Lots of fun and helps get pent up energy out when cooped up in the house. The length of rope is just right to adjust distance between the logs depending on age, height and skill. Some may find the rope limiting but I appreciate it so that they stay together and don't end up in every room of the house.
My kids have played Going On A Bear Hunt, Three Speckled Frogs and many other games with these logs. Sometimes, just walking around in a circle to help focus before homework or when having a family discussion. They're pretty sturdy as my husband has walked on these with heavy boots.
We have tile in our house and I do find they can be slippery on the tile if the kids are jumping and skipping on them. I prefer to have them on carpet.
