We have two sets, my daughter is asking for the third. She has been playing with these building blocks since she was 5 years old and still enjoys them when she is almost 7 years old. She used these kits to build some amazing forts with doors, gabled roofs, window openings, and fenced backyards. I help drape blankets over the structures she builds and we used safety pins at one point to help the blankets fit better. Each kit has a light, so the two lights she now has are perfect for illuminating her larger forts. She reads to her dolls and generally has a blast in each new fort configuration.
