Introduction
Released in 1990, Vs. Dr. Mario brought Nintendo’s viral puzzle game to arcades through its flexible Nintendo Vs. System platform. With its catchy music, falling capsules, and germ-busting gameplay, Dr. Mario was already a home hit. The Vs. version amped up the competitive challenge, allowing head-to-head play and timed matches that tested both reflexes and strategy.

Development and History
- Developer: Nintendo R&D1
- Publisher: Nintendo
- Release Date: 1990
- Hardware: Nintendo Vs. System (Vs. UniSystem and Vs. DualSystem)
Vs. Dr. Mario was released after the original Dr. Mario made its debut on the NES and Game Boy. This arcade port took advantage of the Vs. System’s modular arcade design, allowing operators to easily swap game boards and encourage competitive multiplayer setups. It offered either single-player virus-clearing or two-player battles via linked screens.
It was among the later titles for the Vs. System, appearing just as Nintendo’s home dominance grew with the SNES looming.
