Now the most simplest way and one I like to do is once you get Mike the card player you can make some serious money. I simply save beforehand and play a few times, then bet 9,000 potch everytime and before I know it I got 100,000 potch. I just save when I make a lot and play again or if I lose a lot then I restart the game. This could take time if your unlucky but basically it's full proof.

*Note: One card I find very lucky is the 4, if you get an ace it doubles and it has the highest percentage to get a 9. If it goes over just draw again and you should get close to 19.*

Another way I like is by traveling. I start off in a town any town and buy about 5 lottery tickets (4 random, 1 Segmett), get some trade items (make sure you know what ones to sell where to make the most potch) and begin the journey. Each town you stop at buy more lottery tickets, trade, ect... Each battle ground is a way to get more by potch or items to sell in the next town by fighting monsters. Then once you get to the last town on your journey simply go back the same way and do it again till you reach where you started by trading again and cashing in on your lottery winnings. Once your done you should have a healthy sum of money as well as nice level ups for your members. The only draw back is it takes time.
