5x and 1.5x for three or more. The Heart symbol gives out up to 3x the bet, while the most valuable symbol, Zeus, offers a payout of 5x the stake.

In addition to these regular symbols, the slot also features special symbols that activate various bonuses. The Logo and Bonus signs trigger Thunder Wheel bonus and free spins, respectively. The “W” symbol serves as a wild card that can replace all non-special symbols.

The Expanding Wild is a random bonus feature that can occur during the base game and expands to cover up to a 3×3 area, increasing the chances of winning combinations.

The Moving Wild is a feature that is activated during the free spins, with the Bonus symbol accumulating in a Collect Meter. When the meter becomes full, the Expanding Wild is unlocked, and additional free spins are triggered in the following stages:

  • Stage 1: five Bonus symbols expand the Moving Wild to a 1×2 size with an additional two spins.
  • Stage 2: four Bonus symbols expand the Moving Wild to a 2×2 size with an additional two spins.
  • Stage 3: four Bonus symbols expand the Moving Wild to a 3×2 size with an additional two spins.
  • Stage 4: three Bonus symbols expand the Moving Wild to a 3×3 size with an additional two spins.
  • Stage 5: three Bonus symbols expand the Moving Wild to a 4×4 size with an additional spin.

The Logo symbols are not active during the free spins, but landing two or more on the reels will unlock rings on the Fortune Wheel. If a zero is landed on the second or third ring, another round is triggered, with the potential to win up to 9999x the bet.

Players also have the option to instantly access the Bonus Feature by using the Buy Bonus option at a displayed price. Thunder Wheel RTP when using this option is 96.37%.
