Game Overview
In a world of constant political unrest and the posing threat in the near future of an AI takeover, the last thing anyone would need is a zombie apocalypse thrown into the mix. Unfortunately, those living in the PG Soft slot world are in for just that, as a mad professor has seemingly concocted up a serum that evolves the human body into a flesh-eating zombie; nice. As for the name of the game where this grim scenario is taking place, it’s called Zombie Outbreak, a 5-reel slot with 1,600 paylines, an RTP of 96.76%, and a maximum win of 5,000x bet.
PG Soft often blend several popular mechanics into their releases, and there are a couple for you to experience in Zombie Outbreak, too. First, this is a cascading reels slot game, so all symbols involved in a winning combo are removed from the reels, and new ones then drop from above, providing extra chances to win. The headline feature in the slot, though, is the expanding wild with multipliers, which can enhance your winning combos massively if you hit a run of winning cascades. Whilst the feature is active in the base game, it’s most potent in the free spins bonus, where its value will not reset between losing spins.
I’m not sure about you, but I think I’d quite fancy staying in human form rather than being transformed into a limb-eating zombie, crikey. The best way to avoid any stray serum entering your bloodstream and joining the undead is to fire up our free Zombie Outbreak demo slot. It’s available to try out below.
Zombie Outbreak Slot Theme, Stakes, Pays & Symbols
With how obsessed we seem to be with zombie movies and TV shows, it’s a bit surprising that there aren’t hoards of slots featuring the undead. Don’t get me wrong, there is a good selection available to play, and we have some great free demo slots you can enjoy in the niche here on site, which I’ll suggest for you in a moment, but you’d certainly think there would be more. Okay, as for those recommendations. Straight off the bat, we have to point you in the direction of Playtech’s Waking Dead slot, for obvious reasons, with this being a hugely successful TV series in its own right. Then we have Pragmatic Play’s Wild Walker slot, which is also a solid option in the zombie niche, and last of all, if you want to play something a little more light-hearted, try some spins on Pear Fictions Granny vs Zombies.
It’s that time of our review when we check in on the pays section, and at the top of the paytable, we have the Scientist, worth 2.5x bet for a full line of five. She’s followed by the Blood Bag and Gas Mask, both valued at 1.5x, with the Jar of Serum and Test Tube rounding out the premium section with equal returns of 1x. Next, we have lower pays in the game, represented by the royals, and you’ll find the Ace, King and Queen returning 0.5x, whilst the Jack, Ten, and Nine all share payouts of 0.25x for a winning combo of five.
Players who are seeking out real money play on Zombie Outbreak are offered a good selection of staking options, with the minimum cost to set the reels spinning starting at €0.20, whilst the opposite end of the scale sees the max bet reach €100 a press.
Zombie Outbreak Slot Base Game & Modifiers
PG Soft’s Zombie Outbreak is set over a 4x5x4x5x4 reel matrix where 1,600 ways to win remain active on every spin. Three or more matching symbols landing on adjacent reels starting from the leftmost reel first will award a win and activate the tumbling reels feature. This will remove all winning symbols from the reels and replace them with new ones for extra chances to win.
Expanded Wild With Multipliers
The wild professor symbol can only land on reels 2 and 4. When he appears, he will expand the full length of the reel and reveal one of the following on his wild:
- Wild Values: x1 x2 x3
- Wild Values x2 x3 x5
- Wild Values: x3 x5х12
- Wild Values x5 ×10 x15
- Wild Values x10 x15 x25
Before wins are paid, the lowest multiplier value from each Expanded Wild symbol will be collected at the bottom of the reels. After the collection of the multiplier, wins are then multiplied by the multiplier value at the bottom of the reels and wins are paid. The Expanded Wild symbol will remain on the reels until the end of the spin or when all 3 multipliers have been collected.
Zombie Outbreak Slot Free Spins Feature
Landing three scatter symbols in view whilst the base game is active will trigger the bonus and award 15 free spins, with each scatter that lands and the third adding an extra 2 spins to the starting total.
Free Spins Feature
During the free spins feature, all collected multipliers from the expanding wilds are saved, applied to any wins achieved, and the total value will not reset between losing spins. Landing 3 or more scatters in the bonus round will re-trigger the feature and award 15 free spins + 2 extra spins for every scatter after the third.
Pros
- Above average RTP.
- It's possible to hit big wins in the base game because of the expanding wild multipliers.
Cons
- It can be really hard to trigger the free spins round.
- The animation of the expanding wild can be a bit annoying, especially if there isn't a win there.
Zombie Outbreak Slot Review Final Thoughts
Again, it's been great to see PG Soft move away from the Asian slot themes and create something that can appeal to all. Zombie Outbreak does just that, and although at times the base game can seem a little mundane, it is capable of producing some big hits, as is the free spins feature where the multiplier value not resetting between losing spins really does make a difference.
