Big Bass Boxing Bonus Round Slot Review

Big Bass Boxing Bonus Round is a New Slot from Reel Kingdom that takes the ordinary 'Big Bass' bonus FS round to a new level, thanks to an extra counter trail. As a result, both meters allow for generating up to 60 additional Free Spins. Moreover, there are win multipliers of up to x10 present as well. Money symbols available during Free Spins come up with instant prizes of up to x5,000 the stake. All in all, it's another alluring follow-up to the world-renowned slot series, including titles like Big Bass Bonanza Megaways Demo, that is undoubtedly worth your attention. Let's examine its rules in more detail.

Big Bass Boxing Bonus Round - Base Game

Big Bass Boxing Bonus Round Play Free Demo

Sometimes, players want to get acquainted with new games that have recently been launched into the market before risking money. Fortunately, it's possible due to the demo mode, which utilizes fake currency and is introduced in most contemporary slot machines. Besides mock bets, there are no distinctions between a free slot and a real-money slot. That makes the demo mode helpful for novice and seasoned players, allowing them to assess a particular game's pros and generosity on their own. You can try this game out right on this page without needing to go anywhere, just scrolling up to the 'Demo' button. If you're comfortable with this title's gameplay, feel free to proceed to the trustable real money casino site accessible via the link above the demo button.

Big Bass Boxing Bonus Round Bonus Features

It is a High-Volatility Slot that takes players onto a 5x3-shaped playfield equipped with 10 fixed lines. Any winning combination must include at least two matching payout symbols lined up on adjacent columns starting from the far left one.

Scatter

This special symbol can appear on the screen only during the primary mode. It triggers the bonus FS game whenever three or more scatters are in view. The number of starting Free Spins depends on the current Scatters’ quantity:

Scatters

Starting FS

3

15

4

20

5

25

Additional Chance Feature

When only two Scatters spot the play grid, one of two listed features can trigger, giving an additional chance of Free Spins activation:

  • If both Scatters are higher than the third row, respins may start, rotating only those reels with no special symbols. Respins are ongoing until any Scatter gets to the bottommost row. Therefore, the maximum number of respins available within this feature's action is 2.
  • Additionally, a hook animation may pull in the missing Scatter onto the screen.

The bonus FS game starts once at least one additional Scatter hits the playfield, thanks to any of these features.

Free Spins (FS)

The bonus FS game differs from the base one, employing profitable Cash-collecting mechanics that utilize Wilds and Money symbols.

Money symbols

Fish symbols are special Money symbols that carry cash prizes, which can be collected only during Free Spins. Their possible values fluctuate in the wide range from x2 to x5,000. These cash prizes can only be collected with the help of Wild symbols.

Wild Symbols

The bonus mode uses two types of Wilds: red and blue. Both are collected by separate meters that contribute extra Free Spins (+10 FS) and win multipliers (x2, x3, x10) for every fourth Wild collected. Therefore, the maximum number of available extra Free Spins reaches 60.

Additional Chance Features

Additionally, three random features can increase your possible income via cash collecting:

  • Fish symbols can suddenly appear on the grid when there is a Wild symbol but no Money symbols on the screen.
  • Also, when the Wild is in view, but there are no Fish symbols, the ‘Knock Out’ animation can trigger, replacing all symbols on the screen except for the Wild with a random one, which gives a chance for Fish symbols to appear during the current round.
  • If there are Money symbols in view but no Wilds, the 'Hook' animation can pull a Wild onto the screen.

Big Bass Boxing Bonus Round - Free Spins

Buy Free Spins

Luckily, this Bonus Buy Slot permits wagerers to buy bonus FS game activation for a price that is 100 times the bet. The number of Scatters that kick off Free Spins will be random.

Buy Super Free Spins

Also, players can purchase the Super FS round activation. This time, its cost is x300 by the stake. The only distinction is that each 3rd Wild collected brings extra FS and a higher win multiplier. The number of Free Spins will be random (15-25), depending on how many Scatters landed.

Ante Bet

Additionally, one can accelerate the bonus FS game triggering by enabling this option. Its cost is 50% of the current stake per round.

Our Experience Playing Big Bass Boxing Bonus Round

Additionally, we tested this title through a 300-spin gaming session. The initial balance amounted to €200, while the stake per round was €1. Be aware that it was the Best RTP Slot (96.5%).

The first hundred spins triggered no FS rounds. Nonetheless, we recorded 12 regular wins, 7 of which were lower than €1. The smallest prize was € 0.20, while the largest one was only €5. So, when 100 spins were completed, our balance had decreased to €116.70.

The following hundred spins finally triggered Free Spins. Moreover, as many as two bonus FS games resulted in a total of €157.20. The ordinary cash prizes numbered 12, including five wins that were lower than the established stake. Their values varied from €0.2 to €5.5. Once the 200th spin was left behind, our balance was €192.

The ultimate 100 spins activated two other bonus FS games. Unfortunately, these were less generous than the previous ones, generating 'only' €69.6. The number of regular prizes, this time, was 11. Only four rewards were smaller than the bet. Moreover, the largest cash prize reached €11. It was a single reward that exceeded the € 10 threshold. When this experiment was eventually completed, our final balance was €195.7. Hence, we lost precisely €4.3.

Our Verdict

As one can see, wins were very infrequent (1 in 8.6 spins). Despite the prevalence of those larger than the bet amount, the number of small prizes was significant (16 vs. 19). All that makes it evidence that the primary mode here isn't constructed for generating jackpots. Luckily, the immersive bonus mode provides up to 60 extra Free Spins and multipliers of up to x10. The bonus FS game hit frequency is high (1 in 75 spins). Partially, this is because players only require 3 Scatters to initiate the feature. Additionally, whenever only two special symbols appear on the screen, re-spins start, contributing further odds to trigger the mini-game. Officially, it is the double-better bonus FS game that has ever been presented within the Big Bass series, considering it features two Wild counters, each providing extra FS and multipliers.

Concluding this Slot Review, it's a spectacular gambling title from a reputable iGaming developer with an incredible bonus game, which became the next step in the evolution of Free Spins, the 'Big Bass' series is famous for. So, if you're a big fan of Reel Kingdom's 'Big Bass' series, it's a great release you shouldn't miss out on. We also recommend trying the Big Bass Bonanza Demo to get back to the roots of this iconic series. In the meantime, this game is high-volatility, which means that gamblers on a budget may be disappointed by their losses while playing it. On the other flip, it's a nice fit for high rollers because of the quite convenient betting range (€0.1-€250) and decent maximum cash prize (x5,000).
