I know what you mean. This puzzle has not ceased to challenge me. I actually got started a couple of days late, so I'm sure someone else will win, but that doesn't stop me from enjoying a good challenge!
I tried to get started at the beginning, but sucky ISP meant I really didn't get much real chance to focus on it until the Wednesday. Have made huge progress since then, but like you guys, are starting to come to a stand still. It is SO frustrating as the next stage seems tantalizingly close when I try to put it all together.
We're happy that we are able to keep challenging you guys. We sought to create a contest that would give a real test to people at all puzzle skill levels, but was still winnable and logical each step of the way. Continued good luck.
The funny thing is, the first master I thought I had a solution for is still unsolved for me (even though the answers seem correct and obvious)... and I know that the general approach is right coz I have solved enough others
I keep solving things but it seems like every time I solve something I just get more and more discouraged. And so many have been solved already it doesn't seem worth it to keep trying when I'm just coming up with dead ends. :/
