How Thunder vs Underworld works
Thunder vs Underworld runs 5 reels with fixed paylines. Stakes in the real-money version run from 0.1 to 100 per spin; the demo uses virtual credits instead. Because the demo uses the same maths as the live game, it is a fair way to see how often the features actually land before deciding whether the game suits you.
