Big Bass Boxing Bonus Round review
Big Bass Boxing Bonus Round, released by Pragmatic Play in 2025, moves the fishing series into a boxing ring. The base game pays for matching gloves, shoes and skipping ropes, but the real action is in the free spins. There, a blue wild and a red wild each fill their own meter, and every fourth wild lifts the multiplier and adds spins. Money symbols can reach 5,000x, according to the studio.
The base game and the scatters
Up to five matching symbols, such as boxing gloves, shoes and skipping ropes, award a prize in the base game. Three, four or five scatters trigger the bonus game with 15, 20 or 25 free spins. The studio does not describe any other base-game feature in the text we hold, so the free spins carry most of the design.
Two meters in the free spins
Money symbols with values of up to 5,000x can be won during the feature by landing either a blue or a red wild. Each colour has its own meter, and every wild that lands moves its meter forward.
After every fourth wild a meter levels up. That awards 10 more free spins and raises the win multiplier. The studio states that prizes are multiplied by 2x on the first level up, 3x on the second and 10x on the fourth and final level. The third step is not stated in the text we hold, so it should be checked in the game.
Blue and red wilds
Either wild lets a landed money symbol be won, and each progresses its own meter. Because there are two meters, two separate sets of level-ups can run during the same round, each extending the spins and the multiplier.
Cost of a session
The only RTP on record is 96.5%, a house edge of 3.5%. Over a long run that is about $35 lost per $1,000 wagered. A hundred spins cost $0.70 on average at $0.20, $3.50 at $1 and $17.50 at $5.
Volatility and max win are not published in our catalogue. The 5,000x figure applies to a single money symbol in the feature, so it is not an overall cap. A free demo is available from the studio.
Other releases at 96.5%
Many 2025 releases in the catalogue list the same 96.5%. Among those with a max win, 5 Lions Megaways 2 reaches 8,000x, while 5 Lions Reborn and Alien Invaders list 5,000x. 777 Rush, Big Bass Halloween 3 and Bigger Barn House Bonanza do not have a max win in our data.
Pros
- Two meters can level up independently in the free spins
- Every level-up adds 10 free spins and a higher multiplier
- Starts at 15 free spins for three scatters
- Free official demo available
Cons
- No volatility or overall max win in the catalogue
- The multiplier for the third level is not stated
- Most of the value sits in the free spins
Verdict
Big Bass Boxing Bonus Round is a feature-heavy variation on a fishing theme, with scatters worth 15 to 25 free spins and two wild meters that raise the multiplier up to 10x. The 96.5% RTP gives a 3.5% house edge, and with volatility unpublished the free demo is a better guide to the pace than any label. Set a budget first and treat the money symbols as an upside, not a plan.
