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 NZ$ at Here2Win Casino (here2win.co.nz).
This BGaming release stands at +0.72 percentage points against the 96.48% studio average across 170 RTP-published titles (rank #19 of 170).
