Sweet Bonanza (Pragmatic Play) — 96.52% observed, the "free-spin tax" trap. Score 8.5

Bench window: 25,108 spins at ₱1-₱20 stakes over 12 days on HOYY production build 26.04.08. This is our most-played Pragmatic title on HOYY by volume.

Observed RTP

96.52% vs 96.51% certificate — within 0.01, excellent consistency.

Session volatility

High. 20-spin standard deviation 2.68× bet. Max session loss 89× bet. Max session win 1,860×. 90-percentile session range −24× to +52×. Budget generously: 100-spin session at ₱5 stakes — minimum ₱1,000 floor to be comfortable.

Payout mechanics — the structural issue

Base-game free-spin trigger rate: approximately 1 in 330 spins in our bench. That's low — noticeably lower than 2024 Pragmatic releases in the same slot category (typically 1 in 200-260). Result: the base-game path feels "dry" to most players, which creates psychological pressure toward the 100× bet bonus buy.

The bonus buy itself runs at 96.1% observed — slightly under base-game, typical trap. The issue isn't the bonus-buy RTP, it's that the base game is engineered to discourage patience. Statistically this doesn't change expected value, but experientially it pushes players toward higher-variance decisions.

Mobile UX

Good. Art ages well, sound layer is excellent. Ante-bet feature (25% bet premium, doubles trigger rate) is the correct middle path if you want bonus action without the bonus-buy RTP hit.

Verdict — 8.5

Strong buy with caveat. Clean observed RTP, high variance done well, excellent production. The free-spin-trigger engineering is a real issue but it's disclosed; players who understand it can manage it (use ante-bet, skip bonus-buy). Not for patience-poor players or small-bankroll sessions.
