Theme

9 

Triple Thunder is inspired by myths from different cultures and features three well-known gods of thunder, namely Zeus, Perun, and Thor. The game has bright graphics and smooth animations as well as an epic soundtrack. The playing matrix is placed against the background of thunderclouds and the 3 gods and their respective feature meters are drawn on the left of the reels.

The game’s paytable consists of only seven symbols. The blue gem with a Whirlwind and the red gem with the Thunderbolt pay 0.2x to 3x the total stake, while the green and yellow ones with Thor's Hammer pay 0.3x to 4x the player's bet. The light-blue and violet gems pay out 0.4x to 8x the bet. Although the game has a Scatter icon, it doesn't offer cash rewards.

Bonus Rounds & Free Spins

7.9 

Thunder Meter

Each god has two icons associated with them that fill their corresponding Thunder Meter when you hit winning combos. For example, filling Thor's Thunder Meter with Hammers activates a Giant Symbol on the matrix. Zeus' Thunder Meter can be filled with Thunderbolts to activate Zeus' Lightning Path on the grid. Meanwhile, ten Whirlwinds in Perun's corresponding meter trigger Perun's Stormy Wild on the reels.

Free Spins

The Scatter icon of this game is the golden letter S. When players land five Scatters anywhere on the grid, they trigger the Triple Thunder Free Spins. Players can choose one of the gods – Thor, Zeus, or Perun – to activate their exclusive features, which determines the number of free spins (10, 8, or 4) and win multiplier value (2x, 4x, or 8x).

I came across a very interesting slot, which has cascades and additional features. Naturally, I didn’t reveal the full potential of the slot, either I was unlucky, or it was just the machine. I was spinning the reels at €0.50. In the beginning, I blew up an avalanche up to €0.85, and at the very end, I was able to take €1.20 (2.4x). This is the most valuable thing I got from this game. Yes, in the end, I was dissatisfied, though I gained valuable experience.
