Christmas Big Bass Bonanza counts a retrigger at the fourth, eighth and twelfth Santa collected during a feature, each worth another ten spins; the starting award of 10, 15 or 20 spins is left out. At least one extension came in 31 of 84 natural features and 16 of 50 tickets in run one, 37 and 26 retriggers in all, and in 32 of 92 natural features and 15 of 50 tickets in run two, 36 and 27 retriggers.

Thirty free spins from a USD 200 purchase, two retriggers and USD 273 at the end · Recorded in a separate browser session, outside the statistical samples.

One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 114 ordinary rounds in this sample. Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

How it plays

6 rules screens from the game

Ten paylines are fixed on a 5x3 grid, paying on adjacent reels counted from the left. The Christmas bauble tops the table at USD 400 for five on a line at the USD 2 stake and still pays USD 1 for a pair; rod, sleigh and tackle box follow at USD 200, USD 100 and USD 100, the fish at USD 40, and A through 10 close the list at USD 20 each. Nothing cascades, so every spin is settled once.

The Santa-hat bass is the Scatter: three anywhere start ten free spins, four give fifteen and five give twenty. Fish carry values of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 2,000x the total bet, and in the base game they pay only as ordinary symbols. Santa is the Wild and appears only inside the feature, where every Santa on screen collects every money value showing at that moment, the job a fisherman does in other Big Bass editions.

Each Santa is kept on a bar above the reels. The fourth, eighth and twelfth Santa each add ten further spins, played after the current batch, and in those added spins the collected values are multiplied by 2x, then 3x, then 10x; once the third retrigger has come, the bar stops. The bought feature costs 100x the stake, USD 200 here, and lands at least three Scatters; in the two logged runs 46 and then 47 of the 50 tickets opened with ten spins, three and then one with fifteen, one and then two with twenty.

Declared RTP is 96.71% for both the ordinary game and the purchase, the rules page calls the volatility medium, wins are capped at 2,100x the bet, and the stake can be set anywhere from USD 0.10 up to USD 250.

Verdict

Thirty-one fish, no Santa

At USD 2 a spin, Christmas Big Bass Bonanza has returned 96.03% and 103.61% over two demo runs, 99.82% pooled over 20,000 spins and 35.5 bets under even money, the rules saying 96.71%, and the 2,000x fish is still waiting for its Santa: it surfaced 13 times in the first run and 18 in the second, 24 of those inside free spins, and on none of those spins was a Santa on the reels. Everything the free spins paid came through Santa all the same, 94.0% and then 94.7% of USD 11,732 and USD 12,179, and in neither run did a natural feature reach the 10x stage: the collections split USD 6,832, USD 3,396 and USD 804 across 1x, 2x and 3x in run one and USD 8,186, USD 3,188 and USD 162 in run two.

The features came 176 times over the two runs, 84 and then 92, one per 113.6 spins or 8.8 bHz, and paid 68.11x the stake on average, 49.75x at the median, 60.0% of everything returned; 34 cleared 100x, only four stayed under 20x, and in both runs a feature's length set its worth: those that stopped at ten spins averaged 45.3x and then 36.8x, those that reached twenty 82.9x and 112.7x, and those that ran to thirty 240.1x and 149.9x. Run one's round 7742 remains the largest at 359x over thirty spins; run two's best was 279.5x on round 6394 from twenty, USD 308 of it on one Santa collection, and 63 of the 176 features retriggered at least once, 73 retriggers in all.

The USD 200 ticket came back at 0.8411x of price over 100 buys, 0.989x and then 0.6932x, but 81 tickets missed their price and the median came in at USD 67; the whole sample leans on five 40-spin tickets, two in run one and three in run two, which took 45.6% and 32.9% of each run's bought money, ticket 20 of run one at USD 3,492 and run two's ticket 9 at USD 1,304 the largest. A base spin paid on 12.92% and 13.86% of spins, the longest droughts were 67 and 57 spins, the best base spins 72x on round 8549 and 200.5x on round 4004, and the balance closed 397 bets down and then 361.5 up, the pooled low of 1,053.5 bets sitting at spin 2866 of run two.

Measured upsides
  • Thirty-four of 176 features cleared 100x, led by 359x on round 7742 of run one
  • One feature per 113.6 spins across 20,000, 8.8 bHz, 60.0% of the return
  • Run two ended 361.5 bets ahead, 103.61%, above its start on 4,633 spins
  • Santa collected 94.0% and 94.7% of the free spins money, USD 11,536 in run two from 262 collections
Measured downsides
  • Thirty-one sightings of the 2,000x fish across two runs, none with a Santa on the reels
  • Eighty-one tickets of 100 missed the USD 200 price, the median at USD 67
  • No natural feature in 176 reached the 10x stage; only bought tickets did, five of them
  • Sixty-five of 100 tickets stopped at ten spins and averaged 0.201x and then 0.264x of their price
Verdict by run · 2 runs · tap a run to read it
Run 01·2026-09-26·96.03% The 2,000x fish, the largest value printed in the rules, surfaced 13 times: twice in the base game, nine times in natural free spins and twice in bought ones.

The 2,000x fish, the largest value printed in the rules, surfaced 13 times: twice in the base game, nine times in natural free spins and twice in bought ones. On none of those spins was a Santa on the reels to collect it. What the features did pay came through Santa: 94.0% of the USD 11,732 won inside natural free spins arrived through his collections and 6.0% through paylines.

The 51 features that ended at ten spins averaged 45.3x, the 23 that ended at twenty 82.9x, and the six that ran to thirty 240.1x, among them the best round of the run, 359x at round 7742. No natural feature got to the fourth stage with the 10x multiplier; of the money Santa collected in natural features, 30.8% came at 2x and 7.3% at 3x.

Purchases, fifty of them at USD 200, averaged 0.989x the price, but ticket #20 supplied USD 3,492 of that after three retriggers; the 31 tickets that stopped at ten spins returned 0.201x on average, the eight that reached twenty 0.704x and the six at thirty 2.373x. The two tickets that reached forty spins took 45.6% of all purchased money between them.

The base spin itself paid on 12.17% of spins, the best base hit was 72x at round 8549, and the balance sat 798.5 bets below its start at round 7698. The 84 natural features supplied 61.2% of all payouts in the ordinary series.

Run 02·2026-09-30·103.61% Eighteen times a 2,000x fish surfaced, six in the base game where it pays as an ordinary symbol, eleven in natural free spins and once in a bought feature, and on none of those twelve feature spins was a Santa there to collect it; the fish that did get collected came through 262 Santa collections worth USD 11,536, 94.7% of the USD 12,179 the 92 natural features paid in free spins, with paylines adding USD 643.

Eighteen times a 2,000x fish surfaced, six in the base game where it pays as an ordinary symbol, eleven in natural free spins and once in a bought feature, and on none of those twelve feature spins was a Santa there to collect it; the fish that did get collected came through 262 Santa collections worth USD 11,536, 94.7% of the USD 12,179 the 92 natural features paid in free spins, with paylines adding USD 643. The stage ladder stayed short: Santa collected USD 8,186 in the opening ten spins at 1x, USD 3,188 at 2x after a first retrigger and USD 162 at 3x, and no natural feature reached the 10x stage; 32 features retriggered, 36 times in all, with the 25 that ran to twenty spins averaging 112.7x and the seven that reached 25 or 30 spins 153.9x against 36.8x for the 58 that stopped at ten.

Ninety-two features came one per 108.7 spins, 9.2 bHz, and paid 66.39x on average with a 44.5x median, 58.9% of the return, 19 of them past 100x and two under 20x; round 6394 led at 279.5x from twenty spins, USD 308 of it on the eighteenth, ahead of round 8572's 263.5x over thirty spins and round 9022's 242x, and the longest wait ran 665 spins after round 9165. The fifty USD 200 tickets brought back USD 6,932, 0.6932x of price: 34 stopped at ten spins and averaged 0.264x, the eight that reached thirty 1.472x, and the three that ran to forty, tickets 9, 43 and 10, paid USD 1,304, USD 610 and USD 364, 32.9% of the ticket money between them; 40 tickets stayed under the price with USD 71 the median and USD 4 for ticket 34, and Santa collected 93.4% of the bought money, USD 528 of it at the 10x stage, which only the bought features reached.

A base spin paid on 13.86% of spins at a 2x median, 8,614 spins returned nothing, twenty droughts reached 30 spins and the longest ran 57 from round 1181; the best base spin, 200.5x on round 4004, was USD 401 from paylines alone, with 128x on round 2999 and 102x on round 1172 behind it. Spin 379 put the balance ahead for the first time; it bottomed 656.5 bets down on spin 2866, then climbed to 684.5 bets up on spin 9165 and closed 361.5 ahead, 103.61% of the stake, above its start on 4,633 spins including the last; the 2,000-spin blocks returned 84.5%, 101.2%, 113.9%, 97.3% and 121.2%.

No. Santa never shared a feature spin with it: the 2,000x fish surfaced 13 times in run one and 18 the next across 20,000 spins, 6 of the latter in the base game, where it pays as an ordinary symbol, and 12 in features. The most a single collection paid in run two was USD 308, on the eighteenth spin of round 6394.

What went wrong with the USD 200 buy in run two?
Lab answer

Fewer long tickets: run one had two 40-spin tickets worth 45.6% of its bought money, including ticket 20 at USD 3,492 after three retriggers; run two had three, tickets 9, 43 and 10, worth 32.9%, the best USD 1,304. Ten-spin tickets, 31 and then 34 of 50, averaged 0.201x and 0.264x, and over 100 tickets 81 came back below the price.

Does the retrigger multiplier ever reach 10x?
Lab answer

Yes. Forty-spin tickets got there five times, two in run one and three in run two, the latter collecting USD 528 at the 10x stage, while none of the 176 natural features reached it. In natural features Santa collected USD 8,186 at 1x, USD 3,188 at 2x and USD 162 at 3x in run two, after USD 6,832, USD 3,396 and USD 804 in run one.

Ten, twenty or thirty spins, what is the difference?
Lab answer

The 58 features of run two that stopped at ten spins averaged 36.8x, the 25 that reached twenty 112.7x, the three at 25 spins 159.3x and the four at thirty 149.9x; in run one the same bands averaged 45.3x, 82.9x and 240.1x. Sixty-three of 176 features retriggered at least once, 73 retriggers in all.

Is the base game any different the second time?
Lab answer

No, not much: 13.86% of spins paid after 12.92%, at a 2x median both times, while droughts reached 57 spins after 67. The best base spin rose from 72x on round 8549 to 200.5x on round 4004, USD 401 from paylines alone, and the balance closed 361.5 bets ahead after 397 down.
