Fill Mushroom Bank Easily
Every time players complete a game, the stars and coins from each human player are put into the Mushroom Bank. However, if computer players are filling in, those coins and stars are lost. An easy trick to accumulate lots of stars and coins is to switch all players to human in the last round of the game. (you can do so by pausing and accessing the options menu.) Complete the board and you will be able to keep ALL the stars and coins.
