Zombie Blasters at 389win: a cascading scatter-pays slot
Zombie Blasters is a PG Soft slot on a 6-reel, 5-row grid that pays by scatter: there are no paylines, and a win lands whenever 8 or more matching symbols appear anywhere on screen. Winning symbols are removed and new ones drop in — cascades, or tumbling wins — so one stake can produce a chain of payouts. Our sources list a 96.75% RTP, high volatility and a 10,000x maximum win. It is one of the two titles in the 389win lobby that we could review with verified data.

Scatter pays: count, not position
On a payline slot, where a symbol lands matters; here only the count does. Eight identical symbols scattered across the 30 positions form a win, and larger clusters pay more — the exact paytable sits in the game's info panel. That design produces frequent empty spins and, now and then, a screen dominated by one symbol, which is a big part of why the game is classed as high volatility.
Cascades in practice
After a win, the winning symbols vanish, the remaining ones fall, and fresh symbols fill the top. If the new layout holds another group of eight or more, it pays again, and the chain continues until no group remains. Cascades do not raise the RTP; they change how the return is delivered — in bursts rather than a steady trickle.
What 96.75% RTP means for a session
RTP is a long-run average over millions of rounds: for every 100 units wagered, 96.75 return on average, so the expected cost is 3.25 units per 100. Any real session can land far above or below that. Some slots ship with several RTP configurations, so confirm the figure shown in the info panel for your account.
Bankroll and stake size
| Bankroll | Stake per spin | Spins available | Expected cost |
|---|---|---|---|
| 100 units | 0.50 | 200 | 3.25 |
| 100 units | 2.00 | 50 | 3.25 |
| 100 units | 5.00 | 20 | 3.25 |
Illustrative example, not a 389win term. Expected cost is identical because total turnover is identical. What changes is the experience: 20 spins often end before any decent cascade; 200 give the game more chances to show its upside. On a high-volatility slot, smaller stakes stretch the session without changing the maths.
The 10,000x ceiling in perspective
The cap defines how far a single round can go — 5,000 units on a 0.50 stake. Illustrative example, not a 389win term. It is an extremely rare event and should never be a session target. Its existence explains why most rounds pay little: the return has to "save room" for occasional huge hits.
Clearing wagering on Zombie Blasters
A 96.75% RTP makes the game comparatively cheap for wagering: 3,000 units of turnover cost about 97.5 units on average, versus 179.1 on a 94.03% slot. High volatility, however, raises the chance of busting before you finish. Check that the game contributes 100% to your offer and respect the max bet. Full method: wagering.
