These achievements require that you finish a total of 10 daily crossword puzzles. Daily crosswords are in their own category and only one can be completed per day. So at a minimum, this game will take ten days to complete because of this achievement alone. As of now, exploiting the clock on your PC is not an option because daily crosswords are not available offline. Each day, join or create the new daily puzzle (make it Public) and complete it or exit immediately. As long as you come back and click on it once it was completed, it will count. There is no visible counter for this achievement. Just continue completing daily puzzle until it unlocks, or keep track yourself.
