Mario trading his overalls for a lab coat was Nintendo's follow-up to the Tetris craze, and the Game Boy version launched in 1990 alongside the NES release. The goal is to clear a bottle of viruses by dropping two-part vitamin capsules onto them; lining up four of the same type, horizontally or vertically, wipes out the matched segments and any viruses caught in the line.
On the monochrome screen, the three virus colors are told apart by distinct patterns and shapes, which works better than you might expect. The handheld version keeps the virus level and speed settings from the NES game, plus the two music tracks, Fever and Chill. A link cable enables two-player versus matches, where clearing several lines at once sends garbage pieces over to your opponent's bottle. The design is simple enough to learn in a minute, but higher virus levels fill the bottle almost to the top and demand real planning.
Tips for Dr. Mario
Leave one column open as a drop shaft so a stray capsule never blocks the bottle's neck.
Clearing two or more matches from one capsule drop is what sends junk to a link-cable opponent.
Single-color capsule halves left behind after a clear fall freely, so set up cascades on purpose.
