Patience ...
Curtis has the info for the last 3 puzzles, but he has a lot on his plate and it takes a while to set up and test the puzzles on the bash server before we can go live with them.
There's a lot more involved with puzzles than the simple submittal forms used for most contests and Curtis has a business to run at the same time.
Just keep watching for them - each one will be active for 24 hours once it's activated.
