Not long, I'm sure. My son is 10. I figure I have about 5 years before my cool factor turns icy in my son's eyes. I've got to maximize our play time.
My brother and sister-in-law play Draw Something, an iPad, iPhone, all around smart phone app, that allows you to draw pictures for friends to guess. My niece who's four, loves it. She loves checking for new drawings to guess or watching a friend solve a drawing she and her Mom sent. Part Pictionary, part Jumble, you play by connecting with other players via Facebook or email.
It's no wonder the game shot to the top of the apps charts. After your friend guesses the picture you drew you get to watch a quick video of the drawing creating itself and see at what point your friend got it. You can skip that part, but it's fun to see. It's even more fun to draw.
Speaking of which, it's my turn.
