fat santa is the 2018 Push Gaming festive hit, the studio's first buy-a-bonus slot, built around a growing wild Santa and a 10,223x ceiling. we simulated 105,037,324 spins of its 96.45% published version. at $0.50 a spin against a $100 bankroll, 72.2% of sessions busted before the 2,000-spin cap, a touch gentler than the high-volatility average thanks to its medium volatility.

model inputs worth flagging: the 96.45% RTP and the 80x buy are sourced; the max win is reported as 10,223x by the better-sourced reviews (a 6,405x figure is a single-source outlier we reject). a 94.15% lower version is reported single-source, so we do not simulate a floor. Push does not publish a hit frequency or bonus trigger rate, so both were modelled (about 26% hit, one feature every ~167 spins) as documented assumptions; the bonus payout distribution and the ~250x base-game ceiling are model assumptions calibrated to the published RTP and the 10,223x cap.

how long bankrolls survived

survival curves, share of sessions still alive vs spins played

the stake sets the clock. at the $100 bankroll the median session ran 827 spins at $0.50, a little longer than our high-volatility studies, because medium volatility means smaller, steadier swings. the growing-wild free spins still carry most of the return, and most bankrolls run dry before a big one lands.

bust rates

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

bust rates within the 2,000-spin cap, 96.45% version, 95% confidence intervals:

$50 bankroll$100$200
$0.20/spin65.0% ±0.928.2% ±0.90.1% ±0.1
$0.50/spin87.5% ±0.772.2% ±0.942.0% ±1.0
$1.00/spin93.7% ±0.587.6% ±0.772.9% ±0.9

plain reading: hold the bankroll at $100 and move the stake from $0.20 to $0.50, and the bust rate jumps from 28.2% to 72.2%. the only safe cell is $0.20 against $200 (0.1%).

the bonus wait, and what it pays

on our modelled trigger rate (about 1 in 167 spins, an assumption), the feature carries about 50% of the total return. the payout side (model-based estimates): the average feature paid 80x stake but the median was 44x, and 55% paid under 50x. the 10,223x ceiling is the rare tail; a typical feature pays around half the average. the 80x buy, Push Gaming's first, lets a player skip straight to the growing-wild round, paying the same negative-expectation math, faster.

what a finished session looks like

final bankroll by percentile

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 $0.36. then it leaps: the 90th percentile kept $309. the same die-or-detonate shape as the rest of our library, though medium volatility softens the edges slightly.

on the version question

we simulate the 96.45% published version. a 94.15% lower version is reported by a single source, so we do not simulate a floor for fat santa. the general rule still applies: 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.

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 105,037,324 simulated spins (90,000 sessions), with 95% confidence intervals shown. we simulated the 96.45% published version; a 94.15% version is single-source and not modelled. hit frequency and bonus trigger rate are not published and were modelled as documented assumptions; the bonus payout distribution and the ~250x base-game ceiling are reasoned estimates, not sourced. max win 10,223x (a 6,405x figure was rejected as an outlier). model validation: fat-santa v1, analytic calibration exact at 96.45%, 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

base 48%
feature 48%

50% of this game's RTP is locked inside the bonus you rarely trigger; the base game on its own returns just 48%.

A normal spin in our simulation never returned more than ~250x (€125). The 10,223x top win is a feature event, it only came out of the bonus. (base-game ceiling: model estimate)
