Play Sonic – Code Gray Online

Ever come across Sonic – Code Gray? It’s one of those weird, unfinished Genesis roms that somehow became legendary among Sonic die-hards. The first thing you’ll notice is how off everything feels—the colors are washed out, the physics are janky, and some enemies look like they were drawn in a hurry. But that’s the point. It’s like playing a leaked beta version someone forgot to delete.

You’ve still got the speed and platforming you’d expect, but levels cut off abruptly or loop in strange ways. There’s no real story, just this eerie, glitchy atmosphere that makes it feel like you’re breaking into Sega’s archives. It’s short, rough, and definitely not for everyone—but if you’ve ever wondered what Sonic might’ve looked like before the polish, this is as close as it gets.

Honestly, half the fun is trying to figure out if a weird jump is intentional or just the game being unfinished. A total curiosity, but a weirdly compelling one.
