ooh nice!
NEW: Puzzle Features Get a New Look!

This project was focussed on the interface, and you're right, we didn't make any changes to back-end logic for serving puzzles as part of this.
I agree with you about the issues with Learning mode, and in particular with respect to previously-encountered problems. I think there is a better way, and it's already being looked at; I am hopeful that we can address it soon! Thanks.

yeah, we've all read that before. when CS, et al asks "...why didn't they renew their membership,..", you can tell them this is one reason, among others...
[edit}: the fact that you allow bugs to a) to pass through "QA" , b) to pass through BETA and c) to persist in the real world is irresponsible.
Hey, all! We just released a new version of Puzzles to everyone! Our goal was to make Puzzles cleaner and more modern looking - and more fun too!
You will see a new index at the main Puzzles page. This gives a quick intro to all Puzzle features, and one-click access to each.
The individual features work as they always did, but you'll notice improvements to the interface everywhere (we hope!).
If you like to be mindful of your time in Rated Puzzles, you'll want to check out the new timer:
When the circle fills in completely, your Target Time is up! (Target Time is how long someone can take to solve the puzzle and still get a perfect score, given their current rating.)
We hope you love the new face of Puzzles! Please share issues or other thoughts below - or use the "?" icon at the lower left corner of the page to Report a Bug or Make a Suggestion. Thank you!
