Bored with no pencil marks

Postby Turtle » Sun Oct 27, 2013 1:51 pm

Has anyone tried making Sudoku harder? I've been solving them one 3x3 grid at a time. No pencil marks. Once you put a number in a 3x3, you have complete that 3x3 1-9 before proceeding to the next 3x3. Would love to know if there are more challenging rules to play by.

I don't like being told what techniques I am or am not allowed to use when solving a puzzle.

I'm the same way at work. Please don't tell me how to do my job. Tell me the end result you want, and let me decide what is the best way to get there.

Are you familiar with the more difficult puzzles common on this forum, but almost unheard of elsewhere?

Sudoku puzzles vary in difficulty over a surprisingly large range. Consider this puzzle, submitted to the Patterns Game by blue:
Code: Select all
4 1 . 8 . . . . .
8 . 9 . . . 4 . .
. 2 6 . . . . 8 .
6 . . 4 . . . 2 .
. . . . 3 . 1 . .
. . . . . 5 . . 7
. 6 . . 1 . 3 . .
. . 2 9 . . . 6 .
. . . . . 7 . . 5   ED=10.5/10.5/10.5

In addition to the Patterns Game, you can look at the daily puzzles in the Puzzles area, where people try to solve the puzzle with a single non-trivial move.

Never heard that "non-trivial" term before. Is it the same as what people call advanced moves, aka non-basic?

Correct, my casual use of "non=trivial" means anything that isn't one of the basic techniques.
