1. RTP (Return to Player): 94.53%

The RTP of 94.53% signifies that, on average, a player can expect to retrieve 94.53 coins for every 100 coins wagered. The remaining 5.47 coins represent the casino’s advantage. While this RTP is slightly below the industry average of 96%, it is still acceptable for players who understand the risks involved and are looking for entertainment rather than guaranteed returns.

2. Paylines: Cluster Pays

"Cluster pays" means that wins are determined by forming clusters of matching symbols rather than traditional paylines. This structure offers a different mechanism for wins, potentially leading to more frequent smaller payouts as players combine symbols in different configurations. However, the nature of cluster mechanics can sometimes make it challenging to predict the frequency and size of wins.

3. Max Bet Scenario:

With a maximum bet of $100 and assuming a player hits the top prize of $5,000, the maximum return by hitting the maximum payout would be as follows:

Maximum win: $5,000 when hitting the maximum payout at max bet. It's worth noting that achieving this payout would depend on rare events and significant luck.

4. Minimum Bet: $0.20

For those looking to minimize risk, the minimum bet of $0.20 allows players to engage in the game without a substantial financial commitment. The maximum return at this bet level can be calculated as:

Thus, the theoretical maximum win on a minimum bet becomes:

Therefore, strong potential with low risk can yield a payout of $10 for hitting the maximum win while betting the minimum.

Simple Expected Return Calculation:

Supposing a player bets $1 per spin and spins the reels 1,000 times (total wager: $1,000). With an RTP of 94.53%:

This means the player could expect to receive back approximately $945.30, leading to an expected loss of about $54.70. However, actual results are inherently variable—large wins can occur alongside long stretches of losing spins.

Volatility Assessment:

With a medium volatility rating, "Double Rainbow" presents a balanced risk-reward ratio. Players can anticipate a blend of moderate wins with opportunities for larger payouts, but the frequency of significant wins may not be as high as in low-volatility games. This makes it suitable for players who are comfortable with moderate swings in their bankroll.
