1. RTP (Return to Player): 96.63%

The RTP of 96.63% indicates that, on average, a player can expect to retrieve 96.63 coins for every 100 coins wagered. This designates a casino edge of approximately 3.37%, making it a relatively standard return in the context of online slots. This RTP suggests a balance between risk and return for players.

2. Grid Structure and Paylines: 5-4, 25 Paylines

The game boasts a 5-reel by 4-row grid structure combined with 25 active paylines. This configuration provides a diversified number of winning combinations, which can lead to both frequent but potentially smaller payouts, depending on the volatility level set by the player.

3. Max Bet Scenario:

For players who are willing to place the maximum bet of 500, the expected maximum win is capped at 10,000 coins. This means that if all winning conditions are met, a player could potentially achieve the following profit:

In real terms, this represents a substantial win, although it may be difficult to attain given common game mechanics.

4. Minimum Bet Scenario:

Conversely, players starting with the minimum bet of 0.10 would see their maximum theoretical win limited. The calculation becomes:

This illustrates that even with a minimal investment, the potential reward can be significant, useful for cautious strategies or testing the game mechanics.

Simple Expected Return Calculation:

Assuming a player participates in 1,000 spins with a 1-coin bet (total wager of 1,000 coins), with an RTP of 96.63%, the calculation is as follows:

Expected loss = 33.7 coins

Again, this serves as an average estimate; actual outcomes may vary depending on variance and game features.

Risk Evaluation Based on Volatility and Paylines:

The adjustable volatility feature allows players to potentially select their risk level, which significantly influences gameplay experience. Higher volatility generally results in fewer but larger wins, while lower volatility may yield more frequent but smaller payouts. With a 25-payline structure, players benefit from multiple winning opportunities on each spin, though the combination of adjustable volatility means that overall risk can widely fluctuate depending on player preferences.
