Tips:

As the rounds progress, you will need to catch fish at depths deeper than your starter line can go; use scales cut off fish to CRAFT longer and stronger lines!

You can upgrade Health, Lung Capacity, Reel Speed, Grip, and more to get better and make the game easier to win. Learn the crafting formulas and collect the scales by battling fish.

You can DOUBLE the money you earn by finding PEARLS hidden in CLAMS at the seafloor, but you need to buy a DIVING BELL to look for them.

You don't have to WIN every round to advance, but the points add up, and you will NOT RECEIVE ANY POINTS if you fail to catch a fish before time is up, OR if you fail to get at least 3rd place in a round.
