This game is new for 2018 and in addition to be labeled a STEM challenge, it is also great fun! It seems like a simple game, and it is, but the learning that's going on too is wonderful for the younger crowd. I have a 5-year-old nephew who is going to love it! It comes with an instruction booklet to help you set up the pieces in various ways with increasing challenge. Players pull the pendulum back and swing to hit the ball that is perched in front of it, hoping to knock over the stacked pieces. You can use said challenges, or design your own. This is the kind of game that gets addicting. You play once, do a great job (or not, ahem) and want to try again and again and again. We have a lot of fun with this one, and I think it would be a welcome gift to give for the holiday season. Learning Resources offers this and so many other great learning ideas for kids that are enjoyable too.
