Surprisingly, this has been great outdoor and indoor entertainment for both adults and kids. I bought a larger set for my workplace breakroom and people gathered to watch when it got to be pretty tall and unstable (and competitive). This set I bought for my nieces (ages 6-11) and their friends to use in the backyard, and I'm actually surprised at how much use it gets despite all the other fun stuff they are able to do. This one is not the biggest "jenga" set that I've seen, as it gets to only about 4 feet tall if the game goes on for awhile, but that is good enough for kids. The blocks are definitely sturdy and well made and the kids find it easy to setup. I appreciate that it is simple to setup the game, no instructions necessary, no small pieces, and everyone finds it amusing regardless of skill level, age, or gender. It does take a few minutes to pick up all the blocks and stack them so they fit correctly in the soft-sided bag, but no complaints there.
