About Boat Bonanza Colossal Catch
Fishing-themed slots are popular, and most leading game studios have released one or several versions of them.
Slot developer Play’n GO’s Boat Bonanza is one of them, and since that game did the trick and entertained players worldwide, PnG decided it was worthy of a sequel, so here we have Boat Bonanza Colossal Catch.
At first glance, we had to double-check, so we hadn’t fired up the original version, as the sequel is more or less a copy in terms of graphics.
So, what’s new in this version? First, the volatility level has been decreased from high to medium, and the max win lowered from 5,000x to 3,000x the bet to appeal to an ever broader audience of casual players.
Some features have remained the same while a new collection meter has been introduced to this new version in the Free Spins. A familiar feature seen in, for example, Big Bass Amazon Xtreme.
Boat Bonanza Colossal Catch is available in 5 payout versions, and in this review, we will show which these are, what the difference between them is, and where to play on the best-paying version.

Boat Bonanza Colossal Catch RTP
The available RTP configurations of Boat Bonanza Colossal Catch average an 84.20%, 87.20%, 91.20%, 94.20%, or 96.20% payout.
To show you what the effect of a higher or lower Return to Player really is, we have done some calculations.
Based on a starting balance of €/£/$/100 and a stake of €/£/$/1 per spin, we can determine per RTP configuration how many spins it will theoretically take (excluding variance) before you run out of funds.
How many spins does it take before your balance goes below €/£/$/1?
RTP | Number of spins |
96.20% | 2,605 spins |
94.20% | 1,706 spins |
91.20% | 1,125 spins |
87.20% | 773 spins |
84.20% | 626 spins |
Now, it is a good thing to realize that these calculations are based on theoretical losses per spin. In practice, due to the slot’s medium variance, results will differ significantly as you will have many losing and some winning spins. But taking the variance out of the equation, you can see enormous differences between the RTP settings.

Now that you are aware of the different RTP versions and the possible implications of playing on the various options, you may want to choose the best-paying version of Boat Bonanza Colossal Catch.
The issue here is that online casinos can freely choose whichever RTP version of the game they like, and many of them choose one of the lower-paying options to increase their win margins and profits.
However, we have done the research for you and found some top-rated online casinos that offer players the 96.20% RTP version of Boat Bonanza Colossal Catch, and you will find them listed here on this page.
Gameplay and features

Check these highest max win slots if you seek much bigger max wins.
CasinoWizard’s verdict: 2 out of 5 stars
Boat Bonanza Colossal Catch is not a bad slot. It’s just that it doesn’t really add that much new compared to the original version.
The collecting bar in the Free Spins adds a fun element, but this has already been seen and used many times in other fish-themed slots.
Play’n GO is a premium slot developer, but since they constantly release so many new slots, they occasionally might take some shortcuts to manage their hectic launch schedule.
