what we measured
| parameter | value |
|---|---|
| provider / engine | Games Global · 9 paylines, free spins with 3x multiplier |
| configs simulated | 96.24% (provider default) · 92.01% (floor of the published ladder) |
| published rtp ladder | 96.24% / 94.06% / 92.01%, a verified 4.23pp spread the casino selects |
| volatility | medium |
| hit frequency | 39.75% (provider-cited) |
| stakes | $0.20 / $0.50 / $1.00 per spin |
| bankrolls | $50 / $100 / $200 |
| sessions | 10,000 per stake/bankroll cell, 90,000 per version |
| spin cap | 2,000 spins per session |
| max win | 2,000x base; up to 6,000x via the free-spins 3x multiplier |
model inputs worth flagging: the RTP ladder, hit frequency (39.75%) and the max win are sourced. the bonus trigger rate is not provider-published, so we modelled it (about one free-spins round every ~100 spins) as a documented assumption; the bonus payout distribution and base-versus-feature split are model assumptions calibrated to the published RTP and the 6,000x cap. the cross-version comparison holds all inputs constant, so it is robust; absolute bonus figures are estimates.
how long bankrolls survived
the stake sets the clock, and 9 masks is kind to it: at the $100 bankroll the median session ran 1,576 spins at $0.50, among the longest in our library, because the high hit rate and frequent bonus keep money cycling. survivable, but still not a winning game.
bust rates
bust rates within the 2,000-spin cap, 96.24% default version, 95% confidence intervals:
| $50 bankroll | $100 | $200 | |
|---|---|---|---|
| $0.20/spin | 46.3% ±1.0 | 6.4% ±0.5 | 0.0% ±0.0 |
| $0.50/spin | 79.8% ±0.8 | 57.9% ±1.0 | 17.1% ±0.7 |
| $1.00/spin | 91.2% ±0.6 | 80.1% ±0.8 | 57.4% ±1.0 |
plain reading: like the gentler classics, a low stake on a healthy bankroll is genuinely safe here, $0.20 against $100 busted only 6.4%. but push the stake to $0.50 and the majority still bust, and at $1.00 it behaves like the rest of the library.
the bonus wait, and what it pays
on our modelled trigger rate (about 1 in 100 spins, an assumption), the bonus is frequent. the payout side (model-based estimates): the average bonus paid 35x stake and the median just 19x, with 81% paying under 50x. 9 masks spreads its return across many small bonuses rather than rare big ones, which is why sessions last so long.
what a finished session looks like
9 masks has more of a middle than most of our library: at $0.50/$100 the median session ended around $23 of the original $100, with the 70th percentile near $85 and the 80th around $147. more sessions limp to the cap with something left than on a high-volatility game, but the majority still reach zero, and the floor version pushes more of them there.
the rtp version lottery
9 masks of fire is published at 96.24% and also at 94.06% and 92.01%, a 4.23-point spread the casino selects. we ran the full grid at the default and the floor; same model, same inputs, only the RTP changed:
| cell | 96.24% default | 92.01% floor | delta |
|---|---|---|---|
| $0.20/$100 bust | 6.4% ±0.5 | 13.4% ±0.7 | +7.1pp |
| $0.50/$100 bust | 57.9% ±1.0 | 69.6% ±0.9 | +11.8pp |
| $0.50/$200 bust | 17.1% ±0.7 | 28.8% ±0.9 | +11.7pp |
| $1.00/$200 bust | 57.4% ±1.0 | 69.4% ±0.9 | +12.0pp |
the floor version raised the bust rate by 7 to 12 points depending on the cell, a larger effect than the spread alone suggests, because on a lower-volatility game a couple of RTP points bite harder into the steady drip that keeps sessions alive. same game, same masks. the only difference is the RTP the operator chose to run. the version is the one variable a player can actually pick, so play it where the published RTP is highest. our casino hub ranks operators by exactly that.
methodology note
we simulate models calibrated to published math, RTP, hit frequency, volatility profile, bonus behaviour, not the provider's game engine. results are sample-based observations from 241,271,031 simulated spins (180,000 sessions across two RTP versions), with 95% confidence intervals shown. hit frequency (39.75%) is provider-cited; the bonus trigger frequency is not published and was modelled (~1 in 100) as a documented assumption; the bonus payout distribution and base-versus-feature split are modelled. the base-game ceiling (200x) is a reasoned estimate; the 6,000x max is reached via the free-spins multiplier. casino-by-casino RTP figures are the published ladder, not statements about any operator's current configuration. model validation: 9-masks-of-fire v1, analytic calibration exact at 96.24% and 92.01%, 10M-spin checks within tolerance. slots are negative-expectation games; nothing here predicts outcomes or improves odds. corrections policy: methodology.html.
Where the max win actually comes from
36% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 61%.
A normal spin in our simulation never returned more than ~200x (€100). The 6,000x top win is a feature event, it only came out of the bonus. (base-game ceiling: model estimate)
