The listing, Learn chess for nintendo ds (read first) has ended.
This game occasionally works, but it also will sometimes start up, make a buzzing sound and turn off. I have tried it in other systems, and one worked fine (otherwise I wouldn't put this up), on others the game was defective.
I'm warning you now, while the game may work, there's a pretty decent chance it will not work at all, and therefore, only worth parts (I'm sure there are uses)
Remember- this game might not work, it may make buzzing sounds, or quite possibly, not even turn on, and your system might not even recognize that a game is even in there.
If you bid you are stating that you have read, and understand, what you may be getting, and this is your own choice.
