First of all, I’m still working on Puzzle 3. It’s not working out for some reason 😦
I have made ProgressTM on it. I finally got past the thing that I was stuck on for a long time (yay!), so the rest of this should be going at a much faster rate. That being said, I don’t think it will be ready by the time everyone in the US is on Winter Break.
There will probably be two rounds of testsolving, though puzzles will (mostly) remain the same between each round. Round 1 will not include metapuzzles and all that stuff, though Round 2 will include the whole thing. Participating in R1 does not mean that you can’t be in R2. Just saying.
More details might be published later. But don’t expect that for a long time.
