About Gloop Arena: Offline Slime io
Start as a tiny slime. Finish as the thing everything else runs away from.
Gloop Arena is a fast, friendly .io-style arena game about one simple pleasure:
eating things slightly smaller than you, over and over, until nothing on the
map is safe. Slide your slime around eleven hand-built arenas, swallow food,
cars, trees, whole buildings, then start swallowing your rivals.
And all of it runs offline. No internet, no account, no sign-up, nothing to
connect. There is no advertising and no in-app purchases in this release.
PLAYS FULLY OFFLINE
Every mode, every arena and every unlock works with no connection at all. Take it on a plane, on the metro, into a dead zone. Your rivals are AI, so the arena is never empty and never needs a server.
FOUR WAYS TO PLAY
• Solo: five rivals, one arena, one winner. The classic .io run.
• Teams: Blue against Red. You have three lives; make them count.
• Time Attack: no rivals, no mercy. Just you and the clock.
• Survival: endless escalating waves. How long can you last?
THE APEX HUNTS YOU
Survive long enough and an Apex arrives: a boss slime that stalks you,
telegraphs a red charge beam, then lunges. You cannot simply outgrow it. Eat golden food to charge your Slayer power, wait for the glow, then ram it head-on for a huge bounty. Beat it and a tougher one returns with a new color, a new face, a crown, a katana, each demanding one more golden than the last.
ELEVEN ARENAS
Rampage through a living City with real traffic and buildings that rebuild
themselves, a wild Jungle, a dusty Western town, a sunny Meadow, a working
Farm, a Medieval keep, a Japanese garden, a frozen Snowfield, a Pirate Cove, a Candy land, and Deep Space.
MAKE YOUR SLIME YOURS
25 colors, 15 faces, 22 themed outfits and 7 particle trails. Outfits are tied
to their arena: unlock the Farm and the Farmer and Scarecrow go on sale; open Deep Space and the Astronaut is waiting. Mix any color with any face, outfit and trail.
ALWAYS SOMETHING TO CHASE
30 achievements plus an endless rank ladder, reward chests, a daily prize
wheel, a daily challenge, a login streak, and player levels with level-up
gifts. Every round pays coins, and every reward is earned offline.
FEELS GOOD ON A PHONE
One thumb to steer, one to aim your Dash. Drag away from the Dash button to point the lunge anywhere, release to fire. Chunky, juicy, readable, built for
short sessions and one-more-round evenings.
EAT, GROW, WIN
A small slime eats food. A bigger slime eats cars. A big enough slime eats the other slimes. That is the whole loop, it runs offline, and it never stops
being satisfying.
Multi-Languages supported
Full support for English, Arabic, Portuguese, German, Turkish and Spanish languages, switchable any time from the settings menu.
