Game Information & Statistics

For players seeking a quick overview of the technical aspects, here’s a detailed table of Thunder vs Underworld’s core features:

Theme, Graphics, and Symbols

Thunder vs Underworld thrusts players into an electrifying clash between the Greek gods Zeus and Hades. The online slot’s theme is a grand mythological battle, allowing players to choose their allegiance, which dynamically alters the game’s appearance. The Thunder mode (Zeus) is set against an ancient temple bathed in bright blue lightning, while the Underworld mode (Hades) features a darker setting with a fiery gateway, creating incredibly atmospheric environments for this casino game.

The graphics are crisp and highly detailed, with symbols that change to match the chosen profile. Stunning animations, particularly when expanding wilds cover reels or multipliers activate, add dynamic flair to the gameplay. The sound design features an epic orchestral soundtrack that perfectly complements the mythological narrative, building tension and excitement during gameplay, enhancing the overall immersive online slot experience.

Symbols and Payouts

• Regular Symbols: The low-paying symbols are glossy card royals (10, J, Q, K, A). Higher-paying symbols include mythological artifacts like chalices, helmets, phoenixes (Thunder mode), Lernaean Hydras/Nemean Lions (Underworld mode), and the deities Zeus and Hades themselves. Zeus and Hades are typically the highest-paying regular symbols.
• Special Symbols:
  • Wild Symbol (Olympus/Hades Badges): Special badges for Olympus and Hades act as the wild symbols. They substitute for non-special symbols and appear on all reels. If they can lead to a win, they expand to cover the entire reel.
  • Multiplier Wilds: Expanding wilds come with a random multiplier ranging from 2x to 100x. If multiple multiplier wilds are part of the same winning combination, their multipliers are cumulative, significantly boosting the potential payout.
  • Scatter Symbol: A distinct scatter symbol (often representing a portal or a clash of elements) triggers the free spins feature. Scatters land only on odd-numbered reels (1, 3, 5).

Bonus Features and Mechanics

Thunder vs Underworld is packed with thrilling bonus features designed to enhance your gameplay and deliver significant payouts:

• Dual Modes (Thunder vs Underworld): Choose between Thunder Mode (high volatility, 98.04% RTP) which increases the chance of triggering free spins but with generally lower payouts, or Underworld Mode (very high volatility, 98.00% RTP) which decreases free spins frequency but offers significantly higher potential rewards.
• Expanding Wilds with Multipliers: Wild symbols (Olympus/Hades Badges) can appear on all reels. If a win is possible, they expand vertically to cover their entire reel and are assigned a random multiplier from 2x up to 100x. If multiple expanding wilds are part of the same winning combination, their multipliers are cumulative.
• Free Spins with Sticky Wilds: Landing three Scatter symbols on reels 1, 3, and 5 triggers 10 free spins. During this round, any expanding wild that hits will extend, adopt a random multiplier, and crucially, remain sticky for the rest of the free spins, leading to potentially massive payouts. Free spins cannot be retriggered.
• Bonus Buy: Players can instantly trigger free spins with four options:
  • Thunder Mode Standard Free Spins (75x bet)
  • Thunder Mode Special Free Spins (300x bet, guaranteed expanding wild with multiplier on first spin)
