What these numbers mean

An RTP of 96.00% means a house edge of 4.00% — the expected cost is 4.00 units per 100 staked over the long run, whatever a single session does.

The advertised ceiling is x100 000. Max win figures describe the tail of the distribution, not a realistic target: on most games with a ceiling this high the probability per spin is below one in a million.

Against our catalogue the number is below the median of 96.13%, higher than 28% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.

Stakes and layout

Stakes run from 0.2 to 1000 per spin on a 5 layout with fixed betways.

Frequently asked

What is the RTP of 100 Zombies?

100 Zombies has a published RTP of 96.00%, a house edge of 4.00%. We have not yet found a casino serving it at a different RTP build.

Can I play 100 Zombies for free?

Yes. 100 Zombies has a free demo with the same mathematics as the real-money version — the only thing that changes is that the balance is not yours. A demo cannot tell you the RTP build a particular casino serves.

Is 100 Zombies rigged?

100 Zombies is a Endorphina game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves. That is the real variable, and it is measurable.
