The Ante Bet feature nudges this up to 96.50% by increasing the frequency of bonus triggers. The Bonus Buy options offer various RTPs, with the highest being 96.43% for the most expensive tier.
Variance Analysis
The slot's high volatility is driven by its top-heavy paytable and the significant multipliers available through the Bonus Game. The Red and Black Fleas can amplify wins considerably, contributing to the game's potential for large payouts.
Line Density Evaluation
The 20-line setup ensures that individual line wins can be substantial, especially when augmented by multipliers. This contrasts with many high-volatility slots that employ more ways-to-win structures.
Hit Frequency Implications
With a hit frequency of 24.71%, players can expect regular base game wins, but significant payouts are more likely during the Bonus Game.

Given the game's high volatility, a starting bankroll of at least 300x the bet is recommended to sustain play through potential dry spells. Expect the Bonus Game to trigger approximately every 188 spins.
EV Considerations
The Bonus Buy feature presents a slightly negative EV compared to organic triggers, but the increased RTP of the highest buy tier can justify the cost for impatient players seeking quick feature access.
