Summary: This is a fun puzzle game. I expecially like the Stack Jack game. However, everytime I get to the higher levels on that game it locks up and causes my DS to make a loud screeching sound. It sounds like, from other reviews I've read, that this is a common problem.
Summary: I was really looking forward to some nice relaxing puzzle challanges. But instead, I was served up a game that crashes after about 30 minutes. I took it back and replaced it with a new card and sure enough, it still crashes. Tried a different DS....still crashes.
