Players will be transported to a Western town where an alien attack is underway. On its five reels and 25 paylines, players will find an array of symbols including aliens and plenty of human characters.

Bonus features in this game include an expanding wild multiplier of up to 5x and a free spins round where the alien will zap human character symbols on the reels to create more high value symbols and award additional free spins. The max win available in this alien attack is 5,000x your stake.

If you think this could be the slot game for you, carry on reading our Zap Attack review for all the information you need to know about this game.

How to Play

Bets per spin range from as little as 10p up to £100. Winning combinations are formed in this game by landing three or more matching symbols across adjacent reels. This must start from the leftmost reel and moves from left to right.

The symbols on the reels of this game are:

  • 10
  • J
  • Q
  • K
  • A
  • Farmer
  • Grandma
  • Waitress
  • Sheriff
  • Alien
  • Spaceship wild
  • Spaceship expanding wild
  • BONUS scatter


In the base game, the highest value symbol on the reels is the Alien and it can award up to 10x your stake for five or more in a winning combo. With the special features in play, there is the chance to win up to 5.000x your bet.

Special Features

There are two special features in the Zap Attack slot game including expanding multiplier wilds and free spins feature.

Watch out for the spaceship expanding wild symbol which can expand to cover entire reels. Not only that, it can carry a multiplier of 2x, 3x, 4x or 5x which is then applied to any winning combos that it is part of.

The BONUS scatter symbol will trigger the free spins bonus round when it lands three or more times on the reels. The more scatter symbols you land, the more free spins you will be awarded:

  • 3 scatters – 7 free spins
  • 4 scatters – 11 free spins
  • 5 scatters – 15 free spins

As you play this round, the alien symbol will get out his zap gun to shoot a human character symbol on the reels. Each time it gets a hit, this will be collected and used to fill the meter. After 10 hits, one symbol will transform into a high-value alien symbol for the rest of the round and one additional free spin is awarded.

Graphics and Sounds

Thunderkick has done an awesome job in creating the theme and graphics for Zap Attack. This game combines the Sci-FI alien theme with the wild west as you are transported to a western town with canyons, campervans and cacti behind the reels.

The graphics almost have a retro arcade feel to them! The lower value symbols are represented by the standard playing card symbols while the high value symbols include an array of human characters such as a waitress, farmer, sheriff and grandma plus an alien symbol. Spaceships also make an appearance in the form of wild symbols. As you spin the reels, a galactic themed soundtrack plays in the background which could not work any better with the overall theme of this game.


If you love Sci-Fi themed slot games, you cannot go wrong spinning the reels of Zap Attack. Thunderkick has created a fantastic slot game which combines high-quality graphics and cool theme with exciting bonus features. The alien zap attacks during the free spins round are great plus there are lots of potential wins to be had with the expanding multiplier wilds. Take part in this alien adventure to try and secure wins of up to 5.000x your stake.
