Boo Tag

Boo Tag is a mini-game in Mario Party DS. A Boo appears in the play field, and the players must avoid the Boo while running from the player that the Boo has tagged on it. In order to get away from a Boo that's been tagged to you, simply touch another player and the Boo will tag them instead. After a while a second Boo appears. Whoever had a Boo the shortest or never got tagged by one wins.

The play field is small and cramped. There are coins, jewels, gems, gold bars, a sword, and quite a few other items that get in the player's way as they try to run from the Boos. The four players barely fit on the play field, let alone with two boos, making it very difficult to avoid getting tagged.

This Mini-game is also a Duel Mini-Game. The game works practically the same, except only two players are on the field, giving the player more room to escape and run. Whoever has the least amount of tag-time on their counter wins.
