Overview of 100 Zombies Slot

100 Zombies is an exciting online slot from prominent game creator Endorphina set in a post-apocalyptic world overrun by the undead. With 5 reels, 4 rows, and 100 paylines, this slot aims to provide an immersive horror experience through chilling visuals and engaging gameplay features.

The graphics and audio of 100 Zombies are designed to vividly bring the zombie apocalypse setting to life. The reels are set against a devastated city street with smashed cars and flaming barrels. Undead zombies limp across the screen and through the reels, some wearing ripped police uniforms or bloody lab coats.

The higher value symbols incorporate characters actively fighting the zombie threat like an elderly man with a rifle, a blonde woman firing a pistol, and a tough-looking man wielding a spiked bat. The imagery perfectly captures the constant danger and dread of a world overrun with ravenous zombies.

Haunting zombie shrieks and groans play in the background, along with dramatic orchestral music suites.

Small details like scratch marks on symbols and blood spatter on the borders enhance the horror aesthetic. Every component aims to put players on edge, evoking a sense of trying to survive and fight back against a relentless zombie onslaught.

Presentation and Symbols

The post-apocalyptic city backdrop sets an eerie scene amidst the outbreak. Grumpy and adventurous human survivors do battle with zombie nurses, mailmen and more across the 100 ways to win. Card symbols and wild and scatter symbols round out the options.

With medium volatility, the slot has an RTP of 96% – slightly above average. Bets range from $0.20 to $1000 per spin, accommodating various bankrolls. However, the max payout of 10,000x the stake is quite standard.

Symbols and Paytable

The lower paying symbols in 100 Zombies are represented by the classic playing card suits hearts, spades, diamonds, and clubs. The card suits take on a gruesome zombie style, appearing cracked, burned, and splattered with blood. They pay out relatively small rewards.

Higher value symbols depict more detailed zombie characters, some with backstories suggested like the zombie nurse and police officer. Different zombie types include a muscular bald zombie, a pale zombie peering over its shoulder, and an undead woman zombie with long hair.

The maximum paying symbol is the Wild, which substitutes for all other symbols except the Scatter to help form more winning combinations. When 5 wilds land, they award a 10x multiplier on the spin bet.

The Scatter symbol is depicted by a glowing biohazard symbol. Landing this Scatter across the reels can lead to big payouts and activate the rewarding free spins features.

While not revealed explicitly by the developer, the estimated maximum possible win in the 100 Zombies slot is 10,000x the player’s bet amount. This can be achieved by filling all reels with stacked wilds during free spins for huge multipliers.

Even in base gameplay, the stacked wilds combined with 100 paylines generate frequent medium sized payouts to keep the zombie hunting exciting. The free spins and Gamble feature offer further opportunities at big rewards.

Gameplay Features and Mechanics

100 Zombies incorporates several features into its gameplay beyond just landing symbol combinations across paylines. First, wild symbols appear stacked on the reels, meaning they take up multiple positions to increase payout potential.

The main feature is triggered by hitting 3 or more Scatters anywhere on the reels, which activates 10 free spins. More Scatter hits add additional spins. During free games, stacked wilds are more frequent to help create big wins.

100 Zombies also includes a classic Gamble feature. After any base game win, players can choose to try doubling their payout by selecting a random card that beats the dealer’s. This continues for up to 10 successful gambles, but failing at any point forfeits all winnings.

Volatility and Return to Player

100 Zombies has a stated RTP (return to player) of 96%, providing favorable odds for players over time. The hit frequency sits at around 25%, leading to a balanced number of payouts.

The slot volatility is classified as medium, meaning players can expect a healthy mix of smaller frequent wins and larger periodic payouts. The horror theme and bonus features provide regular entertainment even during dry spells.

Mobile Optimization

100 Zombies has been optimized by Endorphina for mobile and tablet gameplay. The graphics and features translate smoothly to smaller screens without sacrificing visual quality. Mobile users can enjoy the creepy world and smooth spinning experience on iOS and Android devices.

The gameplay is fully adapted for touchscreens, with simple gestures for changing bets, spinning reels, and accessing game options. Even in portrait mode, 100 Zombies looks great and plays flawlessly, making it a top mobile slot option.

100 Zombies Slot Experience

In our playthrough, stacked wilds appeared early on, leading to a few 20x wins. The free spins took a while to hit but proved rewarding with numerous retriggers, extending play. Several 200x wins occurred by reels filling with wild stacks.

While the max 10,000x win would require incredibly rare luck, the persistent stacked wilds and retriggering free spins brought consistent excitement and big payouts.

100 Zombies brings a graphically impressive zombie apocalypse to life across its 5×4 reel format. Stacked wilds drive bigger wins in the base game, while the free spins feature supplies a classic extra gameplay mode.

The medium volatility ensures spins stay lively, although the gameplay itself is quite typical of zombie slots. Fans of the genre should still find the presentation and playable features provide solid entertainment even if it breaks little new ground.

While the potential 10,000x win is enticing, stack wilds across all reels on every spin would be extremely hard to achieve. But with an above-average RTP and rewarding free spins, 100 Zombies succeeds at bringing zombie-bashing action to the reels.


With superb graphics and sounds that capture the zombie survival horror theme, 100 Zombies provides an immersive and entertaining gaming experience. The mix of features like stacked wilds, free spins, multipliers, and a Gamble option give players plenty to look forward to beyond just spin after spin. Endorphina has crafted an engaging slot that delivers frequency payouts and big reward potential in equal measure. For slot fans looking for surviving a different kind of scary and exciting adventure, 100 Zombies is a must-try.
