Our take
Fishing-themed 5×3 medium-volatility from Oros Gaming with 94.91% RTP, Epic Strike instant scatter, and 2000× max.
9 Bass is Oros Gaming's debut on Microgaming, a fishing-themed slot combining the popular Epic Strike instant-scatter-prize mechanic with medium volatility. The 5×3 layout offers 20 paylines, and the 94.91% RTP sits at the industry floor—serviceable but not premium. Bets range across a typical spread, appealing to diverse bankroll sizes.
The gameplay hook is the Bass symbol: landing nine in view triggers a significant win, immediately differentiated from standard scatter or wild mechanics. This direct symbol-count threshold creates anticipation during play. The Epic Strike mechanic—instant, unannounced scatter prizes—adds a surprise-win layer alongside the formal bonus structure, creating two distinct win pathways.
Visually, the slot leans on a static fishing backdrop with modest symbol animation. Reviews note limited visual detail in the setting, but the core gameplay (Bass chases, instant-scatter hits, free spins) compensates. Medium volatility keeps session play steady without flattening ceiling potential; 2000× max win rewards commitment without demanding rare-win luck.
Pros
- Epic Strike instant-scatter mechanic adds surprise-win moments outside the bonus round
- Bass-symbol count (9 for max) creates distinct, anticipatory win condition
- Medium volatility balances regular hits with meaningful top-end potential
- 2000× max win provides solid upside for the volatility profile
- Free spins and wild symbols layer multiple payoff routes
Cons
- 94.91% RTP is at industry floor; not premium compared to 96%+ alternatives
- 20-payline layout limits win frequency vs. cluster-pays or Megaways
- Static fishing backdrop described as limited in visual detail
- Fishing theme is well-worn (many competitor titles in the genre)
- Epic Strike mechanic, while novel, may feel arbitrary or exploitative to some
