I think I can handle this: 168 pieces, for ages 3+, lol!

They worked with our regular legos, tight fit though. came with like 6 marbles, I think the track would fit standard size marbles too but not totally sure. You will need a lot more legos though as you have to build it very tall and keep circling the marble around as most of the pieces are curved marble track. I think it would be a great game to have 2 or more children see who can build the tallest towere. Wish they have miniture lego people to put on it like a slide. I tried putting a 1 by 1 leg to a lego head but it wouldn't go down the marble run at all. Very challenging as I had to keep adding on more blocks to make it taller so you add on more marble run pieces. Deinetly will keep kids bussy. Great deal for the product and good size box for giving as a present.
