1. RTP (Return to Player): 95.86%

The RTP of *Zombirthday* indicates that, on average, a player can expect to receive back 95.86 coins for every 100 wagered. The remaining 4.14 coins reflect the casino's edge. While this is below the 96% mark typically seen as favorable among players, it is still relatively reasonable. Players should approach this RTP with moderate expectations regarding returns.

2. Paylines: 10

This game features 10 fixed paylines, providing a structured winning combination format. With fewer paylines, players may experience less frequent wins compared to slots with a higher ways-to-win mechanic. The predictability of paylines can both simplify betting strategies and result in longer stretches without significant wins.

3. Max Bet Scenario:

With a maximum bet of 30 coins, hitting the maximum win of 270,000 coins would symbolize the potential for substantial returns. The calculation for maximum win based on the max bet is:

Thus, the maximum win of 270,000 coins is enticing. However, such a payout is rare and can often take considerable playtime to achieve, highlighting the game is likely designed with high variance.

4. Minimum Bet: 0.2

For players looking to test the waters with minimal risk, the minimum bet is set at 0.2 coins. The potential maximum win under this betting scenario can be calculated as follows:

Even with the minimum bet, the maximum potential win remains 270,000 coins, emphasizing the lucrative payout structure regardless of the betting scale.

Simple Expected Return Calculation:

Assuming a player spins the slot 1,000 times at a 1-coin bet (total wager: 1,000 coins), with an RTP of 95.86%, the expected returns would be calculated as follows:

This yields an expected loss of 41.4 coins over the same number of bets. Although this calculation serves as a theoretical outlook, it does not guarantee that results will align with expectations, as slot outcomes can be highly variable.

Risk Evaluation:

With the volatility set as "Unknown," players may find it challenging to gauge the risk accurately. The combination of a standard 5x3 grid and 10 paylines suggests a moderate volatility level, but without explicit classification, one should exercise caution. The limited paylines mean that a player's experience could lead to either consistent, smaller returns or extended periods of lower payouts interspersed with larger wins.
