How it plays

How does Sonic & Knuckles play?

The game is a side-scrolling platformer viewed from the side. Players move through multi-act zones, collect Rings, defeat enemies, activate checkpoints, and reach the goal before confronting zone bosses.

Sonic uses speed, jumping, rolling, and the Spin Dash. Knuckles follows different routes by gliding across gaps and climbing certain walls. Special Stages award Chaos Emeralds, while bonus areas provide additional rewards. The standalone cartridge includes Sonic and Knuckles campaigns; lock-on play can add connected Sonic 3 content and additional playable characters.

Plan your run

What is the best way to play Sonic & Knuckles?

Explore before rushing forward: branching paths often hide Rings, shields, extra lives, and entrances to Special Stages.

  • Use the Spin Dash to build speed safely and attack ground enemies.
  • As Knuckles, check climbable walls and glide across gaps for alternate routes.
  • Preserve Rings before boss encounters, and use checkpoints to reduce the cost of mistakes.
  • Learn boss patterns rather than attacking recklessly; most encounters have clear openings.
