Is there an algorithm categorizing the puzzles depending on average times to solve. Some of the extremes are easier than hard. And the hards keep getting tougher.
Would really love one more category - wicked or diabolical. Ones that'll drain the minds and batteries of avg joes like us

Some of the Extremes are easier than Hard. I have a suspicion that the more i play Hard the tougher its getting. I had 10 under 10 minutes then under 9, 8, 7. But after playing 100 odd games i still cannot better my earliest timings of 6 minutes. Couldn't be getting worse, the more i play?
