Dr. Mario World is a discontinued puzzle game in the
Dr. Mario series for
iOS,
iPadOS, and
Android devices. It was a free-to-download game with in-app purchases that was co-developed by
Nintendo,
LINE, and
NHN Entertainment, and it was available initially in 59 countries/regions, including Japan and the United States. The game supported multiple languages, including Japanese and English.
Dr. Mario World is the second game of the
Super Mario franchise for mobile devices, following
Super Mario Run, though it is the first free-to-play mobile game featuring microtransactions and gacha mechanics in the
Super Mario franchise. Like
Super Mario Run, the game required a constant internet connection to play. It takes advantage of the touchscreen controls of the smartphone, where players dragged
capsules with the touchscreen to eliminate
viruses, though the core gameplay is slightly tweaked in comparison to prior
Dr. Mario titles in that players solved puzzles with a limited number of capsules rather than infinite capsules against a time limit.
