1. RTP (Return to Player): 96.37%

The RTP of 96.37% indicates that, on average, players can expect to receive back 96.37 coins for every 100 wagered. The remaining 3.63 coins represent the casino's edge. This RTP is slightly above the industry average, making the slot relatively favorable for players in terms of expected returns.

2. Grid Structure: 5-3x4

The grid structure of 5-3x4 suggests that there are 5 reels and 3 rows of symbols. This layout can potentially offer a varied number of winning combinations depending on the game's mechanics, even though the exact number of paylines is unknown. The lack of specific paylines means that the game may operate on a "ways to win" basis, typical of modern slot designs, which can lead to more frequent, smaller wins.

3. Maximum Bet Scenario:

With a maximum bet of 10 coins, the potential maximum win of 2820 coins can be analyzed. If a player were to hit the max win, the scenario would be:

So, the maximum payout when placing the maximum bet is 2,820 coins. This payout is reasonable but does suggest some limitations in volatility or max win potential compared to higher variance games.

4. Minimum Bet: 0.25

For players who opt to start with a minimum bet of 0.25 coins, the maximum theoretical win remains at 2,820 coins as well. The expected payout would then be:

At this minimum bet level, the player’s maximum win is 70.5 coins, allowing for lower risk gameplay.

Simple Expected Return Calculation:

If a player spins 1,000 times with a 1-coin bet (total wager: 1,000 coins), the expected return based on the RTP of 96.37% would be:

This calculation results in an expected loss of 36.3 coins. However, it is essential to remember that these calculations reflect average outcomes over time. Actual results can vary significantly, especially when big wins are involved.

Risk Evaluation Based on Volatility and Payline Structure:

The volatility of this game is listed as "unknown", which makes it hard to assess the risk accurately. In the absence of a known volatility rating, we can only infer that the gameplay experience may vary widely depending on the underlying mechanics intended by the game provider. The unknown paylines may also indicate that payouts can be unpredictable.

Despite the potential for a slightly favorable RTP, players should remain mindful of this aspect — particularly for those who are risk-averse or with tighter bankrolls.
