THUNDER ROCK

About this Slot

THUNDER ROCK is a Greek mythology slot from Olimp with an RTP of 96.5%, high volatility and a maximum win of 25,000x. The game uses 6 reels, 5 rows and cluster pays, requiring 8 or more matching symbols anywhere on the board to form a win. Wild Symbol and Re-Spin mechanics power the base game, while Sticky Wilds remain in place across multiple spins. A Multiplier system combines with Symbol Transformation and Symbol Removal to reshape the board after each win. Divine Spins trigger when you collect 4 Golden Laurels anywhere on the board. You start with 20 spins, and 5, 6 or 7 Laurels raise the total to 24, 28 or 30 spins respectively. Every additional Laurel beyond 7 adds 2 more spins, and landing 3 Laurels on a single spin retriggers 6 extra spins. Lightning Orbs land as regular symbols with multiplier values ranging from ×2 to ×25. When a winning combination forms, all Orb values on the board add together and multiply the total win. During Divine Spins, they feed a persistent multiplier that continues stacking across the feature. The God Column is a wild reel that appears randomly each spin and fills an entire reel for that round. It matches symbols across all five rows and applies a god cut to wins. Base play features Hermes or Ares, while higher modes unlock stronger gods with greater impact. The Thunderstone lands randomly after the board reveals, sometimes twice on a single spin. It destroys a 3×3 area around its landing position, though Laurels, Orbs and KRATOS symbols resist destruction. This creates fresh tumble opportunities by clearing other symbols. The Hades Cut functions as a normal symbol but only affects winning sequences on the final board. Each one halves the pending Lightning Orb total, rounding up, though it never reduces multipliers below ×1. Seal of Rebirth upgrades 1 to 3 low symbols into the same premium symbol after the reels reveal. This transformation can complete 8-symbol matches and trigger tumbles without additional player input. Four bonus buy options are available: BLESSING THE SEAL REFORGES at 100x bet, FAVOUR A BOLT ON MOST SPINS at 250x bet, THE LONG STORM at 500x bet, and STORM KING THE GOD HOLDS HIS REEL FOR THE NEXT SPIN at 1,000x bet.
