Gameplay
The player must use his/her as a flashlight. In the intro, the player sees the Boos. The lights then turns off and the player then must find the Boos in the dark in three seconds by rubbing the Touch Screen with the to find the Boos. If the player finds all of the Boos, he/she moves on to the next level where more Boos are found. After level fifteen, the amount of time gets reduced by one second. If the player can't find all of the Boos in a certain amount of time, they lose the game and get a Game Over.

The Boos in the game follow basic physics, bouncing off walls and each other at angles relevant to the angle they hit them at. By observing the Boos at the beginning, the player can predict where they end up.

In the mini-game'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 collected, a new round begins. The player with the most Boos at the end of the game, wins.
