Simple arcade fun, making corners is satisfying and bumping opponents adds to the chaos (when it doesn't bump you way further back then it should.) Tons of cars and tracks, and optional coins to pick up as you drive in order to unlock bonus courses. It gets a bit dull, and the coins can be in nasty spots, but its decent enough fun. Plus it has multiplayer!

The best mobile game.

wii u gamepads dpad kinda sucks, its a bit laggy, and the nintendo bonus modes are kinda eh, but the rest of the game is super fun and chaotic. More games need the pair mode, having players swap out mid-match is fun as hell.
