Nice puzzle. Being my first slalom, I had to solve it 2 or 3 times using different breakins because I kept thinking that the “31″ was the 31st “gate” – when it actually means that there are 31 gates before you get to it. My bad, but a very nice puzzles. Thanks.
I’m horribly sorry; I neglected to put the meaning of the circled number in the description page. That has been fixed. Glad you enjoyed it, and good job for solving a tough one like this as your first.
