About the game

What the game actually does — read in the game, not in the press release

Endorphina and 100 Zombies listed among titles with Free Spins (released 20 Oct 2020)

Endorphina lists this title among its slots that feature Free Spins. The release date is 20.10.2020 and the game’s declared mechanics include Scatter, Wild, Free Spins and a Risk/Gamble function.

This places 100 Zombies in the provider’s catalogue as a standard slot with bonus rounds; no additional systems are indicated beyond the mechanics Endorphina has published.

How Free Spins and Scatter symbols determine a round

Free Spins are listed as a core mechanic and are typically triggered by Scatter symbols, which is consistent with the game’s listed features. When the required number of Scatters appears, the Free Spins round starts according to the game rules as published.

A single spin resolves by the reels spinning and any payout being calculated according to the game’s pay structure, with Wilds substituting for other symbols where allowed and Scatters activating Free Spins.

RTP 96% while volatility is not provided

The game states a theoretical return to player of 96 %. This is the only long‑term expectation figure published — volatility is not provided in the data.

The absence of a volatility rating means there is no supplier‑given indication of how often or how large wins are likely to occur; RTP alone does not describe session variance.

Max win 10,000x — what that implies for the rest of the machine

Endorphina publishes a max win of 10,000x the stake, which sets a firm upper limit on what a session can deliver in theory. When a machine carries such a cap, it constrains the combination of multipliers and payouts in both bonus rounds and the base game.

Having a published max win is helpful, but it does not indicate the likelihood of achieving it; combined with a 96% RTP and no volatility data, the picture of large‑win frequency remains incomplete.

Who 100 Zombies is likely suited for — and who should look elsewhere

Players who prefer slots with Free Spins and a known cap (10,000x) will find the game straightforward in terms of limits. Players who require an explicit volatility rating to plan their stake strategy will not find that information here.

Those who want clearly quantified features get some answers (RTP, max win), but those seeking detailed variance data or specifics about the Risk/Gamble mechanic should be aware the published sources do not provide them.

Rules

Base game

The provider does not publish information about the reel layout or number of paylines/ways for this game. The game's concrete layout is shown in the game interface at the operator.

Wins are formed according to the game's rules and paytable. The specific combinations that pay and which positions count as winning must be checked in the game's paytable.

Wild

The game lists wild symbols. Mechanically, wilds affect wins by substituting for other symbols in winning combinations.

Endorphina has not published further details in the DATA about which symbols the wild can substitute for or any special rules tied to wilds.

Scatter

The game lists scatter symbols. Mechanically, scatters are used for special payouts or to trigger bonus features independently of line position.

The DATA contains no details about how many scatters are required for a payout or bonus, or whether scatters pay directly in this game.

Free Spins

Free Spins are listed as a mechanic. Mechanically, this means there are rounds of free spins that the player can win or trigger.

The provider has not published in the DATA how free spins are triggered, how many spins are awarded, or any special rules during free spins in this game.

Risk/Gamble (Double) game

The game includes a risk/gamble feature (double) where the player can mechanically attempt to increase a payout by wagering the win amount.

The DATA does not include details on the gamble mechanics, such as odds, limits, or which wins may be gambled.

RTP and volatility

The listed return-to-player (RTP) is 96 %. This indicates the theoretical portion of stakes the game returns to players over time as stated by the provider.

Volatility is not published for this game in the DATA. This means the provider has not given a formal description of payout frequency or variance for the game.

Maximum win

The provider states a maximum win of 10 000x the stake.

No further details on how this maximum is achieved are published in the DATA.

Verdict

What earns your time and what does not

Pros

RTP stated as 96%.
Max win clearly listed as 10,000x stake.
Includes Wild, Scatter and Free Spins in the listed mechanics.

Cons

Volatility is not published in the available data.
No details provided about how the Risk/Gamble feature operates.
Number of Scatters required for Free Spins is not specified in the sources.

100 Zombies delivers clear published figures for RTP and max win but lacks volatility and Gamble‑feature details. If you need full technical transparency, the available information is incomplete.
