Small jelly. Clever moves.

JellyBlob is a free multiplayer arena game you can play right in your browser. Pick a name and a color, then enter the pond. No download or account needed.

Collect and grow

Steer with your mouse, touch, or arrow/WASD keys. Eat loose droplets to grow. There is no maximum jelly size. Connected slime trails are dangerous; loose droplets are food.

Hop and boost

Tap Space or the mouse button to hop over danger. On touch, use the Hop button. Keep holding after you land to boost. Boosting spends size quickly and leaves chunky food blobs behind for other players.

Bump, block, bounce

Jelly bodies bounce off each other. Use your body to block a route or nudge a rival toward trouble. Bigger jellies hold their ground more easily. Hop to clear another body. Trails still burst grounded rivals; they do not bounce.

Use the river

The bright blue river flows through the arena. Move downstream for extra speed. Moving upstream slows you down. Use the current to escape or make a clever turn.

A lucky little boost

Rare power-ups last five seconds, one at a time. Snack magnet pulls in nearby loose droplets. Spring jelly gets your next hop ready sooner. Light feet makes boosting cost a little less size. Look for their floating icons and your countdown.

Keep the pond stylish

Unlock hats and expressions through achievements. Some take a long run or many collected droplets. Share your personal invite link to earn five friend rewards at 1, 3, 5, 10, and 25 confirmed friends. The 5- and 25-friend rewards are special trails. Hats, faces, trails, and the optional supporter color pulse can be equipped together. Cosmetics never change gameplay powers.

Take your collection with you

Play as a guest, or choose Save your collection to sign in with Google or Discord. Your achievements and outfit come with you on another device. Use the same sign-in option each time. No recovery key to remember.

A live, growing garden

The current arena has 32 player spots. Bots fill quiet periods and make room for human players. If the pond is full, the queue shows your position and joins you automatically when your spot opens. We plan to expand capacity as the community grows.
