Bigger Bass Bonanza Free Demo: The Extra Row, the 12 Lines, and the 4,000x Fish

Bigger Bass Bonanza is the first sequel in the fishing series and the sensible one: a fourth row, a reported 12 paylines instead of 10, and money symbols that reach 4,000x in the bonus, all running the same wild-collect free spins as the original. Almost nothing about the bonus structure is new. The canvas it plays out on is what changed, and the demo is the cheapest place to find out whether that suits you.

How the game works

The credit line is the first thing to sort out. This is a Reel Kingdom game, the studio Pragmatic Play partners with and distributes for, which is why searching lobbies for “Pragmatic” sometimes fails to surface it while searching the game name works fine. The maths, the art, and the series belong to Reel Kingdom; Pragmatic Play puts it in front of casinos.

Pragmatic Play’s own game page describes it as a 4x5 edition of the classic fishing slot: five reels, four rows. Slot databases put the line count at 12 paylines, up from the original’s 10, and because each line still costs a cent, the minimum spin is reported at 0.12 rather than 0.10. That is a small number with a real consequence, since low-stakes players who ration by the spin get slightly fewer spins per deposit here.

Everything else in the base game is franchise-standard: fish that pay like ordinary symbols until the bonus turns them into money symbols, and a base game whose only real job is to land three, four, or five scatters for 10, 15, or 20 free spins.

The wilds, the money fish, and the 10x retrigger

Inside the bonus, wild symbols collect all visible money symbols, so the value of a wild landing depends entirely on how crowded the screen is when it arrives. Pragmatic Play states that money symbols carrying values up to 4,000x can land in the bonus game, which is where the headline number comes from.

The retrigger ladder is confirmed on the provider’s page and is worth reading precisely: every fourth wild awards 10 additional spins and a progressive win multiplier of 2x, then 3x, then a final 10x. Four wilds is not a free ride, and by that same description the top rung takes twelve of them inside a single round. Most bonuses end one or two rungs down, which is the honest shape of this game and something a long demo session shows faster than any paytable does.

Bigger or original: what actually changed

Three letters separate the two names, and plenty of players end up reading about the wrong game, so here it is in plain terms.

Big Bass Bonanza (2020) is the lean version: 5x3, 10 paylines, a max win reported at 2,100x, and a minimum stake reported at 0.10. Bigger Bass Bonanza (reported as a September 2021 release) keeps the identical collect-and-retrigger engine but stretches the grid to four rows, adds two paylines, and raises the money-symbol ceiling to 4,000x. Because more fish fit on screen at once, a well-timed wild can collect a fatter pile here than the original ever offers, and the swings widen to match. Databases disagree about how much: some rate this one a full 5/5 for volatility against the original’s 4/5, others still call it medium-high.

If you want the same engine with pre-bonus modifiers layered on top instead of a bigger grid, that is Big Bass Splash, whose ceiling is reported at 5,000x. Three games, one collect mechanic, three different textures. The RTP default is 96.71% across all three, so the choice is about variance, not value.

RTP honesty check

Pragmatic Play publishes 96.71% as the default for Bigger Bass Bonanza, and that is genuinely strong for a mainstream slot. Two warnings sit behind that number.

First, the default is not what every casino runs. The Big Bass games are widely reported to ship to operators in more than one RTP build, and the operator, not you, picks which one goes in the lobby. Reduced versions are documented elsewhere in the series; for this specific title the provider publishes no lower figures at all, which means the only reliable way to know what you are playing is the game’s own info panel at the casino you are on. If the number printed there is below 96.71%, you are on a reduced build of the same game.

Second, RTP says nothing about a single session. On a slot this bonus-dependent, the return is packed into rare free-spin rounds, so a 96.71% game can still empty a bankroll in an evening. Our RTP guide explains what the figure does and does not promise.

The demo above runs the default build with play money, which is exactly why it is a poor guide to what your casino has loaded. Learn the mechanic here, verify the percentage there.

The bottom line

Bigger Bass Bonanza earns its name honestly: bigger grid, bigger lines count, bigger fish, same fisherman doing the same job. It is a better fit than the original for players who want more money symbols in view when a wild lands, and a worse fit for anyone counting spins at the lowest stake, where the 0.12 minimum quietly bites.

Learn the retrigger rhythm in the demo, notice how many bonuses stall before the 10x rung, confirm your casino runs the 96.71% build, and size real bets for the rounds where the wilds never show up.

When you are ready for real bets, pick the casino by its payout record, not its bonus size - our honest casino reviews rank sites on exactly that.
