It's as good a way as any. There are no hard and fast rules to learning the game so whatever suits you is fine. For me, practice is the key. I'm not familiar (as far as I know, I could be using the techniques described on this Forum and elsewhere without being aware of it) with techniques or their names and I've never gotten further than Pappacom's Fiendish level - which suits me at the moment. I do at least one puzzle a day, on paper, and that suits me.
As MCC stated, post the puzzle you're stuck with and where you are stuck and someone will give you a hint. It's easier to do this than to list a lot of techniques, especially when it's so hard to grade different puzzles. What I mean by that is, what's Hard for Michael Mepham - no disrespect intended - may not be Hard for Pappocom and the techniques listed for Pappocom's Hard grade won't be any use to you.
I have noticed from my time here that mostly everybody gets stuck with one of their puzzles at one time or another and someone is always on hand to help out.
Post it like this :
- Code: Select all
Copy & paste this grid into Word, (for example)
. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
------+-------+------
. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
------+-------+------
. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
Replace relevant dots/periods with numbers and then paste that grid back into the forum embedded in "code" tags (which forces fixed width characters).
Just makes it easier to read. Code button is at the top of the screen when you press reply (ie, you copy and paste the above grid into Word, replace the dots with the numbers you have, then back in the Forum, click reply, press the Code button, copy and paste the grid with numbers and dots from Word back into the Forum, then press the Code button at the end of the grid, so that the grid is embedded into the code tags). It'll look like this on your reply, except that there will be some numbers on the grid (obviously!) :
- Code: Select all
[code]. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
------+-------+------
. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
------+-------+------
. . . | . . . | . . .
. . . | . . . | . . .
. . . | . . . | . . .
[/code]
I hope that's clear!
