Big Bass Halloween Splash 1000 slot by Pragmatic Play

By the CasinoDemo editorial team · Updated 2026-11-09 · How we review

Big Bass Halloween Splash 1000 is a Reel Kingdom slot from Pragmatic Play that puts a vampire fisherman, bats, coffins and skeleton fish on a 5x3 grid with 10 paylines. Underneath the costume it is a Big Bass game: fish carry cash values, Fisherman Wilds collect them in free spins, and every fourth Wild pushes the collection multiplier up to 2x, 3x and finally 10x.

We read all eight rules pages in the free demo and bought both bonus options at a $2 bet with the Ante Bet off. One buy paid $1,632, the other $126.60. Here is how it all works, with the real numbers from our screens.

How the game works

The reels are 5 wide and 3 high, with 10 fixed paylines. All symbols pay from left to right on adjacent reels starting from the leftmost reel. Only the highest win is paid per combination on a payline, and wins on different lines are added together.

At a $2 bet, the paytable shows the monster truck paying $400 for five, $40 for four, $10 for three and $1 for two. The bat pays $200 for five, the fishing rod and the coffin pay $100 each, and five money fish pay $40. A and K pay $20 for five, while Q, J and 10 pay $10. Three of any card symbol pay $0.40.

Special symbols: Fisherman Wild, Scatter and Money fish

The Fisherman Wild appears on all reels, but only during free spins. It substitutes for every symbol except the Scatter and the Money symbols. The skeleton fish Scatter appears on all reels.

Money symbols are the fish. On every spin they take a random value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 1000x the base bet, and that cash can be won during free spins. The 1000x fish is the one the game is named after, and our screens did catch a $2,000 fish at a $2 bet.

In the base game, whenever two Scatters land they are collected in the cauldron beside the reels, and randomly the free spins can trigger from that. When two Scatters land without a third, a random feature may either respin the reels with the Scatters moved down one position, or drop one more Scatter onto the screen.

Free spins, levels and retriggers

Three, four or five Scatters award 10, 15 or 20 free spins. During the regular free spins, each Fisherman Wild collects the values of all Money symbols on the screen. Every Wild that lands is also collected for the rest of the round.

Every fourth Wild collected retriggers the feature with 10 more free spins and raises the Money collection multiplier: 2x on the second level, 3x on the third and 10x on the fourth. Retriggered spins are played after the current batch ends, and the multiplier applies to them. After the fourth level the feature cannot retrigger again.

Three random modifiers can also fire at the end of a free spin. With fish but no fisherman, spiders pull reels up to bring fishermen in. With fishermen but no fish, Money fish can appear through the trick or treat spin, or a bazooka can change every symbol except the fishermen.

Pick a pumpkin upgrades

Before the free spins start, you pick one of six pumpkins. It reveals an upgrade or no reward. The possible upgrades are:

More Fishermen: more Wilds on the reel strips. Start From Level 2: the round begins on the second level. More Fish: more fish symbols on the reel strips. More Treats: higher chance of the trick or treat, spider or bazooka features. +2 Spins: 2 more free spins at the start and 2 more on every retrigger.

The Pumpkin symbol can also land randomly on reel 5 during free spins and open a new pick. A revealed upgrade starts on the next spin and guarantees at least 5 more free spins at the current level.

Bonus buy options and our demo results

The Buy Feature menu offers two options. Buy Free Spins costs 100x the base bet ($200 at $2). Buy Super Free Spins costs 450x ($900 at $2) and increases the chance of Money symbols worth 1000x the base bet. The rules list a 96.50% RTP for both buys.

Our Free Spins buy landed five Scatters for 20 spins. The first pumpkin gave More Fish, and a later pumpkin on reel 5 added +2 Spins, so retriggers became 12 spins. We reached level 2, then level 3, and finally the 10x level. One spin there had a x10 fisherman collecting $580 on its own. The round ended at $1,632 over 63 free spins, about 816x the bet and roughly eight times the $200 cost.

The Super Free Spins buy landed four Scatters for 15 spins and opened with a Super Fish screen. After that the round was quiet. We reached level 2 and finished with $126.60 over 27 spins, about 63x the bet and well short of the $900 cost. Both are single rounds and tell you nothing about averages, but they show the spread.

Ante Bet, RTP, max win and bet range

The Ante Bet changes the bet multiplier from 10x to 15x, so a $2 bet becomes $3. It adds more Scatter symbols to the reels for a higher chance of triggering free spins, and it disables the Buy Free Spins feature.

The theoretical RTP is 96.50%, and the rules show the same figure with the Ante Bet, with Buy Free Spins and with Buy Super Free Spins. The game is rated medium volatility. The max win is capped at 20,000x the bet. If a free spins round reaches it, the round ends at once and the remaining spins are forfeited. The game's data puts the odds of the top win at about 1 in 3,212,978. Bets in the demo ran from $0.10 to $375.

Our verdict

Big Bass Halloween Splash 1000 keeps the Big Bass formula and adds two good ideas: the pumpkin upgrades and the 1000x fish. The pumpkin pick changes how a round plays, and reaching the 10x level with big fish on screen is where the money is. Our two buys showed both sides: 816x on the cheaper buy, 63x on the 450x Super buy. The 96.50% RTP is the same in every mode, so the buys only change how fast you swing. Try both in the demo before you pay for one.
