How do you get mini-games in mario party 3?

Answer 1

You get mini-games by the following:

4-player Mini-games, 2vs.2, 1vs.3:

When a turn ends in Party mode, you play a mini-game.

Battle:

Land on a battle space in Party Mode.

Duel:

Land on the same space as a player in Party mode or challenge them to a duel with the dueling glove item.

Rare:

Dizzy Dinghies - Unlock all other mini-games

Stardust Battle - Complete Story Mode

Mario Puzzle Party Pro - Beat Game Guy's Room (You can go into game guy's room after you beat story mode)

Item:

Land on an item space in Party mode. Sometimes, instead of playing an item mini-game, you will be asked a trivia question instead.
