The classic falling‑block puzzle game that turned Mario into a doctor makes its portable debut in Dr. Mario for the Game Boy. Released alongside the NES version in 1990, this handheld edition delivers the same addictive, color‑matching gameplay — now perfectly tuned for on‑the‑go play. Inside a laboratory overrun by three types of mischievous viruses, Dr. Mario tosses in two‑colored capsules. Your job is to rotate and position each pill to line up matching colors and eliminate every virus on the screen. With multiple speed settings, dozens of levels, and endlessly replayable mechanics, Dr. Mario remains one of the most iconic puzzle games of the early handheld era.
