what we measured
| parameter | value |
|---|---|
| provider | Reel Kingdom (Pragmatic Play) |
| rtp default | 96.07% (simulated) |
| rtp versions on file | 96.07 |
| volatility | |
| hit frequency | estimated at 20% for a high-volatility game (provider does not publish one; low-confidence) |
| max win | 10,000x |
| mechanics | money-collect;hold-and-spin |
| simulated | 115,749,686 spins, 9 stake/bankroll cells, 2,000-spin cap |
These are simulation-based observations from a model calibrated to the published RTP. Hit frequency 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 2000 spins at $0.20 a spin, 1160 spins at $0.50, and 396 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 96.07% version, 95% CI):
| $50 bankroll | $100 bankroll | $200 bankroll | |
|---|---|---|---|
| $0.20/spin | 56.4% ±1.0 | 15.1% ±0.7 | 0.0% ±0.0 |
| $0.50/spin | 83.9% ±0.7 | 66.4% ±0.9 | 27.9% ±0.9 |
| $1.00/spin | 92.8% ±0.5 | 83.7% ±0.7 | 66.1% ±0.9 |
what a finished session looks like
At $0.50 on a $100 bankroll the median session ended with $0.38 of the original $100. The 90th percentile kept $265.01. 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 115,749,686 simulated spins, with 95% confidence intervals. Hit frequency is 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
1% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 95%.
A normal spin in our simulation never returned more than ~200x (€100). The 10,000x top win is a feature event, it only came out of the bonus. (base-game ceiling: paytable-sourced)
