1. RTP (Return to Player): 96.49%

This RTP indicates that players can expect to receive back 96.49 coins for every 100 coins wagered, with the remaining 3.51 coins representing the casino's edge. This RTP is relatively standard and points to a balanced slot experience – not too low to deter players nor particularly high to suggest extreme generosity.

2. Paylines: 18

The game features 18 fixed paylines, which allows for a moderate number of winning combinations. This structure suggests that players can expect to land winning combinations with decent regularity. With medium volatility, wins should be steady but not overly frequent, allowing for some exciting gameplay without frustrating long dry spells.

3. Max Bet Scenario:

The maximum bet for this slot is €180. Given the maximum potential win of €1,000, this suggests that the slot may have a built-in limit on payouts for high-risk stakes, which is crucial for professional players to be aware of.

If a player were to place the maximum bet of €180, their potential returns could be logically assessed as follows (noting the 1,000 win amount is a direct maximum and could be less than the total wagered):

While the potential max win caps at €1,000, the return for a single max bet scenario won't exceed this, making it reasonable for players to expect their largest wins falling well below their total bets in a single session.

4. Minimum Bet: €0.18

At the minimum bet of €0.18, players have a lower-risk avenue for exploring the game. The maximum win remains €1,000, indicating that players can still achieve a sizable win even with minimal investments, though the likelihood of achieving the max win at such a low stake becomes incredibly slim.

Expected maximum payout calculation with a minimum bet becomes:

While the max win is consistent at €1,000, the overall move will require considerable betting sessions to approach this outcome.

Simple Expected Return Calculation:

Considering a player spins 1,000 times at a €1 bet (total wager: €1,000). With an RTP of 96.49%:

Expected loss = €35.10

However, results will vary; it's possible to have prolonged losing streaks or surprise high wins, as this does not reflect the inherent variance in slot play.

Risk Evaluation: Volatility and Payline Structure

Given the medium volatility of Mermaid, players can expect an average gaming experience characterized by regular wins. However, significant rewards might be less frequent and more challenging to trigger. This volatility coupled with the 18 paylines suggests a balanced slot designed for players who enjoy moderate risk without the extreme highs and lows found in high-variance slots.
