SeaDragons.io

SeaDragons.io casts you as a deep-sea serpent fighting for survival in a snake-style ocean arena. Devour fish and plankton orbs to grow longer and heavier, then use your size to trap smaller dragons.

Complete quests to earn cards featuring different species and level up the dragons you own. Sprint by clicking or holding the left mouse button, but remember sprinting drains mass — use bursts sparingly.

Steer with the mouse and never strike another dragon's body with your head. One collision ends your run, so length is power only when paired with careful routing.
