Rules and Gameplay

The Triple Thunder slot by Tom Horn Gaming introduces players to an innovative and engaging gameplay experience set within a 5×5 grid. Unlike traditional slots, Triple Thunder eschews standard paylines for a cluster pays mechanism, where wins are achieved by landing clusters of 5 or more matching symbols. The game’s thematic essence is captured through its homage to mythic gods associated with thunder—Perun, Thor, and Zeus—blending their legendary powers into the gameplay. Players can adjust their bets from $0.50 to $100 per spin, making it accessible for low and high rollers alike. The game’s RTP ranges from 92.35% to 95.02%, indicating the return players can expect over time.

Triple Thunder is packed with a variety of bonus features that enhance the gaming experience and increase winning potential:

  • Free Spins: Landing 5 Scatters triggers the Free Spins feature, allowing players to choose a god for their free spins, each offering a different number of spins and win multipliers.
  • Bonus Buy Feature: Players have the option to purchase the Free Spins feature for 80x their bet, providing direct access to this exciting part of the game.
  • Cascading Wins: The Cascading Wins feature removes winning symbols from the grid, allowing new ones to fall into place and potentially create additional wins.


The symbols in Triple Thunder are both visually appealing and integral to the game’s mechanics. Here’s a breakdown of the main symbols:

  • Colored Gems: Six types of gems represent the pay symbols, each associated with different elements of the theme, like tornadoes and hammers.
  • Scatter Symbols: Scatter symbols trigger the Free Spins feature, key to unlocking the game’s major bonuses.


Payouts in Triple Thunder are determined by the type and number of symbols in a cluster, with a maximum win potential of 440x the bet. Here’s a brief overview of potential payouts:
