My five year old daughter just got this for Christmas and has done all of them already. I will have to buy her another set as she is hooked. Its not too complex so she doesn't get bored and the finished picture looks great. The set has squares numbered 1 - 10 and then gems and stars for 11 and 12. All the squares are shiny except number 4 which is used for the skin. This is great for little girls who love sparkle. The set is better quality than I thought and both the picture boards and mosaic squares are durable and easy to handle.
