Play Sonic Advance 3 (Cezar) (J) Online

Sonic Advance 3 (Cezar) (J) is a fast-paced platformer where you team up with another character—either in co-op or solo—to fix a world Eggman shattered. The first few levels throw you right into that classic Sonic speed, but with a twist: your second character tags along, adding little assists like extra jumps or attacks.

I remember playing as Sonic with Tails following, and the way their abilities stacked made some sections feel smoother than in past games. But the camera doesn’t always keep up when you’re blasting through loops, which can lead to blind jumps. The partner system keeps things fresh, though—switching pairs changes how you approach levels.

It’s still a GBA Sonic game at heart, so expect some slippery physics and moments where you’ll swear the game just hates you. But the chaos emerald hunt and co-op modes give it more replay value than most. The music’s got that upbeat Sonic charm too.
