sugar rush hits often, a returning win lands roughly one spin in three (34.48% hit frequency), which makes it feel generous. we simulated 172,889,000 spins (90,000 sessions per version) across its published 96.50% default and its 94.50% floor version to see what that constant trickle actually does to a bankroll. at $0.50 a spin against a $100 bankroll, 82.0% of sessions still busted before the 2,000-spin cap on the default version, and the median session ended with about $0.43 of the original $100. the frequent small wins do not keep you alive; they slow the bleed just enough to keep you spinning while a high-volatility maths model empties the bankroll.

model inputs worth flagging: RTP (96.50%, three sources including Pragmatic's own page), the full ladder, hit frequency (34.48%), max win (5,000x) and free-spins trigger rate (1 in 323) are sourced; the bonus payout distribution and the base-versus-feature RTP split are model assumptions (lognormal calibrated to the published RTP and the 5,000x cap), so all bonus-value figures are model-based estimates. the base-game ceiling (500x) is a reasoned estimate, the 5,000x max is realistically a free-spins event because the multiplier spots reset every paid base spin.

how long bankrolls survived

survival curves, share of sessions still alive vs spins played

the stake sets the clock. at the $100 bankroll on the default version, the median session lasted 481 spins at $0.50 and far longer at $0.20. the high hit rate stretches sessions out, money keeps coming back in small amounts, but it does not change the destination: $0.50 against $50 busted 91.3% of the time, and even $1.00 against a deep $200 bankroll busted 81.4%.

bust rates

bust-rate grid, share of sessions that busted before the spin cap

bust rates within the 2,000-spin cap, default 96.50% version, 95% confidence intervals:

$50 bankroll$100$200
$0.20/spin76.5% ±0.849.3% ±1.06.4% ±0.5
$0.50/spin91.3% ±0.582.0% ±0.860.2% ±1.0
$1.00/spin95.3% ±0.491.3% ±0.581.4% ±0.8

plain reading: a game that pays this often still empties most bankrolls. hold the bankroll at $100 and move the stake from $0.20 to $0.50 and the bust rate jumps from 49.3% to 82.0%, the biggest lever in the grid. the only comfortable cell is $0.20 against $200 (6.4%). dead streaks were shorter than on classic line games, at $0.50/$100 the 90th-percentile worst winless run was 18 spins, which is exactly why the bleed is easy to miss: you rarely go long without something landing, but the somethings are too small to matter.

the bonus wait, and what it pays

the free-spins round triggered about once every 324 spins, matching the published 1-in-323 rate. the payout side (model-based estimates, pooled over the simulated bonuses): the average bonus paid 179x stake, but the median was 97x, half of all bonuses paid less than that, and 27% paid under 50x. the round is where sugar rush keeps the bulk of its return: the persistent multiplier spots only build up across free spins, so a session that never triggers the feature is a session that only ever saw the lean base game. at $0.50 a spin a 1-in-324 trigger means a typical $100 bankroll buys roughly enough spins to expect a couple of bonuses, and most sessions that busted simply ran out before a paying one arrived.

what a finished session looks like

final bankroll by percentile

the final-bankroll distribution at $0.50/$100 (default version) has almost no middle. eight sessions in ten ended with under $0.50 of the original $100, busted, in effect, with the median finish near $0.43. then it leaps: the 90th percentile kept $349. like every high-volatility tumble game we have studied, sugar rush sessions overwhelmingly either die or, rarely, run hot; the steady-as-she-goes outcome barely exists despite the high hit rate.

the rtp version lottery

sugar rush ships at 96.50% and the casino can run it at 95.50% or 94.50% instead, a published 2.00pp spread (house edge 3.50% rising to 5.50%) that the player never sees on the reels. we ran the full grid at the 94.50% floor as well; same model, same inputs, only the RTP changed:

cell96.50% default94.50% floordelta
$0.20/$100 bust49.3% ±1.051.9% ±1.0+2.6pp
$0.50/$100 bust82.0% ±0.882.8% ±0.7+0.8pp
$0.50/$200 bust60.2% ±1.063.5% ±0.9+3.3pp
$1.00/$200 bust81.4% ±0.883.5% ±0.7+2.1pp
$0.20/$200 bust6.4% ±0.58.5% ±0.5+2.1pp

the floor version raised the bust rate in every cell measured. the effect is smaller than on a 12-point ladder like Rise of Olympus, because the spread here is only two points, but it runs the same direction every time, and it is free money for whichever operator chooses to run it. the takeaway is the one that holds across our whole library: the version is the one variable a player can actually choose, so play it where the published RTP is highest. our casino hub ranks operators by exactly that.

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 172,889,000 simulated spins (180,000 sessions across two RTP versions), with 95% confidence intervals shown. the bonus payout distribution and the base-versus-feature RTP split are modelled assumptions, so bonus-value figures are estimates; the base-game ceiling (500x) is a reasoned estimate. casino-by-casino RTP figures are the published ladder, not statements about any operator's current configuration. model validation: sugar-rush v1, analytic calibration exact at 96.50%, 10M-spin check measured 96.30% (within tolerance); floor config exact at 94.50%. 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 ~500x (€250). The 5,000x top win is a feature event, it only came out of the bonus. (base-game ceiling: model estimate)
