100 Zombies is a Halloween-themed video slot from Endorphina with 100 paylines, low volatility and a published RTP of 96.03%. This review explains how the game is built, what its math profile means for your bankroll, and which safety points matter before you play for real money. A free demo is available on this site, so you can try the game first.
Gameplay and Theme
The game draws on horror imagery and a spooky Halloween atmosphere, placing zombies at the centre of the design. It is classed as a video slot, so expect animated symbols and a straightforward spin-and-match format.
With 100 paylines, wins can form across many line combinations on each spin, which tends to produce frequent small hits rather than rare large ones. Check the in-game paytable for the exact reel layout, symbol values and any special symbols or bonus rounds.
Math Profile: RTP, Volatility and Max Win
RTP
The official published RTP is 96.03%. This is a long-run theoretical average across a very large number of spins, not a prediction for a single session. Operators can offer different RTP versions of the same game, so confirm the figure in the in-game info screen.
Volatility and Bankroll
Volatility is low. Wins should land more often but are generally modest, which suits players who prefer longer sessions and steadier balance movement. Even so, a low-volatility slot can still lose money over a session, so set a budget before you start and size your stake so you can play comfortably through losing stretches.
Max Win
The maximum win is 5,000x the stake. That is a ceiling reached only in rare circumstances, and low-volatility games usually deliver results well below it. Treat it as an upper limit rather than an expectation.
Fairness and Player Safety
Licensed online slots rely on a random number generator to determine every spin outcome. Independent testing labs such as eCOGRA, iTech Labs and BMM Testlabs typically test RNG behaviour, check that payouts match the stated RTP, and review game integrity. Their reports help regulators and operators confirm that games behave as designed.
Before depositing, verify the casino holds a valid licence from a recognised regulator such as the MGA or UKGC. The licence details are normally shown in the site footer and can be checked on the regulator's public register.
Gambling is for adults aged 18 or over. Use deposit and time limits, never chase losses, and play only with money you can afford to lose. If gambling stops being fun, organisations such as BeGambleAware offer free support.
