The fisherman is back for Helloween again this year

When fall arrives, Pragmatic Play reliably pulls out the fishing rod. Seasonal editions have followed every year since Big Bass Helloween first came out, and “Big Bass Halloween Splash 1000,” unveiled on October 12, is the fourth in that line. This time the series’ face, the fisherman, shows up with fangs. Development is by Reel Kingdom, which has handled the Big Bass series from the start.

The 1000 at the end of the name is a familiar formula by now. As with Big Bass Bonanza 1000 and Big Bass Splash 1000, it means a single fish can be worth up to 1,000x your bet. Within the Helloween series alone, the max win has risen to 20,000x for the first time. The cap of the previous game, Big Bass Halloween 3, was 5,000x, so this is four times higher.

The reel structure is unchanged: 5 reels, 3 rows, 10 paylines. The high-paying symbols have changed to Helloween props like a fishing rod, a bat and a coffin-shaped treasure chest, while card symbols from 10 to A handle the low-paying slots. If you have played the series even once, you can jump right in without any explanation of the rules. What’s new isn’t the rules, it’s what hides inside the bonus.

The door to the bonus is wider than you’d think

Land 3 fang-fish scatters to start 10 free spins, 4 for 15, and 5 for 20. That much is ordinary. What’s worth noting is when the scatters stop at 2. In that case, more scatters can be pulled onto the screen at random, opening the bonus. A narrowly missed spin doesn’t just end there.

According to the figures Pragmatic Play disclosed in the media pack, free spins trigger on average once every 111 spins. That is a low threshold even within the series. Turning on the extra-chance option that costs 1.5x your bet raises this frequency further, and if you don’t want to wait, you can buy the bonus directly for 100x your bet.

One pumpkin changes the bonus

The first thing that catches your eye in this game is the pumpkins. Right before free spins start, six pumpkins are laid out on the screen and you pick them one at a time to open. There are five possible upgrades inside. Wilds appear more often, more fish with values land, or the number of free spins increases. There is also an upgrade that starts you with a 2x multiplier from the beginning, and one that makes the random feature described below trigger more often.

The catch is that this choice is purely luck. Even with the same 10 free spins, the round becomes a completely different game depending on which pumpkin you opened. 10 spins that start with a multiplier upgrade and 10 spins where you found nothing differ in expected value from the very start. That is why the bonus in this game inevitably feels like it has a wide spread of results.

Fortunately, you don’t get just one shot. Even during the bonus, if a pumpkin symbol lands on reel 5, one more upgrade is added for the remaining rounds. Even if the start was disappointing, there is still room to make up ground along the way.

The multiplier climbs to 10x over three steps

The formula inside free spins is pure Big Bass. When a fisherman wild lands, he collects the values of all fish money symbols that dropped on the same spin. A single fish is worth up to 1,000x your bet.

Every time you collect four fishermen, 10 more free spins are added, and the win multiplier rises with them. It is 2x on the first retrigger, 3x on the second, and 10x on the third and final retrigger. The last step from 3x to 10x is especially steep, and the 20,000x max win effectively comes from this stretch.

There is also a feature that rescues missed spins. When a fisherman shows up with no fish, or fish show up with no fisherman, one of three special features triggers at random to fill in the missing piece. One of the pumpkin upgrades raises the chance of this feature triggering.

The 33rd since December 2020

Big Bass began with Big Bass Bonanza, released in December 2020. It was an ordinary fishing slot with a max win of 2,100x. Nobody at the time knew it would become a star earner for Pragmatic Play. Counting only the games with Big Bass in the name on AI Slot, this release is the thirty-third.

For almost six years, around five games have come out every year. A summer splash in 2022, a Hold & Spinner in 2023, a racetrack and the Amazon in 2024, and a boxing ring and dice in 2025. The setting kept changing, but the basic framework of the angler collecting the fish payouts never did. That is why fans skip the rules explanation every time a new one comes out.

The flow changed sharply with Big Bass Bonanza 1000 in April 2025. Raising the fish value cap to 1,000x pushed the max win up to 20,000x. In December of the same year, Big Bass Splash 1000 hit 25,000x, and this September Big Bass Vegas 1000 and then this October’s Helloween edition joined the 1000 line in turn.

By the numbers, it’s a pretty honest game

The media pack lists hit frequencies in quite some detail. These are averages, so actual results can run much longer or shorter, but they are enough to get a sense of the game’s character.

Wins themselves come often, roughly once every seven spins. On the other hand, 1,000x or more happens about once in 70,000 spins, and results above 5,000x come about once in 3 million spins. The 20,000x cap catches the eye, but that number isn’t what really drives this game. The focus is on entering free spins often and how long you can keep the retriggers going inside them. That is also why the volatility is classed as medium rather than high.

The base RTP is 96.50%. However, 95.50% or 94.50% versions may be offered depending on the operator, so the conditions can differ even for the same game. The top bonus buy costs 450x your bet and starts the free spins from a better position.

Buy the bonus or wait?

Running the numbers in the demo gives an interesting comparison. Free spins arrive on average once every 111 spins. If you bet 1 and wait, you spend an average of 111 before you meet the bonus. The bonus buy price is 100. On the numbers alone, buying is very slightly cheaper.

But the 111 spins you wait through do not vanish for nothing. The base game wins once every 7.42 spins, so about fifteen hits land while you wait. Scenes of fish money symbols landing in the base game also show up fairly often. Buying skips this whole process, and in return you stake 100x on a single bonus at once.

The 450x top buy is a different story again. Pragmatic Play only says it starts from a better position, but in most 1000 series games the top buy opens the bonus in an enhanced state. At the same 450, you could make four and a half regular buys. Since no real money is spent in the free demo, you can buy each in turn and compare for yourself how different the bonus feels.

Multiplying the max bet of 250 by the 20,000x max win gives 5 million. The max payout limit that Pragmatic Play lists in the media pack is exactly 5,000,000 as well. The bet unit works by multiplying 10 paylines by the coin value, so pressing the bet button on the demo screen shows finely divided steps from 0.1 up to 250.

Its place within the Helloween series

Line up the four games side by side and the trend shows. The first had a cap of 2,100x, and it rose to 5,000x with part 2 and part 3. This one jumps all the way up to 20,000x. RTP has stayed in the mid-96% range throughout the series.

For a game with a seasonal name, the content is fairly aggressive. This is not a repackage that just swaps in Helloween clothing. This is the first time the multiplier structure of the 1000 series has come to the Helloween line. It’s also fun to compare it with Big Bass Vegas 1000, released around the same time. Both use the 1000 formula, but in the Vegas game two fishermen split the meter filling, so the bonus has a different feel.

If you like Big Bass, there is little reason to hesitate over this one. The rules are familiar, and the new pumpkin upgrades make every bonus a slightly different round.
