FREE: possible free shipping Soduku puzzle handheld electronic game

The listing, possible free shipping Soduku puzzle handheld electronic game has ended.

This is a game that my son's roommate moved out and left, it seems to be working fine but since I don't know much about electronic games or specifically about soduku you are bidding on this as is. I do not have the original paperwork for this game nor do I understand how it works. I think you could probably find a manual online for it but I'll leave that up to the winner. Includes batteries. See more info below for what I found online for it:
