Slot Summary

Catching Bass symbols outside the paylines gives 9 Bass its defining split between ordinary line wins and symbol collection. Oros Gaming pairs that direct Fish mechanic with a Free Spins wheel, payline multipliers, and a top award for landing 9 Bass at once. The familiar 5x3 format therefore serves two scoring routes rather than relying only on left-to-right combinations.

How It Plays

Ordinary symbols pay across 20 paylines from left to right, while Bass symbols use a separate count-based rule and do not need payline alignment.

The strongest collection result comes from landing 9 Bass symbols together. This awards x2000.00, which is also the game's listed maximum win.

Theme & Atmosphere

Fish, Sea, and Nature themes are expressed through the act of catching Bass, giving the count-based prize mechanic a clear subject and objective.

Traditional slot symbols remain part of the presentation, but the Bass symbols carry the thematic weight because their quantity directly determines the separate cash award.

Nature Fish Sea

Features & Win Potential

The Bonus wheel is activated by Free Spin symbols on the middle reels. Its result can award Free Spins together with a payline Multiplier.

Wild and Scatter symbols support the ordinary reel game, while the 9 Pots mechanics give the scattered Bass count its own escalating prize route.

Bonus & Free Spins

The Free Spins wheel determines both the number of awarded spins and the accompanying Free Spins Multiplier, creating several possible starting packages.

Additional Free Spins can be won when the required Free Spin symbols land again during the round, extending the feature without changing its core rules.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (96.24%), with wins capped at its top multiplier (2,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
