Big Tuna Bonanza RTP (97.20%), house edge & 500-spin session math
Big Tuna Bonanza by BGaming returns a published 97.20% RTP (2.80% house edge) across a 5×3 / 5×4 HTML5 video grid layout and calls for a 150x–200x bankroll buffer in A$ at Here2Win Casino (here2win.com.au).
This BGaming release stands at +0.72 percentage points against the 96.48% studio average across 170 RTP-published titles (rank #19 of 170).

What provider is behind Big Tuna Bonanza?
BGaming is the studio named on the Big Tuna Bonanza card. Pokies Baron groups the rest of that studio on the provider page.

How a session behaves
A session at Pokies Baron is described as a limit and a stop, not as a story. Big Tuna Bonanza either fits that or it does not.
Big Tuna Bonanza has no memory of last night. Stop on a clock. A published RTP, when the card has one, is a long sample, not one arvo.
A different studio, Pragmatic Play, has Big Bass Boxing Bonus Round under the Fish tag.
Who it suits
A medium-volatility pokie sits in the middle of the pack for pace. Big Tuna Bonanza is an ordinary session game at Here2Win Casino, not a system.
