Three Bonus Scatters on an ordinary USD 1.00 spin open 10 Cash Spins with four upgrades lit; a Lock & Spin collect on spin 6 takes PAID to USD 20.50, the meter reaches x2 on spin 10 and adds five spins, a USD 14.00 collect on spin 12 lifts PAID to USD 34.50, and the CONGRATULATIONS card shows USD 40.90 after spin 15. Recorded in a separate browser session, outside the statistical samples.

Across the whole run the 46 natural bonuses split into 1 under 20x, 36 between 20x and 50x, 9 between 50x and 100x and 0 at 100x or more, and together they made up 22% of everything the game returned. The wait between two triggers ran from 1 to 862 spins. Payout figures here cover the whole bonus round in ordinary stakes, the trigger spin included: its scatter pays and line wins count towards the bonus.

Inside Cash Spins every third Collect symbol completes a meter step that adds five spins and raises the cash collect multiplier, from x2 up to x10. Counted as extended are bonuses that gained spins this way after the first spin, 35 of 46 natural ones; spins that Pick a Fish adds before the start belong to the opening award.

Up to 4,096 ways are open on a board of six reels and four rows; any symbol pays when it covers neighbouring reels in a row beginning at the first, and only the highest win of each combination is paid. With USD 1.00 staked, six Boats are worth 5.00, six Floats or Fishing Rods 2.50 and six Tackle Boxes or Dragonflies 2.00, and these five symbols already pay for two of a kind. A and K reach 1.50 for six, Q and J 1.20, 10 and 9 1.00. The lifebuoy Wild appears only on reels 2 to 6 and stands in for anything other than the Bonus Scatter, the Collect Scatter and the cash prize fish.

Fish with cash amounts can land on any reel, but they pay only when a Collect Scatter lands in the first or last column during that spin, expanding to award every amount in view. Each Collect Scatter win opens the next badge on the left panel, in the order Dual Collect, Lock & Spin, Cash Boost, Pick a Fish and Big Splash. According to the rules, unlocked upgrades remain active in the main game and in Cash Spins where they apply.

Cash Spins begin with 10 spins for three Bonus Scatters, while four, five or six add 20x, 100x or 500x the bet on top. Collect symbols gathered during Cash Spins fill a meter whose steps each add five spins and a cash collect multiplier, x2 first and then x3, x5 and x10. Big Splash Cash Spins open on a Pick a Fish screen, where the fish picked reveal upgrades active for that bonus only.

Version 1.7.0.0F, the build tested, is set to 95% RTP, and one game can pay at most x10,000 the total bet. USD 25.00 is the largest stake and USD 0.10 the smallest, and the demo offers no bonus buy.

Verdict

Rounds with every upgrade lit

Cash Collect awards paid USD 3,359.50 in 454 rounds that had no bonus, 35.69% of everything the 10,000 ordinary rounds returned, while the 46 natural bonuses, with their trigger spins, added 22.35%. Round 3997 shows how far a single collection went: one Collect Scatter on reel 6 took 57x the stake, 50x of it from a Pick a Fish symbol and 7x from three cash fish. The largest win without a bonus, 72x in round 9306, was a ways win with no collector involved.

All 36 bonuses that opened with Pick a Fish were Big Splash Cash Spins, and they averaged 45.63x the stake against 46.06x for the ten plain Cash Spins triggered with two to four upgrades lit. Inside the feature the collect meter ended at x2 in 33 bonuses and at x3 in four, and it never reached x5. Every natural bonus except round 9059 paid at least 31.5x; that one played 12 Big Splash spins without a win and kept the USD 0.40 of its trigger spin.

With all five upgrades unlocked, 5,835 rounds returned 102.31% of their stake, and the 4,165 played at four upgrades or fewer returned 82.66%. Nearly all of the gap came from bonuses, 36 of them at 6.2 per 1,000 rounds at the top level against 10 at 2.4 per 1,000 below it, while rounds without a bonus returned 74.16% and 71.60%. Both parts are small samples, and every session first played a median of 220.5 rounds below the top level.

Measured upsides
  • Half of the 46 natural bonuses paid 43.5x the stake or more, counting the trigger spin.
  • Cash Collect awards outside the bonus brought USD 3,359.50 over 454 rounds, 35.69% of all series payouts.
  • Four natural triggers had four Bonus Scatters, and with the 20x Scatter prize inside those rounds paid 57.3x to 67.1x.
  • The best natural round, 989, paid 94x over 20 Big Splash Cash Spins with the meter at x3.
Measured downsides
  • Round 9059 played 12 Big Splash Cash Spins without a single win and finished at 0.4x, the pay of its trigger spin.
  • Across 46 natural bonuses the collect meter never passed x3, and nine of them never left x1.
  • Round 3943 ended a drought of 861 rounds without a natural bonus, counted from round 3081

FAQ

6 questions · answered from the log
Do the upgrades in Big Catch Even Bigger Bass stay unlocked between spins?
Lab answer

Yes, each badge stays lit from the Collect Scatter win that opens it until the demo session ends. Every new session started with all five crossed out, and over the 18 sessions of this test all five were unlocked again after a median of 220.5 rounds, 65 at the quickest and 517 at the slowest; two short sessions closed before reaching it.

Does a 94.13% demo result fit the 95% RTP of Big Catch Even Bigger Bass?
Lab answer

Yes, it stays within ordinary sampling spread. Ordinary USD 1.00 spins paid back USD 9,412.80 on USD 10,000 staked, and the approximate 95% CI drawn around that 94.13% mean reaches from 85.39% to 102.86%, a range that contains the 95% set in the game rules.

On their own, how often do Big Catch Even Bigger Bass Cash Spins trigger?
Lab answer

Forty-six triggers came in 10,000 rounds, on average one per 217.4 rounds, 42 of them with three Bonus Scatters and four with four; five or six never landed. Two of them arrived on consecutive rounds, 7777 and 7778.

Is Big Splash worth more than ordinary Cash Spins in Big Catch Even Bigger Bass?
Lab answer

No, going by this test. The 36 Big Splash bonuses averaged 45.63x the stake with the trigger spin counted, median 43.8x, and the 10 plain Cash Spins averaged 46.06x, median 40.8x. Big Splash held both ends of the range, 94x in round 989 and 0.4x in round 9059.

What does Pick a Fish give at the start of Big Splash Cash Spins?
Lab answer

The fish picked reveal upgrades for that one bonus, and the journal holds 93 picks across 36 Big Splash bonuses, each sequence closed by a COLLECT pick. Extra spins turned up 8 times and Two Way Pays 7 times; Next Level came up 3 times and started the meter at x2 each time, and only round 4133 went on to x3.

Can a base-game spin outpay the Cash Spins bonus here?
Lab answer

Yes. A single ordinary spin paid 72x in round 9306 and 60x in rounds 2394, 2600 and 7677, against a median natural bonus of 43.5x. The best round overall was still a bonus, Big Splash Cash Spins worth 94x in round 989, far below the x10,000 maximum in the rules.
