Anyone here likes to play Puzzles...
and they are actually good and that?
I have some unsolved, and my brain is not capable to crack them
Do you mean Bitcoin puzzle problems? (no)
If you count sudokus as puzzles too, then yes.
I think I am pretty good, but I still like to play at levels easy/medium and make them more difficult by adding extra challenges.
Examples:
-by fully filling one 3x3 grid at a time
-solving only full lines/columns at a time.
I am also planning to try to do a very easy soduku completely in my head before filling it to a paper, but haven't done it yet
(completely in my head. Without seeing the paper)
