I'd like to request an option to play practice puzzles.
What do you mean by practice puzzles? What would be different?
Currently, there is not an option to play puzzles without it ranked and tied to my official puzzle score. I would like an option to play those puzzles without it being officially recorded by the site.
That number you see isn't the rank, but rather the difficulty rating of the puzzle. The number is there to show you how hard the puzzles are and is calibrated so that you get puzzles of the right difficulty. I think you can play logged-out, but you would get really easy puzzles. Also, the website doesn't log puzzles for more than 3 weeks, if that is what you are concerned about.
You can't post in the forums yet. Play some games!
