Play Sonic and Knuckles Online
Sonic blasts through loops while Knuckles smashes walls and glides—levels flip gravity on you, and plugging in Sonic 3 turns it into one huge, chaotic ride. That cartridge slot still feels like magic.
Sonic and Knuckles is the kind of game that makes you realize how much fun you can have with just a Genesis controller and some serious momentum. Yeah, Sonic's still the star, but Knuckles steals the show—gliding through levels like he owns the place and punching through walls like they're made of paper. The levels twist and flip in ways that still feel fresh, especially when you hit those wild gravity-defying loops.
But the real trick? That cartridge slot on top. Plug in Sonic 2 or Sonic 3, and suddenly you're playing a whole new game—Knuckles in Sonic 2 feels weirdly right, and Sonic 3 & Knuckles turns into this massive, ridiculous adventure. The music slaps, the speed never lets up, and those special stages? Still as frustratingly addictive as ever. If you've got a Genesis lying around, this one's a no-brainer.
