The Solved list
Solved is this browser’s list of finished puzzles. When you complete a board and the rules hold, that puzzle can show up here.
There is a Solved page as well as the list on Home. Both show what this browser finished. They are not a public board. Nobody else can see them.
An unfinished puzzle does not belong on Solved. That one lives under Continue until you finish it or start something new. Opening a game and walking away does not add a line.
The list is for you: which games you finished, and that you finished them. It is not a ranking, and it does not travel to another browser.
