Just a piece of advice I ran into when solving this problem.

The ray exiting through the opening, does not count as a hit.
(It does say this in the question, but I missed it)

EDIT: My program gets the same results for the 2nd, 9th and 33rd, but my answer isn't correct!!!

(0.006 -10.000)

This is the last point I get, rounded. This point is the 160th-170th point I get, hopefully I'm not giving too much away here. Am I anywhere close?

EDIT*: Just realised the problem, pretty much as soon as I edited this point. Embarrassing! :\

EDIT**: Solved :D

please tell me what the problem was. I'm in the exact same situation as you and have no idea

Edit: never mind, I also figured it out instantly. Life would be so much easier if they made holes on both sides..
