Zap Attack Online Slot Review

Zap Attack is an alien invasion-themed game from Thunderkick where cartoon extraterrestrials help you to abduct up to 5,000x your stake. They appear alongside frightened townsfolk, high card emblems, and flying saucers on a 5x5 grid crossed by 25 paylines.

UFO wild symbols can expand to fill whole reels and apply multipliers to any win and if several are in the combination their values multiply each other. Trigger a free spins feature and humans get zapped into high-paying alien symbols throughout. The bonus games can retrigger any number of times to help you grab the greatest prizes.

This often-hilarious game has a high level of volatility and average returns of 96.15%. You can play it across desktop devices, iOS, Android, or Windows mobiles at the best online slots casinos. 

How to Play the Zap Attack Slot Machine

Set among the towering mountains of the American desert, the small town of Roswealth is about to become the centre of an intergalactic invasion. A waitress, farmer, grandma, and sheriff look on in horror as a mean, green alien leads the attack across the 5 reels and 5 rows, accompanied by a sci-fi soundtrack. Playing card emblems also feature here, along with UFO and TV set bonus symbols.

There’s a delightfully weird style to the Zap Attack slot game, with lots of personality, humor, and animations to the various characters. 

You can play for between 0.10 and 100.00 per spin at any of the top Betting Sites and pick stakes via a click on the Bet button below the reels. Autoplay, Quick Spin, and a Bonus Buy options are all available.

Tap the little trophy icon above the reels of this desktop and mobile game to reach a paytable that lists symbol values and carries extra details on the features. This is a 25-line slot, and you win from matched symbols across a line, starting on the left. The lower value playing card emblems pay up to 1.5x the stake when seen on all 5 reels across a payline, with 10x your stake paid out when the alien fills a line. 

Free Spins & Other Zap Attack Slot Features

Silver UFO symbols are wild, so they have the power to act as others if they land in the right place to complete or improve a win. Golden UFOs are special Invading Wilds that expand to fill any reel they are on, making it far easier for them to complete wins. They also apply a random multiplier of 2x, 3x, 4x, or 5x to any combinations they help to create. If more than one Invading Wild is in the win, the multipliers multiply with each other, and it’s possible for your prize to get a maximum boost of 125x the base value this way.

The vintage TV set is a bonus scatter symbol, and you get 7, 11, or 15 free spins when it appears in any 3, 4, or 5 places respectively. If 2, 3, 4, or 5 scatters land in a single free spin they add 3, 4, 5, or 9 extra games to the round in that order.

Aliens will zap the unfortunate humans throughout the free spins feature. They start on the sheriff, then move onto the waitress, grandma, then the farmer. Each 10 hits on a character fills a meter and turns them into another alien, making it progressively easier to zap the next human as more and more aliens invade the reels. Filling the meter also adds one more spin to the round.

Zap Attack Slot Maximum Wins, Volatility, & Average Returns

The most you can win from the Zap Attack slot in any spin is equal to 5,000x the stake, or 500,000.00 at the maximum wager. It’s a high volatility game where wins can be less frequent than in lower variance slots, but prize values can be relatively high to make up for it. The return to players percentage is good, at 96.15%.

Our Zap Attack Slot Rating

The retro sci-fi style looks great across desktop and mobile versions of the Zap Attack slot machine, with plenty of cartoonish fun to go along with the enjoyable features. Highlights in the base games include the expanding wild with multipliers, where their values combine for a potentially huge win. 

Once the free spins trigger, the invaders get busy zapping the locals and transforming them into more high-paying aliens. Retrigger the feature and you can have just aliens, wilds, and playing card symbols in action, which can lead to the biggest wins.
