How Big Bass Bonanza 1000 works

Big Bass Bonanza 1000 keeps the layout the fishing series made famous. You play 5 reels and 3 rows with 10 fixed paylines, and wins pay left to right for matching symbols. Tackle boxes, rods, dragonflies and the usual card ranks fill the reels, with fish money symbols mixed in.

The money fish are the point of the game. Each one carries a cash value shown as a multiple of your stake, and in this version the top value is 1,000x. In the base game they are mostly decoration, because the fisherman wild that collects them only appears during free spins. Base game wins come from the paylines and are usually small.

The base game has one extra trick. When two scatters land, the game can randomly reel in a third one to start the bonus. It does not happen often, but it means a two scatter spin is never quite finished until the reels stop.

Stakes start at 10p a spin at UK casinos. The bet range matters less than the risk profile, which we cover below.

Big Bass Bonanza 1000 free spins and bonus features

Three, four or five scatters start the bonus with 10, 15 or 20 free spins. During the round, every fisherman wild that lands collects the value of all fish money symbols on screen. Most of the game's return comes from these collects.

Wilds also count toward a meter. Every fourth wild retriggers the round with 10 more spins and raises the multiplier on collected values: 2x after the first retrigger, 3x after the second and 10x after the third and last one. Reaching the 10x level with a few large fish on screen is how the 20,000x cap becomes possible.

The provider adds random help on top. After a free spin, wilds or money symbols can be dropped onto the grid at random positions, which saves some rounds that would otherwise end empty.

Outside the UK there are two bonus buys. Free spins cost 100x your stake, and super free spins cost 450x with a better chance of the 1,000x fish. An ante bet for 50% more per spin increases the number of scatters on the reels.

Big Bass Bonanza 1000 RTP versions: what to check

The top RTP is 96.51%, and sources list two lower settings at 95.51% and 94.51%. A casino picks one of the three and the game looks identical either way, so the only way to know is to look. Open the game, press the menu or "i" button, and read the rules until you reach the return to player line. That line shows the setting the casino runs.

A one point drop sounds small, but it applies to every spin. Over a long session or a big wagering target, it adds up. Our RTP and volatility guide shows the difference in money.

Max win and volatility in practice

The 20,000x cap is far above what most earlier Big Bass games offer. Most sources rate the game high volatility and OLBG goes one step further to very high. In practice the base game pays little, the bonus can take a long time to arrive, and many free spins rounds end with a handful of small collects.

That shape matters for bonus play. When you have to wager a bonus 30 or 40 times, a game that pays mostly through rare features can wipe out the balance before you finish. A medium risk game gets you through wagering more often, while a game like this gives you a small chance at a large result. Run your numbers in the wagering calculator first. Games with an even bigger cap are on our biggest max win slots list.

Playing Big Bass Bonanza 1000 with free spins or a bonus

Big Bass games appear in free spins offers all the time, and this one will too. Check the terms before you start. The bonus buy and the ante bet are often banned while a bonus is active, and most casinos set a maximum bet per spin until wagering is complete. Using a blocked feature can cost you the winnings.

Our guide to wagering requirements explains how playthrough works, and the free spins page lists current deals. For a casino with a big slot lobby, see our Mostbet review.

Similar slots

The original Big Bass Bonanza uses the same rules with a much smaller cap. Bigger Bass Bonanza adds a fourth row, and Big Bass Splash mixes in random modifiers before the bonus. All of them are listed on our Pragmatic Play slots page.

Our verdict on Big Bass Bonanza 1000

Big Bass Bonanza 1000 is the classic fishing slot with bigger fish. The rules have not changed: collect money symbols with the fisherman and push the multiplier up through retriggers. What has changed is the top fish value of 1,000x and the 20,000x cap, at a 96.51% top RTP. If you already enjoy the series, this is the version with the most upside. If you wanted new mechanics, you will not find them here. Check that your casino runs the 96.51% setting and size your stake for a long wait between bonuses.
