Tried to switch it up, didn’t quite land

I liked the switch to tuna instead of bass, but the gameplay doesn’t really innovate. Prize lines are a nice touch, but features are basic. It’s a fine time-waster, but I wouldn’t go out of my way for this one.

Good catch, solid run

Big Tuna Bonanza plays it safe—familiar catch-and-collect style, but the RTP held up. Bonus round paid 328 on a 5 bet, so not bad at all. The wilds and multipliers helped push it up. Doesn’t reinvent anything, but definitely worth a few spins.
