Another Nintendo mobile game has been confirmed.

Nintendo announced today that Dr. Mario World is coming to mobile devices. The puzzle game will be available on Android and iOS and will be free to download with optional in-app purchases. It'll launch in early summer 2019, with availability in 60 countries and regions to start, including Japan and the United States.

Also confirmed is that Nintendo will co-develop Dr. Mario World with Line, the company behind the popular chat app. NHN Entertainment will also be involved in the project.

Nintendo is one of the biggest names in gaming, but the company only recently started dipping its toes into mobile. It's released titles like Miitomo, Super Mario Run, Fire Emblem Heroes, and Animal Crossing: Pocket Camp over the past couple of years, and now we know that Dr. Mario World is coming, too. We also know that Mario Kart Tour is coming to mobile, but Nintendo said today that Mario Kart Tour has been delayed to summer 2019 so that Nintendo can improve the app's quality and expand its content after launch.
