Bubblebound

Your fish swims and fights automatically. Spend shells on attack, health or speed; use Reef burst for a helping hand. Regular reefs have three encounters, an elite and a guardian; chapter finales are single-guardian duels. Revisit cleared reefs to farm, or auto-advance.

Defeat causes a short rest, then farming on an earlier reef - no lost loot. Offline expeditions estimate shells, XP and equipment from your crew’s performance on a cleared reef, capped at 24 hours. Farming contracts advance; new reefs do not unlock. Unsafe expeditions rest without rewards. Progress is saved in this browser. Clearing browser data removes that save. Explore 12 chapters across Calm, Surge, Tempest and Mythic: 240 regular reefs plus four separate grand finales. Each chapter ends in a guardian duel. Each difficulty has three chapters followed by Luma, Morrow, Nacre or Orin. Earlier difficulties stay available for farming.

Build a cute fish crew, collect equipment and explore 12 chapters with 240 regular reefs and four grand finales. Battles run automatically while you choose gear, skills and your next expedition.
