1. RTP (Return to Player): 92.99%

The RTP of 92.99% indicates that, on average, a player can expect to receive approximately 92.99 coins back for every 100 coins wagered. This puts the house edge at roughly 7.01%, which is notably higher than the industry average for online slots, often around 96% or more. This lower RTP suggests that players can expect less favorable returns over the long term.

2. Grid Structure: 4x3

Mad Scientist Scratch has a grid structure of 4x3, which means there are 4 rows and 3 columns. While the exact number of paylines is not specified, this grid format typically results in a limited number of winning combinations compared to larger grids. The 4x3 format can lead to more predictable and often smaller wins, aligning with the game's low volatility.

3. Max Bet Scenario:

At a maximum bet of 150, the maximum win amount is capped at 1,000. If we assess this potential maximum win at max bet:

Maximum Win: 1,000 coins.

This value signifies that regardless of the stake, the highest achievable payout upon winning is fixed at 1,000 coins.

4. Minimum Bet Scenario:

With the minimum betting amount set to 0.3, the maximum gain remains at 1,000 coins. The potential scenario for max win at minimum stake would yield:

This implies that even at the lowest stakes, players can only win a small fraction of the max win, enhancing the game's position toward low-risk sessions.

Expected Return Calculation:

If a player spins 1,000 times with a 1-coin bet (assuming we normalize bets to 1 coin for easier calculations), with an RTP of 92.99%:

Expected loss = 70.1 coins.

This highlights the game's lesser profitability over time, reinforcing the idea that players will often experience losses greater than wins with consistent gameplay.

Risk and Volatility Assessment:

The low volatility rating suggests that the game tends to produce wins more frequently but at smaller amounts. This scenario can be appealing for beginner players or those looking to sustain their bankroll through longer play sessions without facing large swings. However, the low RTP and max win limit may limit the thrill for more experienced players seeking substantial payouts.
