1. RTP (Return to Player): 95%

This indicates that, on average, a player can expect to get back 95 coins for every 100 wagered. This leaves a 5% edge for the casino, which is relatively standard for many online slots, but it's not particularly high. As a professional player, you would view a 95% RTP as moderate, and thus you'd need to manage your bankroll with care over longer play sessions to account for potential variance.

2. Paylines: 20

The presence of 20 fixed paylines creates a relatively straightforward winning structure. Players can expect less complexity in terms of potential winning combinations compared to slots with a larger number of paylines. This can lead to a more predictable outcome per spin; however, the wins might be less frequent if the volatility is high, given that the volatility is listed as "Unknown".

3. Max Bet Scenario:

By betting the maximum amount of 400, and if you were to hit the maximum win of 100,000, your potential return would be as follows:

Maximum win: 100,000 coins in the slot’s base currency (e.g., USD). While this is an attractive potential payout, such a win comes with high rarity and is often contingent on very specific gameplay events.

4. Minimum Bet: 0.01

The option to place a minimum bet of 0.01 allows for an entry-level exploration of the game, catering to casual players or those testing strategies. At this minimum bet, while the maximum theoretical win remains the same, the calculations would be:

This highlights that even low-stakes players can aspire to substantial wins, but the likelihood of hitting the max win at such low stakes is extremely rare.

Simple Expected Return Calculation:

Assuming you make 1,000 spins with a 1-coin bet (total wager: 1,000 coins), the expected return based on the RTP would be:

This results in an expected loss of:

This means that, statistically, you could expect to lose 50 coins over 1,000 spins. However, actual results may vary significantly due to the nature of gambling, where variance can lead to larger fluctuations in results.
