Thunder vs Underworld is a casino slot from Pragmatic Play where you go on a trip through Greek Mythology. In this game, you can plead your allegiance to Zeus or Hades, moving from Olympus to the underworld, changing volatility on the fly as you play in between spins. This mechanic has been seen before, as this game is a clone of Zeus vs Hades - Gods of War that was released the year prior, with the same features and similar stat spread. We’ve seen this happen before with multiple other Pragmatic Play games, especially with their Gates of Olympus series.

If you haven’t played the original, then let me give you the rundown of Thunder vs Underworld with its focus on Expanding Wilds that can come with multipliers of up to 100X. During the Free Spins, these Expanded Wilds will stick to the grid, helping you get closer to the max win of 15,000X the bet.
