My kids LOVE Mario Kart. My 3 (aff) and 7 year olds play against one another, play against us, and play by themselves. That is why when K'NEX contacted me about checking out their Mario Kart Wii Building Sets I had to say YES!
Madison built the Mario and Stand Kart Building set. When I say built, I mean she did it without any help. It is for kids 6 and up, and she is seven. There are 66 pieces, and though it took her a bit, she was able to handle it with the directions (which are all in pictures). The coolest part though has to be that if you pull it back (when on the floor), the cart takes off and drives down your hall! 🙂 My kids definitely thought that was a coolest part!!!
Will and my husband built the Luigi and Standard Bike Building Set. It didn't take them long, and my son has been playing with his motorcycle ever since! He even sleeps with it!
These are both toys that my kids have consistently played with since we got them. They are durable, easy to put together, and best of all, fun to play with. I can only recommend them!
