Fishermen, not Scatters, extend the round: every fourth one collected adds 10 spins, or 12 with +2 SPINS, until x10 is reached. Bonuses whose spin count grew after the opening award were 25 of 89 natural and 11 of 50 bought; 12-spin starts from +2 SPINS and 15-spin starts from four Scatters are opening awards and are not counted.

How it plays
7 rules screens from the game
Lines pay left to right, 10 of them fixed on a 5x3 board, starting at reel 1. Santa's snowplow pays most, 200x the total bet for five in a row, and no other symbol pays for a pair; below it sit the rod, the dragonfly, the tackle box, the fish, then A, K, Q, J and 10. The bet menu spans USD 0.10 to USD 375.00.
Every fish symbol carries a cash tag somewhere between 2x and 5,000x the total bet, and the tags only count once free spins are running. Then the fisherman Wild appears on the reels and sweeps up every tag in view. Four fishermen in the bag add 10 spins and raise the collect rate to x2, the next four to x3, the four after that to x10, and no spins are added past that point.
The bonus asks for three Scatters and gives 10 spins for them, with 15 spins for four Scatters and 20 for five. A spin stuck on two Scatters can still be rescued: the reels holding them may slide one row down for a respin of the rest, or a hook may lift a reel to show a third. An ice-fishing scene before the round then draws anywhere from none to five modifiers, START FROM LEVEL 2, +2 SPINS on the opening award and on each extension, MORE FISH, MORE FISHERMAN, and a raised chance of dynamite, hooks and bazookas.
Three helpers may act at the end of a free spin: a hook hauls fishermen onto a screen of fish with nobody to collect them, while dynamite or a bazooka reworks a screen where a fisherman waits without fish. Switching on the higher-chance option sets the bet multiplier at 15x instead of 10x, puts extra Scatter symbols on the strips, and greys out BUY FREE SPINS, which otherwise sells the round for 100x the bet. Volatility is rated high, regular play, the option and the purchase all carry 96.71% RTP, and a round is closed at 5,000x.

Verdict
Grey modifier icons on most tickets
An ice-fishing line drops before every free spins round, and across the ordinary series at USD 2.00 it hooked at least one modifier for 68 of the 89 natural bonuses. Purchases drew far fewer, with a lit icon on 19 tickets out of 50 bought at USD 200. Four of the five cards each lit in 22 to 25 natural bonuses but in only 5 or 6 purchases, and START FROM LEVEL 2 was the nearest pair at 26 against 11.
Natural bonuses with a lit icon, 68 of them, averaged 78.44x the stake at a median of 48.5x, the 21 plain ones 45.30x at a median of 22.4x. Rounds that drew something therefore paid 84.87% of natural bonus money. START FROM LEVEL 2, which has every fish collected at x2 from the first spin, was among the draws of the two largest rounds, 5272 and 6415.
Among the 50 purchases, the 19 tickets with a lit icon had a median of 0.352x the price against 0.28x for the 31 plain ones. So most tickets fell into the weaker of the two groups, while most natural bonuses fell into the stronger.
- +2 SPINS came with 25 natural bonuses, and those rounds averaged 104.31x the stake
- A respin from two Scatters produced 47 of the 89 natural triggers
- Both natural bonuses that reached the x10 collect stage paid more than 390x the stake
- Ticket 29 paid USD 5.00 on its USD 200 price, 0.025x
- Rounds 4716 and 7144 drew all five modifiers and still averaged only 77.5x the stake
- MORE FISH came with 22 natural bonuses, which averaged 69.85x the stake, no more than the 70.87x of those without it

FAQ
7 questions · answered from the log
Before Big Bass Christmas Bash free spins begin, which modifiers can the ice-fishing draw give?
Five cards are in the draw. START FROM LEVEL 2 came with 26 of the 89 natural bonuses, +2 SPINS with 25, the dynamite, hook and bazooka card with 24, MORE FISH and MORE FISHERMAN with 22 each. A single modifier was the most common draw, 41 times, and all five arrived together twice.
How near the listed 96.71% RTP did 10,000 Big Bass Christmas Bash demo spins land?
Very close, at 96.59%: a USD 2.00 stake over 10,000 spins put in USD 20,000 and got USD 19,318.80 back. A single bonus shifts a sample like this a lot, so the approximate 95% CI is wide, 76.69% to 116.5%, and leaving out the one best round brings the other 9,999 down to 91.78%.
Do two Scatters in the Big Bass Christmas Bash base game ever turn into free spins?
Yes, the respin got there 47 times. It started in 276 ordinary rounds, sliding the Scatter reels one row down while the other reels spun again, and the remaining 229 ended without a third Scatter. Three Scatters landing at once gave 41 triggers, and a hook adding the third gave one.
Big Bass Christmas Bash bonus buy at 100x: what did 50 tickets return?
Together they returned USD 6,545.20 for USD 10,000, or 65.45%. The median ticket came to 0.303x, USD 60.60, 42 of the 50 ended under the price, and ticket 23 led with USD 1,460.40 from 40 spins, 7.302x.
Did any Big Bass Christmas Bash round get near the 5,000x max win?
No. Round 5272 topped the series at 482.6x the stake, USD 965.20, after 30 free spins in which 12 fishermen reached the x10 stage. The best base-game spin paid 100x, in round 4381, and a 5,000x fish appeared on one natural free spin, round 6926, with no fisherman to collect it.
What changes in Big Bass Christmas Bash when the BET USD 3.00 higher chance option is on?
The bet multiplier rises to 15x from 10x, extra Scatters go onto the reels and BUY FREE SPINS is switched off; RTP is listed at 96.71% either way. The toggle stayed OFF for every ordinary round and every purchase of the series.
In Big Bass Christmas Bash free spins, how many hooks, dynamite drops and bazookas came up?
Across the 89 natural bonuses the log holds 35 such events: 18 bazookas, 11 hooks and 6 dynamite drops. The 24 bonuses drawn with the dynamite, hook and bazooka card accounted for 18 of them, the other 65 bonuses for 17.
