How the Game Plays

Zap Attack is a sci-fi themed slot from Thunderkick set in the dusty desert town of Roswealth. The game utilizes a 5x5 grid where winning combinations are formed across 25 fixed paylines. Visually, it adopts a retro 1950s aesthetic, featuring a cast of local characters like a sheriff and a farmer alongside extraterrestrial invaders. The core loop centers on high-value alien symbols and the dynamic behavior of the game's wild symbols.

Expanding Multiplier Wilds Explained

The UFO wild symbols are central to the base game. When a wild lands, it has the potential to expand and cover an entire reel. These expanded wilds also carry random multipliers of 2x, 3x, 4x, or 5x. If more than one multiplier wild contributes to a single win, their values are multiplied together, allowing for a total win multiplier of up to 125x.

Invasion Free Spins Explained

Triggered by landing three or more TV scatters, the bonus round awards between 7 and 15 free spins. During this feature, the alien symbol uses a ray gun to "zap" human character symbols. Each zap is collected in a meter corresponding to that specific character. Once a meter is filled after ten hits, that human symbol is permanently upgraded to the high-paying alien symbol for the remainder of the round, while also awarding an additional free spin.
