http://sourceforge.net/projects/jrisk/ is a game that looks like the real game. I downloaded it for my Mac and it seemed cool.

I will take a look at it when I get home.

Thanks

This is a flashcard program to learn Japanese vocabulary. It has word groups for the Japanese Language Proficiency Test (JLPT) levels 1-4 and 13,000 extra words that are considered common. It could easily be modified to use other types of flashcards.

This is in beta stage now and is just meant to show what it will look like. It should be done in about two weeks.

You must have .NET 3.5 installed (it is available under Windows Update if you don't already have it).
