Oib.io

Command a squirming horde of oibs and devour rival swarms in this fast-paced multiplayer arena where only the biggest blob survives.

You ever play a game that's basically a war of amoebas? Oib.io drops you into a big open map with a handful of squishy little oibs under your command. Left click to pick one, drag a box to grab a bunch, or smash spacebar to select every oib you've spawned. Right click moves them where you want, and here's where it gets interesting: hit '1' to pump out fresh oibs, and '2' to merge selected ones into a single beefy blob. More oibs means more mass, but a merged giant hits way harder and can bulldoze through smaller swarms. The real fun is the tension between spreading out to farm and clumping up to fight. I remember one match where I was happily munching on little dots, my oibs spread all over like spilled rice. Then some red swarm three times my size rolls in from the left side. I panicked, boxed all my oibs, mashed '2', and watched them squish together into one chunky boi. The red swarm hesitated for a split second—that was my opening. I right-clicked straight into them and just steamrolled through, absorbing every last one. Felt incredible. Camera control with WASD or arrow keys takes a minute to get used to, but it's essential for scouting danger before it's too late. There's no tutorial, no hand-holding—you learn by dying a few times and realizing you should have kept a retreat squad. Oib.io isn't fancy, but it scratches that primal 'grow and conquer' itch better than most .io games out there.

Use spacebar to select all oibs instantly when a fight breaks out. Always keep 2-3 oibs off in a corner as an escape reserve. Merge with '2' just before engaging—a fused blob hits like a truck. Ctrl+click lets you peel off damaged oibs without breaking your whole swarm. Move the camera with WASD to scout enemy positions before committing. Spam '1' early to build numbers, but don't forget to merge for focused power.
