Time Trial

In the Mario series, the phrase time trial is synonymous with the Mario Kart series, wherein it is a game mode that involves racing around a track of the player's choice in order to achieve the fastest time. It is a one-player mode. They contain a replay feature that allows the saving of the best time such that it can be replayed in the form of a ghost that can be raced against. In later Mario Kart games, there is a "Staff Ghost" already in the game for each track, a saved time created by a member of the Nintendo staff.
