About this Slot
Thunder vs Underworld 250 is a Greek mythology slot from Pragmatic Play with an RTP of 98.01%, medium volatility, and a maximum win of 25,000x. The game features 5 reels, 3 rows and 15 paylines.
Expanding wilds appear across all reels and apply random multipliers to wins during the base game. When the free spins round triggers, expanding wilds lock in place until the round ends.
Three scatter symbols landing on reels 1, 3 and 5 trigger the free spins bonus, awarding 10 free spins.
The game offers two distinct modes that affect gameplay dynamics. Thunder mode increases the chance of triggering free spins but delivers lower average wins. Underworld mode reduces the free spins trigger chance while offering higher average wins.
A buy feature is available that provides direct access to the bonus round or an upgraded version of the free spins feature.
Two special bet options are also offered. The first special bet raises the stake and guarantees a wild landing with a multiplier boost. The second special bet option provides stronger multiplier support for wins during play.
