Nintendo has announced Dr. Mario World for smartphones.

The new spinoff game is coming to iOS and Android devices sometime in early summer of this year in roughly 60 countries – including Japan and the United States.

The game is developed in collaboration with LINE Corporation, and will naturally be free-to-play with in-game microtransactions.

Here’s a rundown on the game:

Utilizing both companies’ strengths, Nintendo and LINE will co-develop and jointly operate a new action puzzle game featuring Dr. Mario titled Dr. Mario World to be released by Nintendo. Dr. Mario World is targeting an early summer 2019 global release, including in Japan and the United States.

Together with Nintendo and LINE, NHN Entertainment, which has released and operated various online and mobile games, will take part in the development and operation of Dr. Mario World.
