Ghost Guess

From the Super Mario Wiki

Ghost Guess is a 1-player mini-game found in Mario Party. The player wins by finding the Leader Boo. The Leader Boo can be found, for its movements happen slightly before all of the other boos, who follow. Once the player finds it, he/she will kick the boo, and if correct, the player will get 10 coins. However, if the player chooses the wrong boo, or the timer runs out, he/she will be encircled by the boos, and will lose the game.
