100 Zombies

100 Zombies: A Horror Slot by Endorphina

Game Theme and Visual Design

Endorphina has fully committed to the zombie apocalypse theme in this slot. The game is set against a grim, desolate cityscape, with crumbling buildings and a blood-red sky setting a perfectly ominous tone. The reels themselves are framed within a rusted, industrial-looking border, adding to the sense of decay and despair. The visual design is detailed and atmospheric, with high-quality graphics that bring the horror to life. Every symbol, from the low-paying card suits to the terrifying zombie characters, is meticulously crafted. The audio design completes the experience, featuring a suspenseful, cinematic soundtrack punctuated by groans, distant screams, and the chilling sound of dragging feet. This atmospheric combination ensures that every spin in 100 Zombies feels like a step deeper into a dangerous, undead-infested zone.

Symbols, Paylines, and Betting Range

100 Zombies operates on a fixed payline structure, meaning all ways to win are active on every spin. This simplifies the betting process and ensures you never miss a winning combination due to an inactive line. The symbols are a mix of classic horror icons and thematic high-value images. The lower-paying symbols are the familiar 10, J, Q, K, and A, styled with a grungy, infected aesthetic. The higher-paying symbols are the zombies themselves—a terrifying cast of undead characters including a hazmat suit zombie, a soldier zombie, and more. The top-paying symbols are the man with the bat and the fat zombie, each awarding 6x the base bet for five of a kind. The game's wild symbol substitutes for all other symbols except the scatter and can appear stacked on the reels. With a min bet of 1 and a max bet of 200, 100 Zombies offers a betting range that suits a variety of strategies.

Special Features and Bonus Rounds

The true terror—and potential treasure—of 100 Zombies lies in its special features. The game is packed with mechanics designed to trigger big wins and improve the gameplay beyond a standard spin.

• Scatter Symbol & Free Games: The game's scatter is the biological hazard symbol, and landing three triggers 10 free spins. Landing three or more scatter symbols anywhere on the reels triggers the Free Games feature. The number of free spins awarded typically depends on the number of scatters landed, offering a chance for extended play without placing additional bets.


• Risk (Gamble) Game: A hallmark of Endorphina slots, the Risk Game allows you to gamble any win. After a winning spin, you can choose to enter this double-or-nothing round. You'll be presented with a facedown card and must guess if the next card will be higher. A correct guess doubles your win, while a wrong guess loses it all. This feature can be played repeatedly, adding a massive layer of risk and potential reward.


• Bonus Features: 100 Zombies often includes unique bonus mechanics, such as expanding wilds, sticky symbols, or multiplier features during the free spins round. These can dramatically increase the win potential during the bonus, turning a modest free games session into a legendary survival payout.

Volatility, RTP, and Max Win Potential

This means wins may not land on every spin, but when they do, they have the potential to be substantial. This type of gameplay is ideal for players with larger balances who enjoy the thrill of the chase and are prepared for potential dry spells in anticipation of a major payout. Although the exact RTP (Return to Player) percentage for 100 Zombies is not commonly published, Endorphina's portfolio generally features RTPs around the industry average. The maximum win potential is a key attraction, often reaching several thousand times your stake.
