Run it yourself in the live simulator. All figures are simulation-based observations, not predictions. See our methodology.
what we measured
| parameter | value |
|---|---|
| provider | Games Global (Microgaming) |
| rtp default | 88.12% (simulated) |
| rtp versions on file | 88.12 |
| volatility | medium (slotcatalog) |
| hit frequency | estimated at 24% for a medium-volatility game (provider does not publish one; low-confidence) |
| max win | 11,250x |
| mechanics | progressive-jackpot;free-spins |
| simulated | 105,030,050 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 2000 spins at $0.20 a spin, 867 spins at $0.50, and 337 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 88.12% version, 95% CI):
| $50 bankroll | $100 bankroll | $200 bankroll | |
|---|---|---|---|
| $0.20/spin | 72.0% ±0.9 | 26.2% ±0.9 | 0.0% ±0.0 |
| $0.50/spin | 91.8% ±0.5 | 79.8% ±0.8 | 46.4% ±1.0 |
| $1.00/spin | 96.7% ±0.4 | 92.2% ±0.5 | 80.5% ±0.8 |
what a finished session looks like
At $0.50 on a $100 bankroll the median session ended with $0.33 of the original $100. The 90th percentile kept $132.05. In our model a bonus arrived about once every 252 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 105,030,050 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
27% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 64%.
A normal spin in our simulation never returned more than ~600x (€300). The 11,250x top win is a feature event, it only came out of the bonus. (base-game ceiling: paytable-sourced)

FAQ
What is the real RTP of mega moolah?
The default published RTP we modelled is 88.12%. Check the RTP in the game's info panel at your casino, versions can differ.
Is mega moolah a tight slot? How many sessions bust?
In our simulation at the default RTP, 79.8% of $0.50-a-spin sessions on a $100 bankroll busted before the 2,000-spin cap. That is a measured session cost across thousands of simulated sessions, not a prediction for your next one.
How often does the mega moolah bonus hit?
About once every 248 spins on average in our simulation, roughly 50 minutes at five spins a minute. Real gaps vary widely around that average, and a bonus is never "due".
Is there a mega moolah demo or free play?
Yes. You can play mega moolah in demo mode at most casinos, and you can stress-test it free in our simulator, which runs thousands of sessions and reports the bust rate and session length, the demo with the math switched on.
Is mega moolah worth playing?
It is negative-expectation like every slot. In our simulation, 79.8% of $0.50/$100 sessions busted before the 2,000-spin cap. We report the cost; we never tell you to play.
