New Super Mario Bros. Mii (Japanese: New スーパーマリオブラザーズ Mii, Nyū Sūpā Mario Burazāzu Mī) was an "experience" tech demo shown at E3 2011 for the Wii U. It is based on New Super Mario Bros. Wii and contains new levels, as well as the option for players to use their Miis. This demo was meant to demonstrate the "Off-TV Play" capability of the Wii U, allowing the player to continue playing a game on the Wii U GamePad without having to use a television screen. Players were able to play for up to ten minutes before the game would automatically reset. While the game was only exhibited to show gameplay experience using the controller of the Wii U, New Super Mario Bros. U is "based on" New Super Mario Bros. Mii.
- If the Miis are selected as P1, it will be colored like Mario. If selected as P2, it will be colored like Luigi. If as P3, it will be colored like Wario and If selected as P4, it will be colored like the Blue Mario in Mario Bros., which bears a resemblance to Luigi's light-blue palette swap in the Super Smash Bros. series.
- The Mii's suit are the same used in New Super Mario Bros. U's Coin Battle and Boost Rush.
