When playing in solo mode you will most likely get a Sluggish Shroom, which makes the dice block roll slower. When you get to the last six spaces, use it and hit the block one number lower than the desired number. You should land on the rare mini-game space.

The game will now play with all-CPU players, accumulating Stars and opening mini-games without your interaction. Return in a few hours when the game is finished. Repeat this as necessary to obtain Stars and purchase items in the Star Bank. Note: "Faire Square" seems to provide the most opportunities to obtain Stars, due to that gambling options available. Also, the CPU players have a very-high percentage of wins on the gambling games with "Brutal Difficulty" IQ setting. That said, "Brutal Difficulty" should be purchased as soon as it can be, and employee that instead of "Hard" for the CPU IQ. This will build Stars even faster, especially on "Faire Square".
In story mode, play the Snowflake Lake (snowy) level. Each time you finish, you will get 20 Stars in the Star Bank. If you put the bonus on, it will be 23 Stars in the Star Bank. Note: This can work when you put on any amount of turns from 10 to 50. You will even get the Stars even if you do not finish first.

Go to the Fair Square board. When it is night by five per stars. Note: To make it a five per star when it is night, if it is not a five quit until Twila hits a five.

Complete Solo mode as quickly as possible.

Go to Solo mode, then go to the Bowser's level (it has the most spaces). Go as slow as possible (use Slugglish Shrooms and Cursed Shrooms to help). Then, make sure you save a Slugglish Shroom so that you can get the rare mini-game. If you already have the rare mini-game, you will get 50 coins instead. You should get about 20 to 50 stars each time that you play it. Repeat this as many times as needed.

Begin Solo mode and choose any level. Start rolling and landing on mini-game spaces. Keep playing and winning mini games until you have at least 100 coins. Also, land on as many special spaces as possible to get bonus coins. After you have a lot of coins, quit before you reach the end to get credit for your coins and land on bonus spaces. You get one star for every twenty coins you received. Note: Bowser's Tower is a great level for this because you can get knocked back to the start and you can get more spaces in before you have to quit. Also, you will get coins for the Happening spaces that knock you back. Orbs also give you extra coins.
