The Data House is a location in Mario Party Superstars located in Village Square. It is operated by Kamek, and it allows the player to perform various options such as listening to music, reading the encyclopedia, and customizing their Mario Party Card. The Data House replaces the Mini-Game House from the original Mario Party game.
The Data House is colored red and features house-shaped windows, a purple door, and a book stand on the left. Inside the house, there are bookshelves, purple curtains, and various other items on a shelf such as a gramophone and an encyclopedia.
The player can view and listen to their music list by tapping the gramophone. Most of the music must be unlocked by performing certain tasks or bought from Toad's Shop. Players can choose to set a music track as a favorite by selecting the heart icon next to the music track.
The player's Game Records are viewed by tapping the bulletin board. Here, the player can view their newest minigame records, minigame win percentage, Mt. Minigames records, and most recent photos. The player can also check their ranking on minigame records when connected to the internet.
The player can read their encyclopedia by tapping a book on the shelf. The encyclopedia's first page features notes and Mario Party series game appearances for characters, the second page features notes and pictures for all home console games except for Super Mario Party, the third features pictures and notes for boards, and the last page features tips for the game. Some encyclopedia pages can be bought from Toad's Shop.
Mario Party Card
Players can view their Mario Party Cards by tapping the card on the shelf. The Mario Party Card records the data of the player's adventures, including their total play time, number of claps performed at the end of online games, number of coins collected, and Mt. Minigames survival mode score. The card also records the player's name, title, and current level. The titles are unlocked by completing achievements. The player's level can be raised by playing and winning in Mario Parties or minigames, and some items in Toad's Shop are only obtainable once the player reaches a certain level. Players can also select their favorite board, minigames, and home console Mario Party game (Super Mario Party is not included in the options). The card's background design can also be customized. There are a total of 15 background designs.
If the player is connected to the internet, their card will be visible to other players.
Unlike the other options, the Staff Credits are only unlocked once the player reaches level 50 on their Mario Party Card. The credits can be viewed by tapping a notebook with camera and Super Star icons. In the credits sequence, the book's camera icon is changed to a picture of various characters celebrating near the Warp Pipe in Village Square, and the book automatically flips around to show various artwork and pictures of minigames from previous Mario Party games. The player can interact with these images by tapping them. The artwork shakes, and the minigame pictures turn into pictures of them in Mario Party Superstars. At the end of the sequence, a "YOU ARE THE SUPER STAR!" sentence appears at the bottom of the screen.
By tapping the crystal ball next to Kamek, the player can view their achievements, shown in the form of stars that surround outlines of constellations. Once the player completes all of the stars that surround an outline, the constellation will appear. By completing stars, the player can also receive titles that can be used on their Mario Party Card. There are two pages of achievements. The first page features five constellations, which depict Mt. Minigames, a coin, a Star, a Warp Pipe, and a Dice Block. The second page instead depicts a crown. There are a total of 60 stars in total.
