1. RTP (Return to Player): 95.53%

The RTP of 95.53% indicates that, on average, players can expect to recover 95.53 coins for every 100 bet. The remaining 4.47 coins constitute the house edge. This RTP is moderately low compared to industry standards, suggesting that players could experience slightly less favorable returns than higher RTP slots over extended gameplay.

2. Paylines: 30 (Both Ways)

Having 30 paylines that pay in both directions effectively doubles the number of winning combinations compared to traditional one-way paylines. This design can lead to more frequent wins, albeit typically modest ones, which suits players who appreciate regular payouts without the high volatility typically associated with fewer paylines.

3. Max Bet Scenario:

With a maximum bet of 90 and a disclosed maximum win of 4,050,000, if a player places this maximum bet during a winning spin, the calculations for potential maximum payouts become sheerly impressive:

Maximum win: 4,050,000 in the slot’s base currency. While this is theoretically attainable, actual occurrences of such wins are rare and would likely require significant luck.

4. Minimum Bet: 0.3

For players who prefer a conservative approach, the minimum bet of 0.3 allows for low-stakes gaming. Using this bet level, the maximum theoretical win would be:

This results in a potential win of 13,500 coins, providing a reasonable upside while managing the downsides of risk.

Simple Expected Return Calculation:

Assuming a player spins 1,000 times with a 1-coin bet (i.e., 1 coin being equivalent to the unit currency of 1, calculating with minimum or standard bet), the expected return based on the RTP can be computed as follows:

This indicates an expected loss of approximately 44.7 coins over that period, reflecting the variance inherent in gambling and slot play. It's essential to note that these figures represent averages over time rather than guarantees of individual gameplay outcomes.

Risk Evaluation Based on Volatility and Payline Structure

The low volatility rating of this slot suggests that players may expect to see smaller wins more frequently, which may suit those looking for a less risky experience. The dual-direction paylines add to this effect by giving players additional opportunities for wins with every spin. However, players should be cautious not to confuse frequent, smaller wins with potential large payouts, which are still achievable but rarer.
