About Sonic.io
Sonic.io is an action io game where your goal is to run away and dodge everything coming at you while collecting rings. Sonic.io throws you into a live arena against players worldwide. Press Play and start carving out space. It leans fully into casual, so if that's your thing, it delivers. It's tuned to load fast and play smoothly whether you've got five minutes or an hour.
If you want to do well, keep this in mind: Stay near the edges in your first few minutes — the center is where everyone fights. Bank your gains often if the mode lets you — dying with everything un-banked is the classic trap.
Sonic.io plays free in your browser on Glaze Games — one click and you're in, on any phone, tablet, or laptop, with no sign-up wall.
