1. RTP (Return to Player): 96.2%

The RTP of Once Upon a Time is set at 96.2%, indicating that, on average, a player can expect to get back 96.2 coins for every 100 wagered. This leaves a 3.8% edge for the casino. This RTP is slightly above the industry average, making it a reasonably positive choice for players seeking consistent returns over time.

2. Paylines: Unknown

The lack of specific information regarding the number of paylines introduces an element of uncertainty. Without knowing how many ways a player can win, it is difficult to gauge the frequency of payouts. If the game uses a "ways to win" mechanic—common in modern video slots—players might experience more frequent smaller wins. However, if it has fixed paylines, wins may be less frequent but potentially larger.

3. Max Bet Scenario:

The maximum bet limit for Once Upon a Time is 200. As no maximum win value is defined, we cannot calculate the absolute potential win from the game directly. However, players can assess the return based on their wagers. If we assume a potential multiplier is accessed, a player betting 200 might still expect significant gains:

For illustrative purposes, if this game hypothetically had a maximum multiplier of x1,000, the potential win from a max bet would be:

Thus, while maximum wins are unclear, players can generally expect the potential for large payouts under favorable circumstances.

4. Minimum Bet: 0.2

The minimum bet is set at 0.2, making it accessible for players looking to explore the game or manage their stakes effectively. The potential win at the minimum bet with a hypothetical x1,000 multiplier would be:

This demonstrates that even with a minimal commitment, players can still experience profit, albeit considerably lower than the maximum scenario.

Expected Return Calculation:

Assuming a player spins 1,000 times with a 1-coin bet (total wager: 1,000 coins), we can estimate the expected return based on the 96.2% RTP:

Expected loss = 38 coins

This illustrates the long-term average; however, actual results may vary significantly due to the inherent volatility of the game.

Risk Evaluation: Volatility & Payline Structure

Given the volatility is categorized as "Unknown," it imposes a significant risk element that must be taken into account. Volatility affects the frequency and size of payouts; high volatility can lead to larger wins but less frequent payouts, whereas low volatility might see more regular wins of smaller amounts. Players must be cautious here, as engaging with a game of unknown volatility can lead to unexpected losses.

The unknown paylines further complicate risk assessment. A high number of ways to win often allows for more frequent payouts, while fewer paylines could result in a more complicated path to significant wins.
