Age recommendation incorrect

I work professionally in a kindergarten with children aged 3-6 years. We have both the junior and the crazy labyrinth maze in our group.
I must say that preschoolers can play the crazy labyrinth very well and that in this case, the junior Labyrinth much is too easy for preschoolers.
I recommend the Junior Labyrinth therefore for children aged 4-5. and the crazy maze (actually from 8 years), I recommend from 5 1/2 years.
