Which Mario Kart game was released on Nintendo Switch in April 2017?

Mario Kart 8 Deluxe was released for Nintendo Switch in April 2017.

It launched on April 28, 2017, less than two months after the Nintendo Switch debuted on March 3. The game is an enhanced version of Mario Kart 8, which originally appeared on Wii U in 2014. Deluxe includes the original game's downloadable content, revised battle modes, additional characters, and gameplay refinements.

A common mix-up is confusing the game's title with Mario Kart 8. Mario Kart 8 is the Wii U release, while Mario Kart 8 Deluxe is the Switch version. It was not a brand-new numbered sequel, but a substantially expanded rerelease that became one of the Switch's most successful games.

Mario Kart 8 Deluxe later received the Booster Course Pass, adding 48 more race tracks in waves from 2022 through 2023. That post-launch content further expanded a game that already included 48 courses in its original Switch package.
