Zombie Invasion is a slot by Dragon Gaming that puts you in the middle of a zombie apocalypse. Apocalyptic slots featuring zombies aren’t anything new, but to be honest, this infected city game does things better than most. It’s a medium-high variance math model with a return to player (RTP) of 94% and 30 paylines. While it doesn’t look that impressive initially, multipliers and free spins will change your mind. Read our Zombie Invasion online slot review below and see why it’s worth a try in a sea of zombie slots.

Themes in Zombie Invasion

Zombies―or a zombie virus―are the basis for this infected city game. Developed by Dragon Gaming, it comes with high-quality graphics and superb animations. This isn’t your standard zombie game, a la Plants vs. Zombies. These zombies and the group of survivors look and feel very real. We’ll go on a hunch and say that The Walking Dead has inspired this slot game. Regardless, Dragon Gaming has done a great job with the look, feel, and math model, too, which is better than penny slot machines.

Zombie Invasion Symbols

The symbols in Zombie Invasion show blood-thirsty, brain-eating zombies and a group of survivors with an arsenal in their hands. It’s an epic battle between the undead and the living and one that very much feels real. We can congratulate Dragon Gaming on making the symbols look so sharp―it’s like the zombies will jump out of the screen.

Regular Symbols

The regular cast of symbols shows a group of survivors with weapons, including everything from bloody cleavers to guns―essentially, a heavy arsenal that can easily destroy zombies. These are the high-paying symbols, and low-paying card royals accompany them, stylized to suit the theme.

Wild Symbols

The wild symbol is a regular “W.” It substitutes for other symbols in winning combinations. Unlike new online slots, it doesn’t have a paytable, but it does open the doors to bigger wins on a single spin.

Bonus Symbols

The hazard symbols scatters trigger the free spins bonus game. This is where the gameplay takes a turn, allowing you to kill zombies quickly with the weapons and turn the odds in your favor.

Paytable and Winning Combinations

Zombie Invasion has a regular paytable and math model. It’s a medium to highly volatile slot with a base game and free spins. You can expect varied wins if you get lucky. The highest-paying symbol pays up to 500x for five and only pays for two matching instances. Random wilds can spice up the gameplay in the random wild feature. As expected, there’s the free spins round and an additional bonus game entitled Escape Infected City. In it, you’ll do your best to escape the infected city and hordes of zombies by opening doors that either lead to an exit or your loss. The free spins bonus game comes with all active features and possible retriggers. You can earn up to 20 free spins initially for five scatters and repeat that with no cap on the number of spins. The betting range goes between $0.30 and $90 per spin.

Zombie Invasion Slot Paytable 1
  • Survivor #1: 500x for five, 200x for four, 100x for three, and 10x for two.
  • Survivor #2: 250x for five, 150x for four, and 75x for three.
  • Survivor #3: 375x for five, 150x for four, and 25x for three.
  • Survivor #4: 250x for five, 50x for four, and 15x for three.

Free Spins and Bonus Rounds in Zombie Invasion

As mentioned earlier, the Zombie Invasion online slot has two bonus rounds to look forward to. One is a free spins round, while the other is a mini-game that ups the stakes. The random wilds feature isn’t a bonus, technically, but it’s still a great way to hit the higher payouts.

Zombie Invasion Bonus

Escape Infected City Game

The bonus game is triggered when three expanding zombies―runners and the cop land on reels 1, 3, and 5. The game has five levels with five doors in each. You pick the doors in the Infected City bonus game, resulting in a win or a loss. You’ll go to the next level and receive a multiplier if it’s a win. The Escape Infected City bonus ends when you open a losing door. It can’t be retriggered from within.

Free Spins Bonus Game

Per the online slot guide, you need three or more scatters to receive up to 20 free spins. This bonus plays like the base game, except you’re not paying for the spins. You can earn more free spins during the feature by landing scatters.

Random Wild Feature

When a smoke bomb appears anywhere on the reels, it triggers the random wild feature. Up to one wild is added on the reels from left to right in random positions, possibly leading to a big prize. Because it’s a medium-high variance slot, you can expect this feature frequently and in the bonus round.
