My kindergarten aged daughter received this as a gift. She loves SpongeBob and loved playing this game.
The game is basically an adventure puzzle solving game. SpongeBob has to interact with people and collect things in order to move on to the next level. I had to help my daughter out with some things, but she was able to generally play by herself. Once she know how to do everything she was able to play by herself.
It's not a great game, but anything for this price that my kids actually play is a good purchase.
My daughters computer is an old dell running XP. It worked on her computer and my computer running Vista.
