Other than the standard single player mode, New Super Mario Bros U includes a special Challenge Mode, which tasks players with completing specific objectives. There are four single player modes here: Time Attack, Coin Collection, 1up Rally and Special. Boost mode challenges require two or more players, one using the Gamepad and all the others using Wii remotes. Once a challenge is completed a replay is automatically saved.
Pretty much as the name implies, players will have to clear a stage in the fastest time possible. This means that you really must be perfect, without making any mistake. Here are the requirements to get a Gold, Silver and Bronze ratings on all the trials.
