If you come across a Jenga game at Goodwill or have one you no longer use at home, hang on to it and use it for building blocks. They are nice, smooth blacks perfect for stacking. My son loves for use to build him crazy towers to knock over. You can also lay them out, side by side, to make a road or set them up on the narrow sides and create a fence for a zoo. They are less painful when they fall on you toes too. The possibilities are endless and who doesn't love inexpensive, yet fun toys for their kids!
