Dragan,

I started level 12 with 195137, I got the script taking too long warning the end of 11 and then again when I got level 12 finished, but it hung and never gave me the score or ability to proceed to 13.

I want to thank you for this link, playing this game has given me some ideas for a technique for solving a real world graph problem I'm working on now.
