Game Review

Zap Attack Slot

Zap Attack is a wonderful slot by Thunderkick that players enjoy with thrilling features, mechanics, and surprises. Take a look at our review below and learn more about this video slot!

Enjoy the thrill of Thunderkick's Zap Attack and get the chance of winning up to 5000x your bet!

Theme, Soundtrack and Symbols

The theme of this video slot is all about the aliens! They’re here, and they’re ready to rule. Thunderkick was obviously inspired by the 1996 film Mars Attacks, but these aliens have headed for Roswealth (as a shout-out to Roswell).

Spooky sci-fi music makes for the perfect soundtrack to this invasion slot. But don’t fret; you don’t have to grab your shotgun or shovel just yet because there are a number of townspeople ready to take on the invaders.

Or perhaps they’re not entirely ready… The symbols on the reels include a yellow sheriff, a blue farmer, a pink waitress, and a purple grandma. These are the high-paying symbols. Low-value symbols include standard A, K, Q, J, and 10 icons.

Then there’s the alien himself (who can take on the appearance of other symbols), as well as the TV screen Scatter and the UFO Wild.

Game Mechanics

Zap Attack is all about the action, and this online slot has plenty to offer with a high variance and an RTP of 96.15%. It’s set on a 5x5 game grid with 25 paylines. Wins are paid out from left to right as aliens attempt to take down the townspeople.

Start playing by placing your bet and hitting the spin button. You can play for as little as €0.10 per spin or a maximum of €100. The maximum win up for grabs is 5000x your bet, so play responsibly and make the most of each round.

Special Features

Zap Attack has a couple of special features to look out for as you spin the reels. Here’s what you can expect to find as you play.

Wild Symbol

The UFO descending from above is the Wild symbol and will substitute for all others (except the Scatter) to create wins.

Expanding Multiplier Wilds

Invading Wild symbols will expand to cover an entire reel. It will also add a random multiplier of either 2x, 3x, 4x, or 5x to boost any winning combinations that may be created.

Free Spins Bonus Game

Land 3 or more Scatter symbols during the base game, and you’ll receive up to 15 free spins. If you manage to land 2 or more Scatter symbols during the bonus game, you’ll receive between 3 and 9 extra free spins.

As the bonus game plays out, the high-value alien symbol will appear to shoot down humans. If he hits one with his ray gun, it will push the symbol to the right of the reels. A meter will start to climb with each hit. When it reaches 10 hits, the last symbol that was blasted will transform into another high-paying alien! An additional free spin is also added to the tally.

Play ‘On The Go’

You don’t have to deal with alien invasions at home; you can take the fun on the go with this Thunderkick creation. You can always count on this software provider to ensure that its games are top-tier and run perfectly on mobile devices.

The game will adjust ever so slightly to account for a smaller screen size, but other than that, the experience will remain the same. You can play your way to wins of up to 5000x your bet from your bed, your couch, or while on the train. It’s your invasion party!

CasinoWow Game Verdict

If you’re a fan of sci-fi slots or alien films, we highly recommend checking out this high-volatility creation, Zap Attack. Perfectly designed for new and experienced players, we love that it has a fun theme, great bonus features, and a betting range to suit any pocket.

Play the demo at CasinoWow, or play for real money at one of our recommended Thunderkick online casinos.
