About this game

Dive into Jellyfish Arena Survivor io, a fast-paced jellyfish game where every swim can turn you from a tiny ocean drifter into the ruler of the arena. Eat, grow, dodge and survive against up to 100 aggressive rivals in a colorful underwater world.

SWIM, EAT, GROW AND SURVIVE

Start small and guide your jellyfish through a dangerous ocean arena. Collect glowing food to grow longer and stronger, outmaneuver smaller rivals and stay clear of every giant jellyfish hunting nearby. Smooth snake style movement makes this io game easy to learn, while faster opponents and crowded waters make survival difficult to master.

FACE A 100-RIVAL ARENA

Every survival run is packed with AI-controlled opponents that chase food, attack vulnerable jellyfish and compete for first place. This delivers the excitement of a multiplayer-style battle game while remaining a solo arena experience. Watch the rival count shift as opponents enter and fall, and keep growing until you dominate the ocean.

CLIMB THE LIVE LEADERBOARD

Track the ten largest rivals on the leaderboard as your jellyfish grows. Hunt competitors, protect your size and push toward the number-one position. Reach the top of this underwater battle arena and claim the crown as the biggest jellyfish in the sea.

EXPLORE THE OCEAN ARENA

Use the minimap to navigate the underwater world, locate danger and track the leading rival. Every arcade run creates new chases, escapes and close calls. One smart turn can save you from a larger enemy, while one mistake can end your survival run.

UNLOCK JELLYFISH SKINS

Earn pearls as you play and collect colorful jellyfish skins. Choose your favorite look before entering the arena, complete more runs and build a collection that stands out across the ocean.
