It appears to me that the puzzle selection in CoC is not entirely random. I suspect there’s some metric involved in the puzzle selection algorithm favoring easy to solve puzzles.
This leads to the situation that
- A few puzzles are repeated over and over
- The average difficulty of selected puzzles is very low (I’d even call the median “too easy”)
- New community submissions show up more often (and then “disappear” after a few hours)
Anyone else observing this? Any plans to adapt the “random” selection algorithm?
