This is a true marvel to behold! No batteries! No electricity! Yet, it actually computes like a computer. It is fun, challenging, and educational! I'm 66 years old and I'm having a blast with mine! It's such a brilliant concept: Sixty "puzzles" where YOU figure out where parts fit into the flow and complete a functional device which delivers the required result. An excellent hands-on experience and a complete joy to watch your solutions come to life using only the power of gravity. I highly recommend this for anyone who loves to explore how things work and why. A beautiful gaming experience!!!
