The game was first teased in February and a full trailer was released in June.
"Dr. Mario World" introduces Mario and his friends as doctors with special skills. Players can purchase optional items for the game from the app.
In the game, players must deal with viruses by combining capsules to form a set. Each stage has a limited number of movements, in a formulation reminiscent of the very popular mobile game "Candy Crush Saga". Things warm up to more advanced levels when players face obstacles and new cards.
Although the game is free, Nintendo offers a real revenue opportunity with its new game: the integrated purchases for "Dr. Mario World" range from 1.99 USD to 69.99 USD.
Nintendo is increasingly interested in mobile games, having initially preferred to launch the games directly on its own consoles. His success has varied: his greatest hits have been "Pokemon Go", "Super Mario Run" and "Fire Emblem Heroes". "Super Mario Run" is loosely adapted from the original console.
But the popularity of "Super Mario Run" has collapsed. He only reported $ 90,000 last month.
The Switch Lite is designed to be exclusively portable. This means that he can not connect to the TV as the switch. It has built-in, non-removable controllers. It will cost $ 199.99 and will be released on September 20th.
