Very open ended. I can't tell you the amount of things my children have pretended these steps to be. Ice cream cones were my biggest surprise! So many builds, "train," stairs, marble runs, very fun. Would highly recommend getting both the primary and pastel colors.
It adds fun element in ball run set ups for play
I wish these came with more pieces fro the price but my kids cannot stop playing with them. Perfect for ball runs and creative building.
