CVaR takes exactly 0.10% of the weighted mass, splitting the boundary payout (111×) when needed. This measures the operator’s gross payout tail, without subtracting participation cost.

HOW THE MATH WORKS

One paid round, including its bonus

The 5-reel, 4-row game pays on 20 lines from left to right. Three or more matching symbols pay; Wilds substitute for paying symbols. Winning symbols clear and new symbols cascade into the grid. Base cascade multipliers are 1×, 2×, 3× and then 5×.

Three, five, six or seven paying base cascades award 6, 8, 10 or 12 free spins. Free-spin bonus factors are 2×, 6×, 8× and 10×. The carried multiplier step is capped at 30; the factor applies to that step. Retrigger thresholds begin at four free-spin cascades, and a stronger award can upgrade the remaining bonus. The full-round payout is capped at 5,000×.

Paytable and rounding

Raw line pays for 3 / 4 / 5 matching symbols are in twentieths of the base stake. The base scale is 0.47266439855548 and the free-spin scale is 0.16854447986270668, applied before the cascade multiplier. Cumulative payouts are rounded across the paid round to 0.1× increments.

Generator samples and final selection weights

The corpus is a finite set of complete outcomes. Final lookup weights define the probability of each recorded round; raw occurrence counts do not. The v4 export includes separately weighted rare outcomes, including cap-reaching rounds. Their generation frequency is not a natural-frequency estimate.

METHODOLOGY & DOWNLOADS

Definitions and exact arithmetic

For outcome i, pᵢ = wᵢ / Σw and xᵢ = payoutᵢ / (100 × mode cost). RTP = 100 × Σ(pᵢxᵢ). Standard deviation = √[Σ(pᵢxᵢ²) − mean²]. Hit = P(x > 0); profit = P(x > 1). Frequency = 1 / probability, including the event round.

Integer weight sums and rational RTP / band contributions are retained exactly. Zero-weight records count toward corpus size but cannot define reachable payouts. Display values are rounded; JSON retains numeric precision and exact rational band values. No confidence interval is needed for this finite weighted distribution.

No Low / Medium / High volatility label is assigned without a defined classification scale. External profiles and monetary risk remain unevaluated when their required configuration is absent.
