Detailed Explanation
To calculate the expected value (EV) of the bonus buy feature in Mahjong Wins Super Scatter Slot, use the formula EV = (Average Payout × Probability of Outcomes) – Bet Cost, adjusted for stake levels where payouts scale proportionally but costs remain fixed at 100x the stake.
This Pragmatic Play 5×5 slot with 2,000 Ways to Win features an RTP of 96.50%, high volatility, and a staggering 100,000x max win. The bonus buy instantly triggers free spins for 100x your stake, bypassing the base game's 29.32% hit frequency. Payouts depend on super scatters (gold scatters on middle reels) combined with 3+ scatters: 1 super scatter pays 50x, 2 pays 500x, 3 pays 5,000x, and 4 pays 100,000x the stake.
For a €1 stake, bonus buy costs €100. Estimated probabilities (from simulations) are roughly 60% for low payouts (under 100x), 30% for mid (100-1,000x), 9% for high (1,000-5,000x), and 1% for jackpots, yielding an average return of about €105 and positive EV of +5%. At €10 stake (cost €1,000), EV scales to +€50 due to proportional payouts.
- Tip 1: Buy at lower stakes (€0.20-€1) for better relative EV, as fixed probabilities favor smaller bets.
- Tip 2: Track 100+ buys to verify; avoid if RTP drops to 94.50% in some casinos.
- Tip 3: Combine with tumble multipliers (up to 5x) for chained wins in the feature.
Always play responsibly, as EV is long-term and short-term variance is extreme.
