1. RTP (Return to Player): 94.38%

The RTP of 94.38% indicates that, on average, players can expect to get back 94.38 coins for every 100 coins wagered. This RTP is slightly below the average for online slots, which generally hover around 95% to 96%. This means that players will experience a higher house edge, which is an important consideration for professional players assessing long-term profitability.

2. Paylines: 30

With 30 paylines, Big Thunder offers a moderate level of complexity for winning combinations. Each payline represents a unique opportunity for players to achieve a winning result. Since it is a relatively straightforward structure compared to slots with numerous ways to win, players may experience less variability in potential outcomes, but this also means they need to rely on hoping to hit these fixed paylines.

3. Maximum and Minimum Bet Scenarios:

- Maximum Bet: Let’s analyze the potential win when placing the maximum bet of 3000 coins and achieving the maximum win amount of 1,000,000 coins.

If the player hits the maximum win:

Potential maximum win: 1 million coins. This is a significant payout but achieving this is highly contingent on the game's RNG and bonus features.

- Minimum Bet: With a minimum bet of 0.01 coins, if a player managed to hit the maximum win using this bet level, the calculation would show the theoretical maximum win based on the same win ratio:

That said, over realistic play, the time taken to reach a significant payout from minimum bets is typically slower and less feasible.

Simple Expected Return Calculation:

For a player who spins 1,000 times using a 1-coin bet (total wager: 1000 coins), with the RTP of 94.38%, the expected returns can be computed as follows:

In this scenario, the expected loss would be:

Thus, after wagering 1000 coins, a player would anticipate losing approximately 56.2 coins on average. As with any slot, outcomes are variable and depending on the nature of the spins provided by the RNG.

Volatility Assessment:

The high volatility rating of Big Thunder implies that while players may face longer periods between wins or smaller payout amounts, they stand a chance for larger rewards when substantial wins occur. This volatility may appeal to professional players looking for high-stakes thrills and are prepared to manage their bankroll carefully over time.
