Zap Attack Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 25 paylines

Stakes Range: 10p to £100 per spin

RTP: 96.15%

Max Win: 5,000 x bet per spin

The Zap Attack slot is played on 5 reels and has 25 fixed paylines. The setup is actually a 5×5 grid but it’s not a typical grid slot. Wins are formed by matching 3 or more symbols on adjacent reels from left to right, beginning from reel 1.

The minimum stake is 10p and the maximum is £100 per spin. Catering to all bankrolls, hit the ‘bet’ icon below the reels to adjust your total stake. There are 14 predefined values to choose from.

The Zap Attack RTP is 96.15%, which is above the industry average for slots at UK online casinos. In terms of volatility, it’s in the high range, so don’t expect big wins too often. It’s been rated 9.42 out of 10 by the provider for volatility.

The maximum win is 5,000 x the bet. This is best achieved in the Free Spins feature as there is no upper limit on the number of free spins that could be won. More on that further down in the review.

Theme: an exciting extraterrestrial experience

Theme: Sci-Fi

High Value Symbol: Alien

Compatibility: Mobile, Tablet, Desktop

zap-attack-slot-base-game

The alien and human mix has been done really well here in this Sci-Fi creation. The reels in the Zap Attack slot game are set in the fictional town of Roswealth, which looks like it’s in the Wild West. The audio is a mix of Western and Sci-Fi too, which adds to the overall appeal.  It reminds me a little of programmes like Futurama whenever this theme is introduced. The graphics are solid and the soundtrack fits well.

Land the Free Spins feature and the background turns green as the audio intensifies. The animation with the Alien symbol zapping the human characters is a nice touch. So too are the Expanding Wilds. It really enhances the overall gameplay in my opinion.

On the reels, the A-10 Royals are the lower-paying symbols. These are joined by human characters in the form of a farmer, a grandma, a waitress and a sheriff. The Alien symbol pays the most, awarding 1, 2, 3.5 or 10 x the bet for 2, 3, 4 or 5 in combination respectively. Here’s a breakdown of the symbols you will come across in the game and their payout info:

Zap Attack Mobile

zap-attack-mobile-slot

Released on the 13th of September 2023, the Zap Attack mobile slot is available to play on mobiles, tablets and desktops at the best mobile UK casinos. Compatible with all iOS and Android smartphones, it plays really well on smaller screens.

Zap Attack Bonus Features

There are 3 bonus features in the Zap Attack slot game. First up is an Expanding multiplier Wild that expands to fill the whole reel with multipliers up to 5x. Then there’s a Free Spins feature with no upper limit on the number of free spins available. Non-UK players can also buy the Free Spins feature for a price. Read on as we explain how all of the bonus feature work.

Expanding Multiplier Wilds

Expanding Multiplier Wilds will expand when they land to cover an entire reel with a random multiplier of 2x, 3x, 4x or 5x if it’s part of a winning combination once expanded. The payline win is multiplied by their multipliers. For example, one with a 2x multiplier and one with a 3x multiplier will give you a total multiplier of 6x. The maximum multiplier from Expanding Multiplier Wilds forming part of a win is 125x (5x5x5).

Free Spins feature

zap-attack-slot-free-spins-feature

Land 3 or more Scatters in the base game of the Zap Attack slot to trigger this bonus feature. Here’s how many free spins you could get depending on the number of Scatters that land in the base game:

  • 3 = 7 free spins
  • 4 = 11 free spins
  • 5 = 15 free spins

The Alien symbols carrying zap guns will randomly shoot one of the human characters during the bonus round. Each hit is collected and this happens in a set order – Sheriff, Waitress, Grandma and Farmer. A meter is filled with 10 hits, and when this happens, that corresponding symbol turns into the Alien symbol for the rest of the bonus round. You will also get 1 extra free spin when a meter is filled.

Land 2, 3, 4 or 5 Scatters during the bonus round to get 3, 4, 5 or 9 extra free spins respectively

Originality








I think Thunderkick has done a great job with the Zap Attack slot in terms of theme, visuals and audio. It all ties into each other brilliantly and looks fantastic on smaller devices as well as desktops. Add in the above-average RTP rate of 96.15% and 5,000 x max wins and you’ve got a very nice-looking slot on the surface, Then you add in the bonus features, which you may have come across in previous titles such as Pink Elephants 2 with the low and high symbol transformations, and you get a slot that’s well worth your time and money.

The Expanding Multiplier Wilds is the feature that sticks out for me. It really enhances the overall gameplay alongside a fun base game and an action-packed Free Spins feature. Overall, even if you’re not a fan of the theme, I’m pretty sure you will enjoy this one. Not sure? Try our free demo first and decide for yourself.

A couple of superb outer space alternatives include Space Miners from Relax Gaming and Space Stacks by Push Gaming. They both have some great bonus features and 50,000 x and 5,000 x max wins respectively.

Pros
  • 5,000 x bet max wins
  • Multipliers up to 5x
  • Unlimited free spins
Cons
  • Highly volatile (9.4/10)
  • No unique features
