what we measured
| parameter | value |
|---|---|
| provider | Pragmatic Play |
| rtp default | 96.50% (simulated) |
| rtp versions on file | 96.50 |
| volatility | high (5/5) |
| hit frequency | estimated at 17% for a extreme-volatility game (provider does not publish one; low-confidence) |
| max win | 5,000x |
| mechanics | scatter-pays;tumble;multiplier;bonus-buy |
| simulated | 81,130,773 spins, 9 stake/bankroll cells, 2,000-spin cap |
These are simulation-based observations from a model calibrated to the published RTP. Hit frequency and bonus frequency/value are estimates, flagged above; absolute bust levels carry that uncertainty, while the default-versus-floor comparison holds those inputs constant.
how long bankrolls survived
At a $100 bankroll, the median session lasted 1617 spins at $0.20 a spin, 400 spins at $0.50, and 152 spins at $1.00. Stake-to-bankroll cover, not the game, decided how long the money lasted.
bust rates
Share of sessions that busted before the 2,000-spin cap (default 96.50% version, 95% CI):
| $50 bankroll | $100 bankroll | $200 bankroll | |
|---|---|---|---|
| $0.20/spin | 79.5% ±0.8 | 56.6% ±1.0 | 13.9% ±0.7 |
| $0.50/spin | 92.2% ±0.5 | 83.3% ±0.7 | 64.9% ±0.9 |
| $1.00/spin | 95.9% ±0.4 | 92.2% ±0.5 | 83.9% ±0.7 |
what a finished session looks like
At $0.50 on a $100 bankroll the median session ended with $0.31 of the original $100. The 90th percentile kept $315.43. In our model a bonus arrived about once every 332 spins on average (a modelled trigger rate, flagged). Most sessions drain toward zero while a few tails run long, which is what negative expectation looks like over many sessions.
methodology note
We simulate models calibrated to published math, not the provider's game engine. Results are sample-based observations from 81,130,773 simulated spins, with 95% confidence intervals. Hit frequency and bonus parameters are estimated and flagged. Slots are negative-expectation games; nothing here predicts outcomes or improves odds. Corrections policy: methodology.html.
Where the max win actually comes from
62% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 36%.
On this slot the big multipliers live in the base game too, so the max win can land on a normal spin, just extremely rarely (our biggest normal spin reached ~5,000x). The feature is still where it usually happens. (base-game ceiling: model estimate)
