We simulated Sweet Bonanza across nine stake/bankroll combinations at the 96.48% provider default, 10,000 sessions each, then re-ran the full grid at the 94.50% floor version (187,009,517 simulated spins in total). At $0.50 a spin against a $100 bankroll, 77.7% ±0.8 of sessions busted before the 2,000-spin cap and the median session ended with $0.33. The published RTP ladder for this game spans 1.98pp, and the floor version raised the bust rate in every cell we measured. Bonus frequency and average bonus value are modelled estimates; the absolute bust levels inherit that uncertainty, the version-lottery delta does not.

These results are simulation-based observations from a model calibrated to the published RTP. Hit frequency and, where applicable, bonus frequency and value are estimates and are flagged above; absolute bust levels carry that uncertainty, while the default-versus-floor comparison holds those inputs constant and so is robust.

how long bankrolls survived

survival curves, share of sessions still alive vs spins played

At a $100 bankroll, the median session lasted 2000 spins at $0.20 a spin, 595 spins at $0.50, and 212 spins at $1.00. Stake-to-bankroll cover, not the game, decided how long the money lasted: every step up in stake at a fixed bankroll shortened the session and raised the chance of busting.

what a finished session looks like

final bankroll by percentile

At $0.50 on a $100 bankroll the median session ended with $0.33 of the original $100. The 90th percentile kept $334.05. In our model a bonus arrived about once every 201 spins on average (a modelled trigger rate, flagged). This is the shape of a negative-expectation game: most sessions drain toward zero, a few tails run long, and the average is propped up by outcomes most players never see.

the rtp version lottery

The same game ships at different RTP versions and the casino chooses which to run. We re-ran the full grid at the 94.50% floor. Holding every other input constant, only the RTP changed:

cell96.48% default94.50% floordelta
$0.20 / $10040.5%43.7%+3.3pp
$0.50 / $10077.7%79.5%+1.8pp
$0.50 / $20052.7%56.4%+3.7pp
$1.00 / $20077.9%80.3%+2.4pp

Same game, same animations, same bonus wait. The difference is which version the operator licensed, the one variable a player never sees on the reels. This is why we promote the casino running the highest published version: see the casinos ranked by verified RTP.

methodology note

We simulate models calibrated to published math (RTP, hit frequency, volatility class, bonus behaviour), not the provider's game engine. Results are sample-based observations from 187,009,517 simulated spins across two RTP calibrations, with 95% confidence intervals. Estimated for a pragmatic tumble engine (pragmatic does not publish a hit frequency for this title; low-confidence). Bonus frequency and average bonus value are modelled estimates; the absolute bust levels inherit that uncertainty, the version-lottery delta does not. Slots are negative-expectation games; nothing here predicts outcomes or improves odds. Corrections policy: methodology.html.

Where the max win actually comes from

base 41%
feature 55%

57% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 41%.

A normal spin in our simulation never returned more than ~5,056x (€2,528). The 21,100x top win is a feature event, it only came out of the bonus. (base-game ceiling: model estimate)

FAQ

Is there a Sweet Bonanza demo or free play?

Yes. You can play Sweet Bonanza 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 Sweet Bonanza worth playing?

It is negative-expectation like every slot. In our simulation, 77.7% of $0.50/$100 sessions busted before the 2,000-spin cap. We report the cost; we never tell you to play.
