what we measured
| parameter | value |
|---|---|
| provider / engine | Push Gaming · cluster pays, cascading rainbows, gold-vinyl progression |
| rtp simulated | 96.40% (published headline; operator versions ~95.35% / 94.40% reported single-source only) |
| volatility | high |
| stakes | $0.20 / $0.50 / $1.00 per spin |
| bankrolls | $50 / $100 / $200 |
| sessions | 10,000 per stake/bankroll cell, 90,000 total |
| spin cap | 2,000 spins per session |
| max win | 50,000x stake (a feature event) |
model inputs worth flagging: the 96.40% RTP and the 50,000x max are sourced. the in-game "gold vinyl" progression that nudges RTP between roughly 96.1% and 96.6% is a session mechanic, not an operator-selectable version, so we do not treat it as a ladder; the lower operator versions (~95.35% / 94.40%) are single-source and not simulated. Push does not publish a hit frequency or bonus trigger rate, so both were modelled (about 24% hit, one feature every ~202 spins) as documented assumptions; the bonus payout distribution and the ~300x base-game ceiling are model assumptions calibrated to the published RTP and the 50,000x cap.
how long bankrolls survived
the stake sets the clock. at the $100 bankroll the median session ran 777 spins at $0.50. the cluster mechanic keeps small cascades coming, but the rainbow feature is where the big multipliers build, and most bankrolls run dry before a real one lands.
bust rates
bust rates within the 2,000-spin cap, 96.40% version, 95% confidence intervals:
| $50 bankroll | $100 | $200 | |
|---|---|---|---|
| $0.20/spin | 66.8% ±0.9 | 32.0% ±0.9 | 0.6% ±0.1 |
| $0.50/spin | 87.4% ±0.7 | 74.0% ±0.9 | 45.4% ±1.0 |
| $1.00/spin | 93.7% ±0.5 | 87.7% ±0.6 | 74.8% ±0.9 |
plain reading: hold the bankroll at $100 and move the stake from $0.20 to $0.50, and the bust rate more than doubles from 32.0% to 74.0%. the only safe cell is $0.20 against $200 (0.6%).
the bonus wait, and what it pays
on our modelled trigger rate (about 1 in 202 spins, an assumption), the feature carries about 47% of the total return. the payout side (model-based estimates): the average feature paid 90x stake but the median was 49x, and 51% paid under 50x. the 50,000x ceiling is the rare tail; a typical feature pays around half the average.
what a finished session looks like
the final-bankroll distribution at $0.50/$100 has almost no middle. seven sessions in ten ended with under $0.50 of the original $100, busted, in effect, with the median finish near $0.35. then it leaps: the 90th percentile kept $305. the same die-or-detonate shape as the rest of our library.
on the version question
most of our studies close with the cost of the casino's RTP version choice. for jammin' jars 2 we don't simulate one: the 96.40% headline is solid, but the lower operator versions reported for this title come from single sources, so publishing a "floor" would mean inventing a number. the general rule still holds, check the published RTP of the exact version at your casino and play it where that number is highest. our casino hub ranks operators by exactly that. (this is jammin' jars 2, a separate game from the 2018 original.)
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 102,060,694 simulated spins (90,000 sessions), with 95% confidence intervals shown. we simulated the 96.40% published version; lower operator versions are single-source and not modelled, and the gold-vinyl progression is a session mechanic, not a casino ladder. hit frequency and bonus trigger rate are not published and were modelled as documented assumptions; the bonus payout distribution and the ~300x base-game ceiling are reasoned estimates, not sourced. the 50,000x max is a feature event. model validation: jammin-jars-2 v1, analytic calibration exact at 96.40%, 10M-spin check 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
47% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 51%.
A normal spin in our simulation never returned more than ~300x (€150). The 50,000x top win is a feature event, it only came out of the bonus. (base-game ceiling: model estimate)
