The player begins "Mario's Time Machine" in Bowser's museum. The museum is the main hub, where the player obtains the artifacts and directly accesses all the game's levels (which consist of locations on Earth in different time periods) using the Timulator. In the Super NES and MS-DOS versions, for each artifact, the player is given the year and place it originated from. For example, the player learns that the "Apple" artifact originated from 1687 Cambridge. The player can then time travel using this information; time traveling itself is a minigame in which Mario surfs through a wide ocean, collecting mushrooms. Collecting enough mushrooms will transport Mario to the time period and location programmed into the Timulator. The player is given a short document describing the life and notability of the historical person associated (e.g. Isaac Newton), but the document itself has some of its terms missing. The player thus is required to converse with the non-player characters depicting the local denizens of the time period in order to learn various facts and be able to fill in the blanks. The player chooses the words from a list of pre-determined words; if the player incorrectly fills a blank more than twice, he is sent back to 1993 and is required to try again. When the player fills all the blanks correctly, he can then successfully return the artifact to its original owner. In the game's ending cutscene, Mario manages to confront Bowser, who then steals back the Timulator to make his escape. At this point there are three possible outcomes based on the player's overall performance: in the worst outcome, in which the player fails to return the artifacts quickly enough, Bowser successfully escapes to an area known as Paradise; in the other two outcomes, the Timulator experiences mechanical overload, sending and trapping Bowser in the Jurassic era.
