Play 100 Zombies Demo Inside This Review

What Defines 100 Zombies?
100 Zombies looks like a horror slot on the surface, but the useful read starts with the 5x4 layout and 100-line model. The theme is loud; the rules are where the page earns or loses trust.
How In-Game Free Spins Works in 100 Zombies
Endorphina lists 5 mechanics for 100 Zombies: Wild, Risk Game, Bonus Pop, In-Game Free Spins and Scatter. Free Spins is the feature to follow first. Risk Game deserves its own check because it can risk a result already won.
Wild in 100 Zombies
Wild can help connect the 100-line paytable, but the help screen decides the exact placement rules. Check excluded symbols, eligible reels and whether Wild wins can enter Risk Game.
Risk Game in 100 Zombies
Risk Game does not improve the next spin. It risks a win you already have. Find the collect button, loss condition and stopping point in demo mode first.
Bonus Pop in 100 Zombies
Bonus Pop should be checked in the win history. Note what changes on the grid, which symbols are affected and whether the result still settles through 100 lines.
In-Game Free Spins in 100 Zombies
Free Spins should be watched from trigger to reset. Check the qualifying symbols, starting spin count, retriggers and whether Wild or Bonus Pop changes during the sequence.
Scatter in 100 Zombies
Scatter is verified as part of 100 Zombies, but its full rule belongs to the loaded help screen. Record where it appears on the 5x4 format and whether the result is settled through 100 or a separate mode.
100 Zombies Base Game Before Free Spins
100 Zombies uses a 5x4 board with 20 visible symbol spots. Endorphina lists 100 lines. A match needs the right line, direction and symbol count from the paytable.
The published range is 1 EUR to 200 EUR. One hundred spins cost 100 EUR at the floor and 20,000 EUR at the top before returns. That 1 EUR minimum makes careless testing expensive quickly.

100 Zombies Symbols: SCATTER and the Paytable

| Symbol | Documented role | Public payout note |
|---|---|---|
| SCATTER | Bonus or feature-trigger symbol | Up to 2x the base bet in the described combination |
| WILD | Wild or substituting symbol | See the complete in-game paytable |
| TOP PAYING SYMBOL | Higher-value paying symbol | Up to 6x the base bet in the described combination |
| OTHER SYMBOL | Regular paying symbol | Up to 6x the base bet in the described combination |
The public page lists the top paying symbol at up to 6x the base bet, with another symbol example also at 6x. Those examples are modest, so the full paytable matters more than the headline artwork.
96.03% RTP and Low Volatility
Endorphina publishes 96.03% RTP for the reviewed 100 Zombies configuration. Subtracting that value from 100 gives an approximate 3.97% theoretical edge; the number describes aggregated rounds rather than the balance path produced by a single In-Game Free Spins trigger.
Low volatility suggests a less spiky model than high-volatility slots, but short sessions can still lose. Keep the 1 EUR to 200 EUR range near the floor while checking 100 lines and Free Spins.
A Focused 100 Zombies Demo Test
- Open the help screen and confirm 96.03% RTP, low volatility and the 1 EUR to 200 EUR interval.
- Run a fixed-stake demo and sample the 100 lines on the 5x4 board.
- Track Scatter from landing to feature entry or payout.
- Watch one Free Spins sequence without changing stake.
- Check Wild and Bonus Pop in result history.
- Use Risk Game once after a small demo win, then collect.
Who Is 100 Zombies Best Suited To?
100 Zombies fits players who want a horror-themed 5x4 slot with many lines and a lower volatility label. I would avoid it for casual tiny-bankroll testing, because the 1 EUR minimum is not tiny.

100 Zombies is a 5x4 slot with 100 lines, 96.03% RTP, low volatility, Wild, Risk Game, Bonus Pop and Free Spins. The public page still skips the maximum-win cap. That missing number belongs in the live casino help screen.
100 Zombies Sources and Verification
Game specs, feature labels, symbol examples and artwork were checked on the official Endorphina page for 100 Zombies. The page does not publish a maximum win or full static paytable, so this review leaves those values unclaimed and points readers back to the loaded rules.
