Sonic the Hedgehog is a Sega Genesis action-platform game starring Sega’s blue speedster in his original 16-bit adventure. The game is built around fast side-scrolling stages, loop-the-loop terrain, tunnels, and Sonic’s spin attack.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• High-speed platforming emphasizes momentum, quick reactions, ring collection, and hazard-filled stage routes.
• Sonic uses the spin attack to blast through enemies and keep speed through curved level designs.
• Stages include molten lava, waterfalls, green mountain areas, city lights, and a 360-degree rotating maze.
• The adventure follows Sonic as he fights to free his friends from evil.

This release introduced the Sonic series on Sega Genesis and established the speed-focused platforming style that shaped later entries like Sonic the Hedgehog 2.
