Dr. Mario World is an interesting mobile game where you have to use your puzzle solving skills to get rid of dangerous viruses. That being said, in order to kill these viruses you are required to match capsules containing them and make them vanish. The matching system works by asking for three objects of the same color layed out on the vertical or horizonal lines in order to remove them.
Moreover, you're not alone is this important fight. Doctor Mario and his friends can use leftover half-capsules to continue the fight against these pesky viruses. Each mission contains a limit of capsules that can be used to get rid of that specific virus configuration. Another cool aspect of Dr. Mario World is the ability to have a blast while playing against real players thanks to its Versus mode.
Each stage of this game takes you through various worlds where you will find new doctors and challenges.
