Is there a way to cheat?
I dont see how. You cant copy a puzzle because I am certain admin has set up codes to prevent that, and copying would be the only way to cheat... copy and paste to a solver of some sort? There is no way I can see how that could happen.
No, I think people are just really fast typists, and have amazing pattern recognition abilities. Possibly excellent memories to authors names as well. I do agree however, that guests should be allowed to see their record times, I played for months and set a few, I did not know they affected the actual competition for registered members until joining. I also think guest scores should not be counted in the record times.
Thank you for letting me speak on this.
Be well all.
