We've made it to the computer circuit puzzle and there's nothing that indicates what the object of the puzzle is. I'm thinking that the color of the "wire" must match the color of the nodes at each end to create a path from left to right. But some nodes are only half-nodes. Is there a way to rotate the nodes?
If someone could get us started on this one, I'd appreciate it. Jenny, could you send me a link to the Spanish walkthrough if it has this puzzle on it?
