As promised, Super Mario Run, Nintendo's first real smartphone game, launched on the App Store today, December 15. The side-scrolling, auto-runner platformer is available free of charge with a non-compulsory $9.99 upgrade to unlock the game's three modes completely.
If you don't see the GET button quite yet, force refresh the App Store app, then simply tap on the Notify button in the App Store description of the game. Enter your password or use Touch ID when prompted, and the game will begin downloading. If that doesn't work, iDB editor Jim Gresham suggests force-quitting the App Store app, rebooting the device, launching the App Store app, and then download the game.
The anticipated title is optimized for one-handed play: as Mario automatically runs from left to right, you just tap the screen to make him jump. The longer you touch the screen, the higher he jumps. As with other Mario games, you'll be avoiding various obstacles and collecting coins along the way whilst attempting to get our hero safely through the level in the fastest time possible.
