I used to only do the daily puzzles, but some of the guys in my club are doing them, so I started 3 days ago. Since I wasn't doing them before, I can't really miss what I never saw. It does tell you the difficulty after you solve it. I find these puzzles fairly predictable. I ignore the time bonus because getting it right gets you more points than rushing and possibly getting it wrong. I have over 16,000 pts in the last three days, but I have a long way to go to catch my friend Ken, who has over 150,000 pts.
Why has the difficulty ratings of the puzzles been discontinued?

I think I preferred the old way, where each puzzle was designated a difficulty rating. The newer way, is fun but, do I care about "Wood" and "Stone"?
I'm just curious how you more experienced folks feel and if I'm missing something....
Other than skills.
