Gameplay
As with previous Dr. Mario games, the player's objective is to eliminate all of the viruses on the screen by connecting capsules of the same color to each of them, although instead of the capsules descending, the game's gravity is directed upwards with the viruses positioned towards the top of the screen. The player first drags a capsule from the bottom of the screen onto the field to use it, and can drag it again to move it or increase its "falling" speed, or tap it to rotate it horizontally or vertically. Viruses are eliminated if three (as opposed to four) or more of the same color are matched. The classic red, blue, and yellow viruses return, while new green, purple, and cyan viruses make their debut.

Depending on the level, various obstacles may appear on the field, including Empty Blocks and Brick Blocks. Different-colored shells and bombs can also appear among the viruses which, when matched with capsules of the same color, clear out viruses on the same row and eliminate surrounding viruses, respectively. Some viruses are encased in bubbles, which shield them from capsules once before they disappear; or trapped in cages, only being released after clearing a lock on the field.

Levels are grouped into worlds, beginning with five – a grass-themed world, a desert-themed world, a beach-themed world, a ghost-themed world, and a sky-themed world – with more to be added in the future.

In order to play a level, the player needs to have at least one heart. Hearts are gained automatically as time passes, although players can purchase hearts with diamonds. Diamonds can also be used to obtain items and to continue a level should a player fail an attempt (although only one continue is allowed per attempt). Diamonds can be purchased through the app with real money.

Unlike prior Dr. Mario games, players are limited to a certain amount of capsules per level.
