These tiles are very easy to snap together and don't come apart easily like some other tiles! Very colorful, fun to play with!! My kids, 5 and 10, spend hours playing with them! Yes! A boy and a girl, 5 years apart having fun together with these tiles! My daughter even makes small houses for her dolls and cute unexpected bassinets for her teddy bear (pictured). We all love these tiles!!!
