100 Zombies

What is 100 Zombies?

100 Zombies is a low-volatility online slot from Endorphina set in a zombie apocalypse. It operates on a 5×4 grid with 100 fixed paylines, featuring Stacked Wilds and a Free Spins bonus round. The game's mathematical model is defined by a Return to Player (RTP) of 96.03%, which offers a fair rate of return over extended play. Its low volatility translates to a gameplay experience characterized by frequent, smaller wins that help maintain a player's balance while hunting for the more lucrative bonus features.

How to Win in 100 Zombies

Wins are achieved by landing matching symbols on any of the 100 paylines, starting from the leftmost reel. The key to larger payouts lies in the high-value character symbols and the frequent appearance of Stacked Wilds. The game's structure, with its large number of paylines, means that multi-line wins from a single spin are common, especially when wild symbols are involved.

What is the role of Stacked Wilds?

Stacked Wilds can appear on any reel during both the base game and free spins, potentially covering the entire reel. This mechanic is crucial for creating multiple winning combinations across the 100 paylines in a single spin. The Wild symbol, represented by a vault, substitutes for all other paying symbols except the Scatter. A full reel of wilds acts as a powerful bridge, connecting symbol combinations that would otherwise not result in a win.

Understanding Character and Symbol Payouts

The paytable is divided into zombie hunters, zombies, and card royals. The ‘grumpy man' hunter and the baseball cap zombie offer the highest regular payouts, while the Wild symbol provides the single largest line win. The three hunters—an old man, a young man, and a woman—represent the high-tier symbols, followed by three distinct zombie characters as mid-tier payers. The classic A, K, Q, and J symbols make up the low-tier payouts. Landing five Wild symbols on a payline awards 10x the total bet, the highest prize for a single line.

Are the Bonus Features Worth Targeting?

Yes, the primary bonus feature—Free Spins with Stacked Wilds—is the main source of high win potential. The optional Risk Game and Bonus Pop features offer shortcuts but come with increased risk and lower RTP. While the base game provides steady action, the financial core of the slot is firmly located in its bonus round, making the Scatter symbol your most important target.

How does the Free Spins feature work?

The feature is triggered by landing three Scatter symbols on reels 2, 3, and 4, awarding 10 free spins. During these spins, Stacked Wilds appear more frequently, significantly boosting the potential for full-screen wins. The Scatter symbol, designed as a biohazard sign, is the only symbol that cannot be substituted by the Wild. The feature can be retriggered by landing three more Scatters during the bonus round, adding another 10 spins to the remaining total. This retriggering capability is key to achieving the game's maximum win potential.

The Risk Game: A Good Bet or a Trap?

It's generally a trap for significant wins due to its low 84% RTP. This classic ‘beat the dealer' card game allows you to double a win up to 10 times, but it's mathematically unfavorable for the player over time. After any win, you have the option to risk it by choosing one of four face-down cards. If your card is higher than the dealer's, your win is doubled. While tempting for small amounts, risking substantial wins is not a recommended strategy.

What Is the Bonus Pop Feature?

Bonus Pop is a feature buy option that allows players to purchase direct entry into the 10 Free Spins round for a set price. However, using this feature reduces the game's overall RTP from 96.03% to 94.61%. This trade-off between immediate access to the bonus and a lower theoretical return is a strategic choice for the player. While it provides instant access to the game's most exciting phase, it comes at a mathematical cost.

How to Play 100 Zombies Demo

To play the demo, first set your bet amount using the coin value and line options. Then, simply press the spin button to start the game or use the autoplay feature for a continuous session. The interface is user-friendly, with controls for adjusting your stake, activating turbo spin for faster rounds, and accessing the paytable information. The game accommodates a wide range of budgets, with bets ranging from €1.00 to €200.00 per spin when all 100 lines are active.

Achieving the Best Results in 100 Zombies

Maximizing results involves managing your bankroll to withstand the wait for the Free Spins feature, as this is where the highest win potential is concentrated. Avoid overuse of the low-RTP Risk Game and Bonus Pop features. A sound strategy is to set a bet level that allows for at least 150-200 spins, giving you a reasonable chance to trigger the bonus round organically. The low volatility helps in this regard, as frequent small wins will often replenish your balance during the base game.

Vlad Hvalov advises: The 84% RTP on the Risk Game is a statistical trap. Use it sparingly on minor wins for a quick thrill, but never risk a significant payout. The math is heavily against you in the long run.
