Play AntiXonix Online
You carve out territory with quick mouse strokes while dodging manic bouncing blobs—mess up and your safe zone shrinks fast, leaving you scrambling. That satisfying *blip* when you trap an enemy never gets old.

Game Overview
Ever fire up an old MS-DOS game and immediately get sucked in for hours? AntiXonix is one of those—it takes the basic Xonix idea (you know, drawing lines to claim space while avoiding bouncing enemies) and turns it into something way more frantic. The play area shrinks faster, the enemies zigzag unpredictably, and before long you're white-knuckling the keyboard as some neon pixel blob barely misses your tail.
What I love is how it looks deceptively simple at first—just a square playfield and some blocky sprites—but by level 3, you're sweating. The sound effects are pure DOS-era charm too: that crunchy "blip" when you trap an enemy, the ominous drone when your remaining space turns red. It’s the kind of game where you lose and immediately hit "play again" because this time you’ll nail that perfect diagonal cut.
If you miss the days of unforgiving arcade logic and no hand-holding, this one’s a time capsule worth digging up. Just don’t blame me when you realize it’s 2 AM and you’re still muttering "one more round."
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
