To change the built-in puzzles, here is a very nice puzzle winter theme. In positive: - There is a small working motor to position the parts they do not slide over each other. - There is a work of observation to find the reason for the room. - There are different levels of difficulty, some parts are harder than others as the mountain area for example. I do not see any negatives. My 3 year old daughter and a half like this puzzle and seem to do it without too much difficulty except for the positioning of 3 parts that look a bit on the side of Heaven. The price is reasonable, I will buy him probably other seasons.
