Every fourth portrait is flagged for a retrigger before you spin

Watch the intro screen and the design gives itself away before a single spin: a wooden board of twelve fisherman portraits, every fourth slot marked for a retrigger, so the whole build visibly revolves around collecting Wilds once the Scatter round begins. Three bass open ten Free Spins, four open fifteen and five open twenty, and inside the round every fourth fisherman adds ten more spins while lifting the Money Collect Multiplier through ×2 and ×3 to ×10. It is also the plainest statement of a long-running formula: a simple Reel fishing trip over an Ocean life backdrop, dated December 2020, before the sequels repainted that trip as horror nights, Christmas lakes and race days. High volatility and a 96.71% return complete the original blueprint.

Ways to play

The first thing you notice missing from the reels of Big Bass Bonanza is the Fisherman: his Wild never lands in the base game, because substituting and collecting are both reserved for the feature. One 5x3 grid with ten Lines carries the two modes, and the arithmetic that connects them is a matter of counts: Scatters to get in, every fourth Wild to keep going.

Base Game	Wins are settled on ten fixed Lines running left to right from the leftmost reel, and the bookkeeping is strict: only the highest win on each line is paid, while hits on several lines at once are added together. The Wild is withheld from this state, so nothing here substitutes for other symbols, and it takes three or more Scatters landing at once to leave these reels for the feature.
Free Spins	The Scatter count that opens the round also sets its length: three, four or five award ten, fifteen or twenty spins, played on special reels. The Fisherman Wild lands on all five reels here and collects the value of every Money symbol in view, each worth 2x to 2,000x the total bet; every fourth Wild on the twelve-slot tracker adds ten more spins, three times at most, while the collection Multiplier steps to x2, x3 and x10, and a running total of 2,100x ends the round immediately.

How to place a bet

The first thing you notice is the view from below the surface: teal water, bubbles climbing between the reels, sunlight slanting down. Beneath it sits a 5-reel build with 10 Lines, rated High for volatility. Each round asks one decision, the stake, and the spin cycle aims at the Free Spins feature, where the fisherman collects what the fish are worth.

Set the stake

Use the plus or minus button to open the bet menu, then set the total bet anywhere between $0.10 and $250.00. Clicking the CREDIT or BET label switches the shown amounts between cash and coins.
Spin the reels

The spin button starts the round, and SPACE or ENTER does the same; keeping SPACE held runs a turbo spin. Wins pay left to right on adjacent reels from the leftmost, across the 10 Lines, with only the highest win paid per line.
Land Scatters for Free Spins

Repeat the spin cycle until three or more Scatter symbols land at once, which opens the Free Spins round on special reels. Every Wild fisherman collects all money values on screen, and each fourth Wild collected adds 10 more spins and raises the Multiplier, up to 10x.
