The Truth Is Out There
The Zap Attack slot machine is the latest from iGaming developer Thunderkick. The Swedish company is quickly making a name for itself in the iGaming industry.
The slot is set in the fictional town of Roswealth, a desert location that is being visited by aliens. Symbols used in the Zap Attack online slot include a sheriff, a waitress and a grotesque green alien. The slot uses striking comic book-style visuals that set it apart from other aliens-themed games.
Beamed up to the Mothership
The Zap Attack slot machine has a minimum bet of 0.1 and a maximum bet of 100.
UFO symbols are wild, and these replace all other symbols except scatters. Expanding wilds fill the reel with a green tractor beam and come with a multiplier of between 2x and 5x. If an expanding wild is part of a winning combination, the payout will be multiplied by this value.
Landing three or more scatters activates free spins. Three scatters will award seven free spins, four will award 11 and five will award 15.
During the feature, the alien can shoot mid-value symbols. After a symbol has been shot 10 times, it will turn into a high-value symbol for the remainder of the feature, and you will be awarded an extra spin. Free spins can be triggered by landing additional scatters.
The Zap Attack online slot has high volatility and an RTP of 96.17%.
