How To Play 100 Zombies Slot

100 Zombies is played across a 5×4 grid of reels with 100 pay lines. The slot pays out when you get three or more matching symbols on a payline, but the best chances to win big are in the Free Spins Bonus round.

Bets start from as little as £0.20 per spin and reach a huge maximum of £1000 per spin for the high rollers out there.

You’ll first need to decide on your coin value which ranges between £0.01 and £1 per coin. Then you’ll need to decide on how much you want to bet on each spin and across how many of the 100 paylines.

The maximum payout in the game is 10,000x your stake, which is achieved by filling the screen with Wilds on every free spin in the bonus round. It might be possible, but it’s highly unlikely.

Fortunately, you will have plenty of other opportunities to win big prizes.

100 Zombies Symbols

The slot symbols can be separated as follows:

  • Low-paying symbols: J, Q, K, A.
  • High-paying symbols: Zombie Policeman, Old Grumpy Man, Zombie Nurse, Adventurous Girl, Big Zombie, Young Fearless Male.
  • Wild: A yellow box with "WILD" written on it.
  • Scatter: A yellow and green biohazard warning symbol with "SCATTER" written underneath.

If the names seem a little arbitrary, that's because they aren't specifically mentioned in the slot. We've inferred them from what Endorphina have written on their website.

For low-paying symbols, three-of-a-kind pays 0.05x your bet size, while five-of-a-kind pays 1-1.25x. For high-paying symbols, three-of-a-kind pays 0.1-0.5x your bet size, while five-of-a-kind pays 2-6x.

Wild symbols pay the most, paying up to 10x for five-of-a-kind. The Wild symbol can substitute for all symbols except for the biohazard warning scatter symbol.

The main purpose of the Scatters is to get you to the Bonus round, but matching gives you a 2x payout before you go there.

100 Zombies Slot Features

This slot is very straightforward when it comes to the Bonus round and features. It's all about the stacked Wilds!

Bonus Round and Free Spins

To trigger the free spins, you will need to land three Scatter symbols on reels 2, 3, and 4 simultaneously. You will be awarded ten free spins that can be retriggered by landing more scatters.


Although they do also appear stacked in the base game, all Wilds in the free spins round will be stacked Wilds which gives you even more opportunity to create winning combinations.

Just landing five Wilds will give you a payout of 10x your stake, but the stacked Wilds mean that – with a bit of luck – you can get significantly higher payouts.

Risk Gamble feature

After every win, you will have the chance to double your winnings up to 10 times. You will be shown a dealer card face-up.

All you have to do is pick one of the four face-down cards and reveal a higher card. If you are successful, your winnings will be doubled. If you fail, you will lose your winnings. It's worth noting that the joker beats all other cards.

Naturally, the dealer wins more often than not here. Still, if you play it smart and only play when the dealer card is low, you can improve your chances of doubling your money!

Bonus Pop Buy Feature

Like many slots nowadays, 100 Zombies comes with a Bonus Buy option that lets you skip straight to the Bonus. As you might expect, this costs a pretty penny: 28x your stake size.

You should always have clear betting limits when playing slots, but be particularly careful with Bonus Buys. While you do save time and have significantly more chances to win big, you can just as easily lose big and fast.

Graphics and Theme

The game is set in an apocalyptic city, in a dystopian future where society has collapsed, and Zombies have taken over. Our hero vigilantes are forced to take action into their own hands, and you're there to help them! The visuals and soundtrack for this slot are fantastic and do great justice to the genre.
