This is the latest mobile game to come from Nintendo and up until now has remained exclusively available since launch to devices running on iOS.
According to the Play Store listing, you should expect to have to work your way through 6 worlds and 24 courses before reaching Bowser’s Castle.
In terms of the download, this is a free to download game, although you can and should expect to pay to unlock the full game’s functionality.
For those just looking to test the game out for free first, in addition to being able to test-run World Tour, Road Rally, and Kingdom Builder, you will also be able to play through the first world.
In Mario talk, that is stage 1-1 through to 1-4.
