100 Zombies

Zombies claw across 100 paylines in this 5x4 horror slot from Endorphina, where stacked wilds and a 10,000x max win make the undead surprisingly rewarding. The free spins bonus fires when the bio-hazard scatter lands on the three middle reels, flooding the reels with stacked wilds. Available on desktop and mobile as part of Wild.io's online slots library, 100 Zombies pairs low volatility with bonus buy access for players who want to skip straight to the horror.

What is 100 Zombies?

100 Zombies is a 5x4 video slot from Endorphina with 96.0% RTP, low volatility, 100 paylines, and a top win of 10,000x your bet. The free spins feature stacks wilds across all reels to drive the bigger payouts.

The game is structured around stacked wilds that can cover entire reel columns during the base game as well as the free spins round. That stacking mechanic is what gives the 100-payline grid genuine win potential: when multiple reels run wild simultaneously, chains of matching combinations form across many of the active paylines at once.

How To Play 100 Zombies Slot - Step By Step

Head to Wild.io and create a free account to start playing 100 Zombies.

1. Create an account at Wild.io or log in, then head to the games library and find 100 Zombies under the Endorphina filter.
2. Set your bet per spin using the stake controls. The 100-payline structure means your total wager covers all lines.
3. Spin the reels. Stacked Wilds can land on any reel in the base game, substituting for all symbols except the Scatter to complete or extend winning combinations.
4. Watch the three middle reels for the Bio-hazard Scatter. Three Scatter symbols trigger 10 Free Games. Stacked Wilds remain active throughout the bonus, and retriggers are possible if more Scatters land.
5. After any winning spin, use the Risk Game to gamble your prize on a card-color guess. You can repeat up to ten times or collect at any point.
6. Bonus Pop is available if you prefer to purchase bonus access directly rather than waiting for the Scatter to trigger naturally.

You can also deposit using various supported payment methods.

100 Zombies Slot Theme & Graphics

100 Zombies draws its setting from the zombie horror genre: undead survivors, reluctant human fighters, and the classic biohazard imagery of a post-outbreak world. The reel backdrop suggests an abandoned street at dusk, and the symbol artwork mixes low-detail card-rank icons with grotesque character portraits. The zombie mailman, grumpy man, zombie nurse, and adventurous girl each have distinct silhouettes and slightly cartoonish proportions that lean into dark comedy rather than full gore.

Endorphina built the horror atmosphere on a foundation of solid animation: symbols catch fire when they form winning combinations, and the stacked Wild column shudders into place with a low thud. The soundtrack cycles through tense, minor-key loops that escalate during spins and settle during idle moments. The 5x4 layout fills the screen comfortably on both desktop and mobile displays, and the overall color palette stays muted purple and grey with hot-orange accent lighting on wins.

100 Zombies Slot Symbols & Paytables

Understanding the 100 Zombies symbols is important because the low-value and high-value tiers pay very differently, and the Wild and Scatter drive the game's biggest outcomes. The symbols section of the paytable, combined with what you see on the reels, tells you exactly where the value sits.

Low Value Symbols

The six low-value symbols in 100 Zombies are the classic card ranks: Ace, King, Queen, Jack, Ten, and Nine. All six appear as styled letter or number icons with a zombie-theme color wash. They pay smaller amounts for combinations of three, four, or five on a payline, and they fill enough of the reel space to keep base-game wins ticking over at a steady rate. Because the game runs 100 paylines on a 5x4 grid, even a card-rank cluster across the shorter rows contributes to your total payout. The Ace group is the highest-paying tier within the card ranks but its return for five on a line is still noticeably below what the zombie character symbols offer.

• Card ranks: Ace, King, Queen, Jack, Ten, Nine. Pay up to 1.25x stake for five

High Value Symbols

The six high-value symbols in 100 Zombies are zombie and human character portraits. The Zombie Mailman and Grumpy Man form the lower tier of the premiums, paying up to 2x your stake for five on a line. The Zombie Nurse and the Adventurous Girl step up from there, worth 3.5x and 4x respectively for a five-of-a-kind. At the top sit the Man with the Baseball Cap and the Young Male Survivor, both paying 6x your stake for five in combination. When one of these top characters lands stacked and the Wild fills an adjacent reel, the payline multiplications across 100 lines can produce sharp win spikes even in the base game.

• Zombie Mailman and Grumpy Man: up to 2x stake for five
• Zombie Nurse: up to 3.5x stake for five
• Adventurous Girl: up to 4x stake for five
• Man with Baseball Cap and Young Male Survivor: up to 6x stake for five

Special Symbols

The Stacked Wild in 100 Zombies appears on all five reels and fills multiple positions in a single column, substituting for every symbol except the Scatter. It pays 10x the stake when five Wilds complete a line on their own. During Free Games the stacking tendency increases, which is the reason wins tend to scale up significantly in the bonus round. The Bio-hazard Sign is the Scatter and it only appears on reels 2, 3, and 4. Landing all three triggers 10 Free Games and awards a separate payout of 2x your total stake just for triggering. The free spins can be retriggered if three Scatters land again during the bonus.

• Wild: Stacked Wild (substitutes for all except Scatter; pays up to 10x stake for five on own)
• Scatter: Bio-hazard Sign (reels 2, 3, 4; 3 triggers 10 Free Spins with stacked wilds; pays 2x total bet on trigger)

100 Zombies Bonus Feature & Special Features

Free Games

The Free Games feature in 100 Zombies fires when the Bio-hazard Scatter lands simultaneously on reels 2, 3, and 4. The trigger pays a flat 2x your total bet as an immediate bonus, then opens 10 spins with the same stacked-wild mechanic that applies in the base game. The key difference inside the bonus is that the probability of stacked wilds covering a full reel column is higher, so full-reel wild coverage on two or more reels at the same time becomes a realistic outcome rather than a rare event. Those multi-reel wild combinations running across 100 paylines are how 100 Zombies reaches the upper range of its 10,000x max win potential. Retriggers are possible: every additional set of three Scatters on the middle reels during the bonus grants another 10 free spins, stacking onto the remaining count.

Stacked Wilds

Stacked Wilds are the mechanical backbone of 100 Zombies and operate in both the base game and the Free Games round. Endorphina programs them to land on any reel, stacked vertically so they can fill two, three, or four positions in a single column. When a stacked wild aligns with high-value characters across the 100 paylines, each payline that completes a winning combination pays out independently, meaning a single spin can resolve multiple wins at once. The Wild also has its own pay value: five Wilds on a payline pay 10x your stake. In the Free Games the density of wild stacks increases, creating the conditions where two or three adjacent reels simultaneously carry full-column wilds. That is the scenario that drives the largest payouts in the game.

Bonus Pop

Bonus Pop is a bonus buy feature in 100 Zombies that lets you pay a fixed multiplier of your base stake to directly enter the Free Games round, bypassing the organic Scatter trigger entirely. This is useful for players who want to focus their session on the bonus feature without spending spins waiting for three Bio-hazard Scatters to align on reels 2, 3, and 4. The cost varies based on current RTP and is displayed in the interface before purchase. Bonus buy slots come with a reminder that while you access the feature faster, the total wagered over a session can be higher than the organic route.

Risk Game

The Risk Game in 100 Zombies is available after any winning spin. Endorphina's classic gamble feature asks you to predict the color of a face-down playing card: red or black. A correct guess doubles your current prize; an incorrect guess forfeits it. You can repeat the gamble up to ten times in succession, which means a correct streak could theoretically multiply a modest win into a much larger amount. The feature is entirely optional and the decision to risk or collect appears in a clear pop-up, making it easy to skip if you prefer to lock in your winnings.
