1. RTP (Return to Player): 94.22%

The RTP of 94.22% indicates that players can expect to receive, on average, 94.22 coins for every 100 coins wagered. This suggests that the casino retains a house edge of approximately 5.78%. With an RTP below the industry standard of around 96%, this slot tends to have a lower expected return, which is an important factor for a professional player to consider.

2. Paylines: 20

This slot features a total of 20 paylines, which provides a moderate number of winning combinations. While it is not as high as some modern slots that offer hundreds or thousands of ways to win, the fixed paylines allow for structured betting strategies. Players should be aware that the limited number of paylines may result in less frequent substantial wins compared to higher-payline games.

3. Max Bet Scenario:

For a professional player placing the maximum bet of $100, the maximum potential win would be capped at $2,500. This means:

100 (max bet) * 25 (max payout multiplier based on max win) = 2,500

Maximum win: $2,500 which serves as a significant but achievable target, bearing in mind the high volatility nature of this game.

4. Minimum Bet: $0.20

The minimum bet of $0.20 makes it accessible for players wanting to try out the game with lower risk exposure. In a maximum win scenario at this bet level, the calculation would be:

0.20 (min bet) * 25 (max payout multiplier based on max win) = 50

Maximum win at minimum bet: $50, which illustrates the disparity in potential payouts based on wager size.

Simple Expected Return Calculation:

Assuming a professional player spins 1,000 times at a 1-coin bet (totalling 1,000 coins wagered), the expected return based on the RTP of 94.22% would be:

1,000 * 0.9422 = 942.2 coins returned

This leads to an expected loss of approximately 57.8 coins over this sample, reaffirming that while some sessions could yield higher returns, the average outcome might be unfavorable.

Risk Evaluation Based on Volatility and Payline Structure

With a designation of high volatility, players should be prepared for potential swings in their bankroll, where sessions may lead to dry spells followed by substantial win opportunities. The 20 paylines combined with high volatility indicates a chance for significant payouts, but they are less frequent. Professional players may find success by implementing aggressive bankroll management strategies to survive the inevitable downturns.
