Each fourth fisherman a bonus collects starts a new batch of 10 spins, 12 if +2 SPINS was drawn, at the next collect rate, and this can happen three times. Opening awards of 12 to 22 spins, set by four or five Scatters and by +2 SPINS, are not counted as extensions. At least one new batch came in 19 of the 50 tickets and 26 of the 82 natural bonuses.

How it plays
8 rules screens from the game
Reels five wide and three high pay on 10 fixed lines that start at the leftmost reel; at USD 2.00, the stake used throughout, each line carries a 0.20 coin. Top of the table is the red truck, USD 400 for five, and two trucks already pay USD 1.00, the same as two fisherman Wilds. Below it the fishing rod pays USD 200, a dragonfly or a tackle box USD 100, and the card ranks A to 10 USD 20 or USD 10 for five. Fish pay USD 40 for five as line symbols and also wear a cash label, one of nine steps from 2x to 1000x the bet, which only free spins can collect.
Three Scatters give 10 free spins; a fourth makes it 15 and a fifth 20. A base spin with two Scatters can be rescued by a respin that slides the Scatter reels down one row or by a hook that hauls a reel up to show a third. Up to five modifiers are drawn before the feature begins: extra fish on the reel strips, extra fishermen, a higher chance of dynamite, hooks and bazookas, a start at level 2, and +2 SPINS, which also adds two spins to every later batch.
Only free spins bring the fisherman Wild, who can land on any reel, stands in for all symbols but the Scatter and takes the cash label of each fish in view. Every fourth one collected brings another 10 spins and raises the rate for that batch to 2x, then 3x, then 10x, and after the fourth level no more batches come. Dynamite may drop fish onto a fisherman screen that has none, a hook may lift a fisherman onto a screen of fish, and a bazooka may replace everything but the fishermen.
The 100x BUY FREE SPINS was the one bought, 50 times at USD 200; BUY SUPER FREE SPINS asks 450x and raises the share of 1000x fish. Switching Ante on doubles the bet multiplier to 20x, USD 4.00 on screen, adds Scatters to the strips and locks both buys. Listed RTP is 96.52% in normal play, 96.53% with Ante or the standard buy and 96.51% for the Super version; volatility is high, a normal bet runs from USD 0.10 to USD 250, or up to USD 500 with Ante, and 25,000x ends a round.

Verdict
The best ticket drew no modifiers
Fishermen gathered USD 10,326 of the USD 10,973.80 paid inside the 82 natural free spins rounds, 94.1% of free spins money, and line wins added the other 5.9%. No fish above 25x the bet was ever collected, although fish worth 50x to 1000x appeared 23 times on natural free spins screens.
Natural bonuses that drew no modifier, 25 of them, averaged 49.00x the stake, the seven that drew three averaged 109.53x, and the two with four only 37.40x. Round 8824, top of the series with 444.2x over 48 spins, had MORE FISHERMAN and +2 SPINS, while round 7935, at 222.4x over 40 spins, had none.
Ticket 16 opened with none of the five modifiers, ran to 50 spins and the 10x stage and returned 4.787x its USD 200 price, the best of the 50 purchases. Ticket 41, the only one to draw all five, stopped at 2.6x. Across the set, the 18 tickets without a modifier averaged 0.71x the price and the four with three just 0.40x, so the size of the draw did not rank the bonuses.
- Ticket 16 reached the 10x collect stage without any modifier and returned 4.787x the USD 200 price
- Natural bonus rounds, one per 121.95 spins, brought 62.6% of everything the ordinary series returned
- Seven natural bonuses that drew three modifiers averaged 109.53x the stake
- Fishermen collected 94.1% of the money paid inside natural free spins
- Fish worth 50x to 1000x showed 23 times on natural free spins screens and none was collected
- The two natural bonuses that drew four modifiers averaged 37.40x, under the 49.00x of rounds with none
- MORE DYNAMITES, picked for 21 natural bonuses, came with a 64.91x average, below the 67.65x of rounds without it
- Fifty tickets cost USD 10,000 and returned USD 8,187.60

FAQ
7 questions · answered from the log
Which free spins modifiers did Big Bass Splash 1000 hand out most often?
MORE DYNAMITES came up most, in 21 of the 82 natural bonuses, followed by MORE FISH and START FROM LEVEL 2 with 19 each and MORE FISHERMAN and +2 SPINS with 16 each, while 25 bonuses drew none. Among the 50 purchases MORE FISHERMAN was the most frequent, on 15 tickets, and ticket 41 was the only one with all five.
Spinning normally, how many rounds does a Big Bass Splash 1000 trigger take?
A spacing of 121.95 rounds on average, with 82 natural bonuses across the 10,000 spins. Sixty-five of them began with 10 spins, 16 with 12 because +2 SPINS was drawn and one with 15 from four Scatters; five Scatters never landed.
What pulled the Big Bass Splash 1000 demo down to 87.72% against a 96.52% rating?
For a mean of 10,000 rounds of this game, the approximate 95% CI spans 69.83% to 105.62% and contains the 96.52% rating. Natural bonus rounds paid 62.6% of the series' return, and the biggest of them reached 444.2x, far under the 25,000x cap; without round 8824 the remaining 9,999 rounds returned 83.29%.
Do Big Bass Splash 1000 bonus buys at USD 200 usually pay back the price?
No. Half of the 50 tickets returned USD 103.20 or less, and only 12 covered the USD 200; four went past 2x the price and none reached 5x.
Did a fisherman ever collect a 1000x fish during the Big Bass Splash 1000 test?
No. Five natural free spins showed a 1000x fish, in rounds 3319, 3401, 7935 and 8824, and so did one spin each of tickets 12, 24, 25, 31 and 34, with no fisherman there to take it. The largest value collected was 25x the bet, once in natural play and twice in purchases.
Did any Big Bass Splash 1000 bonus reach the 10x collect, and what does it take?
Yes, natural rounds 8824 and 7935 and ticket 16 did; round 8824 and ticket 16 each collected twice at 10x for USD 280, and round 7935 never collected at that rate. It takes twelve fishermen from a 1x start, because every fourth one adds 10 spins and lifts the collect rate one step, from 1x to 2x, 3x and then 10x.
Are the cash labels on Big Bass Splash 1000 fish paid in the base game?
No. 8,763 of the 10,000 base rounds showed at least one fish value and 98 showed a 1000x one, but outside free spins a fish pays only as a line symbol, USD 40 for five on a USD 2.00 stake. The best base round without free spins was 82x, on round 7168.
