You're right. Perhaps it is possible to finish 30 hard puzzles in 28 minutes or less and maybe with more practice I too will get those elusive badges one day. Thank you.
Well, I've never done 30 hard puzzles in 28 minutes, nor has anyone in my group. I think the last "take the hard road" - the person who placed first (in my group) did it in 45 minutes. ...it wasn't me. :(
I was just offering some basic tactics that I used to collect 1,2,3 badges - without cheating. Sorry if it offended you.
