Two distinct machines sit behind the Free Spins Choice screen

Three scatters do not open a bonus round here. They open a decision. The Free Spins Choice screen splits Big Bass Mission Fishin' into two different machines. Free Spins keeps the Money Collect ladder. Fish carry values up to 5000x, and the Wild gathers them. Every retrigger lifts the Progressive Multiplier: 2x, 3x, then 10x. Stack the Cash is a Hold and Spin instead. Coins top out at 25x, but each one landed resets the four respins, and a bomb can double a whole reel. One mode concentrates value in the collector. The other spreads it across the grid and lets it build. High volatility and the 5000x cap sit over both. Judging this slot means judging the choice.

Step-by-step guide to playing

Pragmatic Play's Big Bass Mission Fishin' pairs 10 Lines with High volatility. Play loops toward one decision. Three or more Scatter symbols open a pick between Free Spins and Stack the Cash. The selected feature runs to its payout.

Enter and set the bet The round arrow button on the intro screen starts the base game. The plus and minus controls set the total bet. An optional Ante Bet costs 1.5x the bet, adds Scatter symbols, and disables BUY FEATURE.
Reach the mission choice Two routes reach the mission choice. The SPIN button cycles the 10 Lines until 3 or more Scatter symbols land. Exactly 2 Scatters can randomly gain a third through a Respin or a hook. BUY FEATURE costs 100x the bet and, once confirmed, reaches the same screen.
Choose a mission SELECT YOUR MISSION offers FREE SPINS and STACK THE CASH. Free Spins opens SELECT UPGRADES. This Pick Bonus reveals modifiers until a boot icon stops it. Stack the Cash is a Hold and Spin board starting with 4 Respins.
Play the feature to the end In Free Spins, each Wild collects every Money symbol value. Every fourth Wild retriggers 10 spins at a stronger Multiplier. In Stack the Cash, coins lock and reset the Respin count. Filled reels collect and clear. Bombs drop on coin hits and double a random reel. The round then pays its total.

Bankroll strategy and session volatility

The rules print one RTP across every stake option. The figure is 96.50 percent for normal play, Ante Bet, and the Buy Feature. Three decisions sit beneath it. One raises the stake for a higher trigger chance. One buys direct feature entry; those two never combine. The last picks which feature actually plays.

Ante Bet: higher trigger chance, Buy Feature locked

The Ante Bet toggle sits in the base game and can be switched back off. On, it reprices the stake at 1.5x the total bet. In return the rules state a higher natural feature chance; no rate is printed. The stated RTP stays 96.50 percent. While the toggle runs, the Buy Feature is disabled.

Buy Feature: 100x for immediate feature entry

The Buy Feature is offered in the base game only while Ante Bet is off. The dialog can be cancelled before confirmation. Confirming charges 100x the current total bet. The purchase opens the same Select Your Mission screen as a Scatter trigger. The mission itself is picked afterwards. The rules print the same 96.50 percent RTP for bought entry; the round's payout stays random.

Select Your Mission: exactly one feature plays

The Select Your Mission screen follows every trigger and accepts exactly one pick. Free Spins resolves through Wild collection and retriggers. Stack the Cash resolves through locked coins and doubling bombs. The unchosen feature does not run. The rules publish no return difference between the two branches. Recorded sample wins are single random outcomes, not branch properties.

How the game plays out

Five entries, one grid. A 5x3 layout with 10 fixed lines carries every state on this page. Scatters decide which of the two bonus rounds follows, and the two stake controls exclude each other.

Base Game: Wins land on 10 fixed lines, counted from the first reel leftward. Every other card on this page starts from this state. Three or more Scatters on these reels open the Select Your Mission screen, where one of the two features takes over.
Ante Bet: This toggle reprices the base state at x1.5 the total bet. More Scatters sit on the reel strips in return, so the feature triggers naturally more often. The trade-off: Buy Feature stays locked while Ante Bet is on.
Free Spins: The Scatter count sets the starting length: 3, 4 or 5 Scatters award 10, 15 or 20 spins. A pre-round card reveal assigns modifiers first. Each Wild then collects every Money value on screen, and every fourth Wild adds 10 spins and steps the collection multiplier up, to 10x at level 4.
Stack the Cash: The other branch of the same Scatter choice. Normal symbols leave the strips; only Fish Coins and blanks remain. Each coin locks and resets four respin lives. A full reel empties into the robo-crab beneath it, and random bombs double one reel's coins and crab. When the lives run out, all five crab totals are paid.
Buy Feature: One purchase, priced at 100x the total bet, replaces the Scatter trigger. Confirmation leads to the same Select Your Mission screen, where Free Spins or Stack the Cash is picked. It never combines with Ante Bet; that toggle disables it.

Final verdict

Pros

The 96.50% RTP holds on standard spins, ante bet, and the 100x buy alike, so no route quietly charges more.
One purchase or trigger opens a real choice: collect-driven free spins or the Stack the Cash hold-and-respin round.

Weaknesses

The wild never lands in the base game, so ten fixed lines carry a high-volatility grind between features.
The 5,000x cap cuts any round short and forfeits remaining spins the moment it is reached.

Most of this build's value sits inside its two bonuses, and the flat return means chasing them costs nothing extra on paper. The price is a bare base game and a ceiling that can end a hot round early. It suits a player comfortable buying or grinding toward features, not one judging a slot by its spins alone.
