Zap Attack! is a 5x5 video slot from Thunderkick that combines a retro 1950s alien invasion theme with high-volatility gameplay and rewarding bonus features. Set in the quirky desert town of Roswealth, the game offers expanding multiplier wilds and an evolving free spins feature that can significantly boost winning potential. With a maximum win of 5,000Ă— the base bet, Zap Attack! is designed for players who enjoy volatile slots with engaging mechanics and strong bonus round potential.
Zap Attack! is played on a 5x5 reel grid with 25 fixed paylines. Winning combinations are formed across the paylines using matching symbols, while UFO Wilds substitute for all regular symbols except the TV Scatter. When a winning combination includes a UFO Wild, it expands to cover the entire reel and applies a random multiplier of 2Ă—, 3Ă—, 4Ă—, or 5Ă—. If multiple expanding wild reels appear in the same winning combination, their multipliers multiply together, creating the potential for substantial payouts. Landing TV Scatter symbols triggers the Invasion Free Spins feature.
Zap Attack! features a playful B-movie science fiction theme inspired by classic 1950s alien invasion films. The action takes place in the fictional desert town of Roswealth, where UFOs, ray guns, and green aliens confront a cast of quirky human characters including a sheriff, waitress, grandma, and farmer. High-quality animations, expanding wild effects, and an energetic retro-inspired soundtrack reinforce the light-hearted extraterrestrial atmosphere.
The Invasion Free Spins feature introduces symbol transformations that increase the value of the reels throughout the bonus round.
