Catching fish will award you with points which are added to the overall fishing license progress from the fishery you are on.
After earning a certain amount of points for one of your fishing licenses it will be automatically levelled up.
Every second level you will gain the ability to draw a random licence bonus.
License bonuses are useful passive bonuses that work all the time. By drawing a correct set of rod bonuses, you will be able to compete at a higher level.
Bonuses only work when catching fish that they are designated to. Every bonus works for one fish only and you may have only one fish type buff drawn on your Fishing License.
Bonuses are divided into rarity groups, rarer bonuses are much more powerful but may require several wheel spins.
Passive bonuses will boost the weight, chance and shorten the time for its designated fish.
The first draw on every level is always free. After that, you may try to draw a better bonus but you will have to pay 2 pearls for a single draw or 90 for a larger set.
