I don't mind Big Money Bass, it's pretty low-volatility and you get into the fishing game fairly frequently. The entry into the bonus is quite unique, and if you land a 4 of a kind fish win you go straight in.
The bonus itself isn't particularly well executed in my opinion, with things happening at random and a lot of faffing around trying and failing to hook multipliers up to the boat. The fish then goes on a rampage and eats a load of other fish which frees up more positions so you can land more fish, but you very rarely seem to do this so it gets quite frustrating.
I think there should be highlighted positions in the window and if a fish lands there the guy in the boat will try and hook it up, rather than it just happening out of nowhere. I also think it would have been better to have some sort of dial, a bit like on Reactoonz 2, that fills up by one position each time a fish comes in. If you fill it up you are shown a wheel like on Ave Caesar DW which spins and awards one of the enhancements. Or when you run out of lives the dial spins for a chance of triggering the enhancement wheel and continuing the bonus, and the fuller the dial is the better the chance you have.
As it is you've just got a fishing game with loads of extra stuff that can happen that the player cannot see unless they read the help pages. Stuff just arbitrarily occurs for no reason and it's hard to see where the big money is because of this. Shame really because the bonus mechanic it a pretty good idea.
Bigger Money Bass just added some coins to the reels which tease for trivial amounts and don't look like they can pay anything over 10x. A few extra things in the bonus that don't add a lot to the game, and that slow spin on the last three mini-reels when you're getting booted out is probably one of the most annoying things I've ever seen in a slot game. You don't tease out losing scenarios FFS; that's just daft.
