I'm used to a system where everyone starts a solution from the same place in the puzzle eg. after the SSTS (Simple Sudoku Techiques Set) position. In the puzzles being posted daily here, is everyone running the original puzzle thru the same basic moves before solving the puzzle? And if so, what are they?

So far, if I have entered any solution here, I've been simply using someone else's grid that shows the puzzle with pencilling and no other solution marks in it.

Thanks for any info.

Don,

I found the following definition of SSTS on the web today:

{Naked Single, Hidden Single, Naked Pair , Locked Candidates , Naked Triple , Naked Quad , Hidden Pair , Hidden Triple, Hidden Quad} , [ X-Wing , Swordfish , Simple Colors , Multi-Colors , XY-Wing ]

The moves in the curly brackets are what I understand to be "basics". The challenge of these threads appears to be to find a single non-basics move (after basics have been applied) after which the puzzle is solved with the only following moves being more basics but preferrably singles only. The terms in the square brackets are the elements of SSTS that would not be applied prior to "the move". If the full SSTS as above were applied then many of the puzzles in these threads would be solved within SSTS and there would be no challenge . The current puzzle would be a case in point - there some simple coloring moves that would complete it within SSTS. I also wouldn't include Jellyfish in basics.

Thanks Leren. That's a nice specific clarification.

fwiw: I know that the typical puzzles here are straightforward enough for a nice 'daily solving challenge', the more occasional SAM (Suggest A Move) puzzles are an attempt to present a bit of an extra challenge beyond the moves in the square brackets. However, no matter which type of puzzle, it's great to see a nice consistent group of solvers on this forum.
