⚠️ 18+ | This content contains affiliate links. This website is not affiliated with Red Tiger, Evolution, or Pragmatic Play; all trademarks belong to their respective owners.
Updated: July 2026
The Red Tiger is Pragmatic Play's response to the success of the Big Bass Bonanza—and perhaps the most well-executed reimagining of the formula. Here, they solved the main problem of the entire Pragmatic Play series: The collector is active not only during free spins, but also in the base game.
Plus, it was released in 2025 Megaways - Megaways Slots Online Casino-The version with a ceiling of ×25,539 is higher than that of any game in the Big Bass series, including the 1000 version with its ×20,000 ceiling.

* Evaluation of independent platforms: Red Tiger does not publish its own verbal volatility rating; see below for details.
The values for RTP, win frequencies, and maximum payouts are taken from the internal Red Tiger database, which is integrated into their official game pages.
⚠️ I'd like to point out two areas right off the bat where these platforms are mistaken. Some websites state that Bass Boss Megaways was released in August 2022—that is the release date of the base game. You’ll also see «maximum win of 51,079»—this isn’t a multiplier; the actual figure is ×25,539.
Regarding volatility: The Red Tiger uses its own numerical index in the database (17.18 for the Bass Boss and 24.07 for Megaways). This is the company’s internal scale, comparable only to their own games, rather than a «out of five» rating. The independent sites we checked describe both games as highly volatile — but that is their assessment, not an official figure.
Three Differences from the Big Bass Mechanism
The formula is the same—coin symbols plus a collector—but it is implemented differently in three key areas.
First: The collector works in the base game as well. In Pragmatic Play’s game, the fisherman only collects money during free spins, which is why the base game in the Big Bass series is frankly empty. Here, Bass Boss casts his line at any moment.
Second: The collection is done in a single row. The hook is lowered into random sequence and takes all the fish from it. If you're lucky, the Bass Boss can move the line to another row — a second chance. In Pragmatic Play's game, the fisherman collects everything visible on the screen, in its entirety.
Third: The counter counts fish, not collectors. In Pragmatic, every 4th fisherman you collect triggers a retrigger. Here— every 8 fish caught.
Contest Spins — Bonus Round
| Skaters | Spins |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
Key feature: The hook stays in the water for the entire round, rather than appearing only from time to time.
Round Progress:
| Fish caught | Award |
|---|---|
| 8 | +10 spins, ×2 multiplier |
| 16 | +10 spins, ×3 multiplier |
| 24 | +10 spins, ×5 multiplier |
| 32 | +10 spins, ×10 multiplier |
Maximum Four retriggers — 40 extra spins, whereas Pragmatic Play has three. The multiplier ladder is longer: ×2 → ×3 → ×5 → ×10 versus ×2 → ×3 → ×10.
There's another mechanic Improved Bait — Float multipliers: ×2, ×3, ×5, ×10.
Bass Boss Megaways: What's the Deal with ×25,539?
A standalone game from 2025, not a mode within the base game.
Grid 6×7 with 117,649 ways plus a separate one horizontal drum Below the main reel—it has its own exclusive symbols. Cascades are active.
Here, the float rests on random drum (rather than a row, as in the base game) and collects all the fish on it, after which they can cast again following a cascade. Mechanics Ground Bait ensures that there is at least one fish on the reel.
On the horizontal drum:
- Green fish — ×15–30
- Orange fish — ×50–200
- Golden Catfish — ×500–2,000
- Fish School — turns an entire vertical drum into a fish
- Underwater mine — collects all the fish on the reels
- Instant Contest Spins — instant access to the bonus
The hit frequency of 28,96%—that’s nearly every third spin—is significantly higher than that of the base version (19,04%), and those games in the Big Bass series where this metric is even published: for version 1000, it is 13.19%, and for the soccer version, it is 12.98%.
⚠️ Contest Spins does not publish the full paytable for the Megaways version of Red Tiger—it only lists «a multiplier of up to ×10.» There is no way to verify the scatter figures provided by third-party sites, so we are not repeating them here.
About Purchasing a Bonus
To be honest: It was not possible to determine with certainty. The Red Tiger database contains contradictory information for both games—one field says «purchase not available,» while another says «purchase available.» Additionally, the feature is subject to jurisdictional restrictions: it is prohibited in the United Kingdom.
Check to see if the button is available directly in the game with your provider.
Thoughts on the Game
Bass Boss is a rare case where a clone turned out to be better designed than the original.
The catch in the base game changes everything. In the Big Bass series, the base is just a waiting game, but here it’s alive: the hook can drop at any moment. The hit frequency of 19.04%, compared to 13.19% for Big Bass Bonanza 1000 and 12.98% for the soccer version, confirms this feeling (Pragmatic Play does not publish this metric for the other games in the series).
A single-row draw with the option to shift is an interesting solution: the outcome isn't predetermined, adding an element of suspense.
What spoils the picture— RTP 95,70%. This is significantly lower than 96.71% for Big Bass Bonanza and 96.72% for Blast the Bass - Crank up the bass. And in some builds, the Red Tiger reduces the RTP to 92.06%, which is quite uncomfortable. Always check the value in the game rules.
The maximum bet of 50 € is the limit for high-stakes play.
The Megaways version is more exciting than the base game in every way: the maximum payout is five times higher, wins occur more frequently, and there are significantly more paylines. If you have to choose just one, go with this one.

What to compare it to

Frequently Asked Questions
How does the Bass Boss differ from the Big Bass Bonanza?
Three things. The collector works in the base game as well, not just during free spins. The hook collects fish from a single row (with a chance to shift to an adjacent row), not from the entire screen. A retrigger is awarded every 8 fish caught, not every 4th fisherman collected—and there are four such retriggers, not three.
What is the RTP in the Bass Boss?
95,70% in the top configuration, according to Red Tiger data. There are also configurations of 94,77% and 92,06%—the specific value depends on the casino and is specified in the game rules.
Is Bass Boss Megaways a separate game?
Yes, a standalone title released on April 24, 2025. 6×7 grid, 117,649 ways to win, a separate horizontal reel, maximum payout ×25,539.
What is the maximum payout?
×4,835 in the base game and ×25,539 in the Megaways version. The number «51,079» that appears is not a bet multiplier and should not be used for comparison.
Is there a bonus purchase?
There is no definitive answer: our own Red Tiger database contains conflicting information on this field, and the feature itself is subject to jurisdictional restrictions. Check with your operator to see if the button is available in the game.
Final Grade
Bass Boss — 7.5 / 10 · Bass Boss Megaways — 8.5 / 10
In terms of design, this is the best reworking of the Big Bass formula: the collection mechanic in the base game addresses the genre’s main criticism, and the win rate is noticeably higher. It’s dragged down by RTP: 95.70% compared to nearly 96.7% for competitors, and in some configurations, as low as 92.06%. The Megaways version is noticeably stronger than the base game in every respect.
Gamble responsibly. Gambling is a form of entertainment, not a way to make money. The outcome of each spin is determined by a random number generator, and no strategy can influence it. Only gamble with money you can afford to lose.
If the game is no longer fun, seek help. International services: BeGambleAware.org - Link, GamCare - Link, Anonymous Players (Russian) - . Most casinos offer self-limitation and self-exclusion tools—make use of them.
