What they share
Fish symbols carry cash values. In ordinary spins those values do nothing special. In free spins a fisherman wild collects every value in view, and that is where both games pay.
Where they part
Big Bass adds a progression: each fourth fisherman extends the round and multiplies fish values, up to 10x. Fishin' Frenzy has no ladder but a ceiling more than twice as high. Both have sequels with different figures; these reviews cover the originals.
