1. RTP (Return to Player): 96.1%

The RTP of 96.1% indicates that, on average, a player can expect to recover 96.1 coins for every 100 wagered. This represents a relatively strong RTP, suggesting a balanced chance of return compared to many other slots. The 3.9% edge held by the casino is fairly standard, so players should be prepared for minor losses over time.

2. Grid and Paylines: 3x3 Grid with 27 Paylines

Steam Vault has a 3x3 grid structure, offering 27 paylines. This configuration suggests that players will have a variety of ways to achieve wins on each spin. The relatively small grid size could mean that wins are more frequent but likely of smaller value. Players should be mindful that while there are numerous winning combinations, being on a 3x3 grid may limit the potential for massive payouts.

3. Max Bet Scenario:

By placing the maximum bet of 500, and assuming a hit of the maximum payout of 2500 (the game's stated maximum win), the potential return from such a scenario would be:

Maximum win: 2,500 in the slot’s base currency (e.g., USD, etc.). This level of payout is achievable but isn't frequent, reflecting the game's designed volatility.

4. Minimum Bet: 1

With a minimum bet of 1, the maximum achievable win remains at:

This shows that even players engaging with the minimum bet could theoretically strive for the same win capped at 2,500.

Simple Expected Return Calculation:

If we consider a player who spins 1,000 times with a 1-coin bet (total wager of 1,000 coins), and based on the RTP of 96.1%:

Expected loss = 39 coins

While this is a statistical expectation, actual gameplay can lead to scenarios where players either earn less or significantly more, particularly if they hit bonus features or high-multiplier combinations.
