You are a machine putting levels out so often - BTW, that's not a complaint. Spoiler: Sliders Used I only touched 3 sliders to win. Is that right? Thanks
Spoiler That's correct. You only need to get R Bot to the right block, then use the slider to nudge him to the win. P.S. It's just some end of year vacation time that's making me seem so prolific!
I spent a lot of time flipping levers back and forth, trying to force R to go in the direction I wanted him to until it occurred to me that I was working far too hard and came up with the solution mentioned by @gmacpro. That was a lot less painful.
