Hide and Boo Seek

Hide and Boo Seek is one of Yoshi's minigames in Super Mario 64 DS and a Puzzle minigame in New Super Mario Bros. Despite being one of Yoshi's minigames in the former, this minigame features Luigi as the playable character. The name and gameplay of this minigame are based on the game.

Gameplay
Luigi must use his flashlight to find the Boos in the mansion. The player must use the stylus as a flashlight. In the intro, the player sees the Boos, which follow basic physics, bouncing off walls and each other at angles relevant to the angle at which they hit them. By observing the Boos at the beginning, the player can predict where they end up. The lights then turn off, and the player then must find the Boos in the dark in three seconds by rubbing the Touch Screen with the stylus. If the player finds all of the Boos, the next level starts, where more Boos are found. After level fifteen, the amount of time gets reduced by one second. If the player cannot find all of the Boos in a certain amount of time, they lose the game and get a Game Over.

In the minigame's multiplayer version in New Super Mario Bros., there are more players and more Boos. Players have fifteen seconds to get as many Boos as possible. When all of the Boos are found, all of the Boos are counted and a new round begins. When the timer reaches zero, all of the Boos that have been found are counted, and the player who has the most wins.
