1. RTP (Return to Player): 94.72%

The Return to Player percentage of 94.72% indicates that, on average, players can expect to receive back 94.72 coins for every 100 coins wagered. This RTP is below the industry average (typically around 96-97%), meaning the house edge is relatively high, which is significant for players evaluating the long-term potential profitability of the game.

2. Paylines: 30

With 30 paylines, Rio Stars allows for a limited yet structured set of winning combinations. This is a moderate number of paylines, suggesting that while players can achieve wins on various combinations, the frequency may not be as high as slots with more complex payline structures or "ways to win" mechanics.

3. Max Bet Scenario:

The maximum bet for Rio Stars is 40 coins. Given the maximum win cap of 2,000 coins, players hitting the top multiplier (though not detailed) under maximum bet conditions would realize a potential maximum win of:

In this context, the maximum theoretical win stands at 2,000 coins, which could be achieved through multipliers and combinations.

4. Minimum Bet: 0.20

For players looking for lower risks or testing out strategies, the minimum bet of 0.20 is ideal. Assuming maximum potential winnings similar to the max bet scenario, the maximum win from the minimum bet could be:

This suggests that wins could reach up to 10 coins, should players manage to hit maximum values similar to their higher-stake counterparts.

Simple Expected Return Calculation:

For a detailed understanding of expected returns, a player who spins 1,000 times with a 1-coin bet (total wager: 1,000 coins) would calculate their expected return based on the RTP of 94.72%:

Expected loss = 52.8 coins. This expected return assumes an average long-term play but does not take into account the inherent variance of the game—wherein a player may either win significantly or experience prolonged periods without substantial returns.

Risk Evaluation: Volatility and Payline Structure

Rio Stars is categorized as a high-volatility slot. High volatility indicates that while the potential for large wins exists, payouts may be infrequent. This volatility complements the existing structure of 30 paylines, which may provide moderate winning opportunities but can lead to longer dry spells in the game session.
