I bought this for each of my dd's (10 and 11) for Christmas. I also bought one for my dd to give to a friend at her sleepover party a couple of weeks ago and she said they played it until about 3:00 in the morning. She said everyone really liked it.
I found mine at Wal-Mart and they were about $9 each. They come in different colors too.
We like playing the internet game, but I thought the handheld ones would be good for the girls to play in the car.
I played around with the handheld ones, and I believe the internet game does a better job of figuring out what you are thinking-but still fun for the kids.
