Start with two tanks
Two normal species tanks are active at a time. Finished tanks retire and the next species slides in.
Fish tumble into the reef in mixed glass bubbles. Tap any fish, route it to the correct species tank, and clear the whole board.
AQUASORT V0.3.2 adds Special Reefs to the sorting loop. Mixed bubbles still fall into the main tank and two species tanks stay active, but certain reefs now hide luminous Pearlfin among the regular fish.
Complete the Pearlfin set to earn an Unlock Pearl. The pearl can open a faded wildcard Bonus Tank — AquaSort’s strategic escape hatch when the five-slot holding current gets tight.
Lifetime score is stored in AquaSort. BPNet separately tracks each player’s verified best run for Arcade Score.
Finish reefs while signed in to permanently add encountered species to your BPNet-linked AquaSort profile.
Two normal species tanks are active at a time. Finished tanks retire and the next species slides in.
Open species swim directly home. Locked species wait in the five-slot Holding Current.
Special Reefs include three luminous Pearlfin. Sort all three into their special current to earn an Unlock Pearl.
The faded Bonus Tank begins locked. Once your pearl is ready, tap the tank and watch it come alive.
The unlocked Bonus Tank adopts the first locked species you send to it. You can also tap a fish already in Holding to choose that species and immediately pull matching held fish across.
The Bonus Tank is optional, just like an extra bottle in PrismPour. Save it until Holding gets dangerous, or use it early to chase a cleaner score.
