Thunder vs Underworld 250 Slot Features
Wild Symbol
The Wild substitutes for all symbols except Scatter and can appear on any reel.
Expanding Wilds with Multiplier
These Expanding Wilds can land on any reel. When one hits in the base game or Free Spins and a win is possible, it expands the full reel and takes a random multiplier of 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 20x, 25x, 50x, 100x or 250x. It applies to every winning combination it is part of, and if multiple Wilds share a win, their multipliers add together.
Free Spins
Scatters appear only on reels 1, 3 and 5 in the base game. Land 3 to trigger Free Spins with 10 free spins. During the round, any Expanding Wild that hits expands, takes a random multiplier from the same values as the base game and stays on screen for all remaining free spins. The feature cannot be retriggered, and special reels are used.
