Bench window: 18,340 spins at ₱1.50-₱15 stakes over 10 days on HOYY production build 26.04.07.
Observed RTP
96.22% against the 96.20% Jili certificate — clean, no tuning concerns.
Session volatility
20-spin session standard deviation: 2.14× bet size. Max session loss 47× bet, max win 724×, 90-percentile session range −17× to +38×. Higher variance than Super Ace (1.83×) — expected, given Mega Ace's symbol hierarchy places more weight on high-multiplier combos.
Payout mechanics
Base-game hit frequency 24.6%. Free-spin trigger rate approximately 1 in 215 organic spins. Bonus-buy at 100× bet returned 96.0% observed RTP in our window — slightly under base-game, same trap pattern as Super Ace. Skip the bonus buy here too.
Mobile UX
Testing on Redmi Note 10 (Android 12). Spin-speed slider fine; turbo ~0.8s. Tap targets slightly larger than Super Ace, fewer mis-taps (2 per 500 spins vs Super Ace's 3). Sound design fatigues faster — repetitive horn stabs get tiring around minute 35. Mute and play music.
Verdict — 8.7
Strong buy but not an Editor's Pick (reserved for 9.0+). Higher variance than Super Ace so budget more. Bonus-buy still a trap, skip it. If you've maxed out Super Ace and want a rotation title with similar pedigree but different session shape, this is it.
