Dr. Mario - Classic NES Series is a Nintendo Game Boy Advance puzzle game that brings the NES-style virus-clearing formula to handheld play. The game centers on Dr. Mario tossing multi-colored vitamins into Mushroom Kingdom Hospital to eliminate matching viruses.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Educational/puzzle gameplay built around matching capsule colors with viruses inside a bottle-shaped playfield.
• Adjustable level and speed settings shape each round, with higher virus counts increasing the challenge.
• Two-player competition is supported for head-to-head virus-clearing matches.
• Multiplayer requires one Game Pak plus either a Game Boy Advance Game Link Cable or two Game Boy Advance Wireless Adapters.

The Classic NES Series release keeps Dr. Mario focused on quick, score-driven puzzle rounds rather than adding adventure stages or side modes.
