this is a number place and I tried to break up the different size boxes by putting extra spaces between them, in row one the center box contains 5 squares in row two the center box contains 4 squares this is repeated in row 8 & 9 first 4 squares then 5 squares. row three has 3 squares in each "box" row 4 is 4 squres,l square, 3 squres and 1 square the top left and bottom right are the traditional 9 square box, if you need more details, let me know, oh right each "box must contain 1-9 as each row must also. thanks

Hi stevens,

This is the how your puzzle would look liked after using the tips found in "How to ask for help" thread [assuming a non variant puzzle]. you can fiddle with it to cange boxes shapes.....

[Edit: I just noticed that Stevens post SEEMS to indicate that it is some kind of variant].

This thread will help in posting killer type puzzles.

Yep, must be. At any rate, the puzzle you posted has a messed up col 5:

Just a thought - when posting their puzzle I wonder did stevens leave out clues for r3c9 and r4c5? This would then make the puzzle symetrical.

I wonder did stevens leave out clues for r3c9 and r4c5?

Wouldn't matter. The puzzle is already invalid. More numbers can't make it valid.

Nope. Surely it is some variant following rules we don't know. Time to unscribe to this thread.

"..More numbers can't make it valid..."

Good point Mac.

".. .Time to unscribe to this thread. "

Don't mind if you do Mac!. On second thoughts I think I will too.

Stevens - if this is a number place, aka Killer Sudoku, try the Variants forum and use the thread suggested above about posting or at least let us know the position and value of the cages e.g. r1c12 = 15 meaning that r1c1 and r1c2 add to 15 (7+8 or 6+9) etc.

[stevens]

here are the known's c1r2-1 c1r3-6, c1r7-5, c1r8-8, c2r3-8, c2r6-6,c2r7-2, no known #'s in c3 c4r2-2, c4r5-3, c4r8-7 c5 r1-1, c5r5-2 c5r9-6, c6r2-7, c6r5-6 c6r8-5, no known #'s in c7, c8r3-2, c8r4-7, c8r7-8, c9r2-6, c9r3-9, c9r7-3, c9r8-1

[CathyW]

Er ... thanks but that doesn't tell us any more than the grid you posted above. In order to help you with a killer sudoku we need the cage sums, not just the numbers you've got. If it's not a killer sudoku (sum number place) then please explain what type of variant it is.

Is it an irregular sudoku i.e. where the 'boxes' are not square? If so, you need to explain more clearly the pattern.

[stevens]

I have done some research and think it is called a geometry sudoku, or latin squares puzzles, they can be seen here=http://www.maa.org/editorial/mathgames/mathgames_09_05_05.html the one I'm trying to solve is like the 8th set of puzzles, further if you go to http://www.geocaching.com/seek/cache_details.aspx?guid=91b8aba1-9832-4c4d-97d8-ac09f984c8ab, it is puzzle #3 that I'm having the trouble with, any help at all is really appreciated.

[CathyW]

This is an irregular sudoku! (btw the link doesn't work with the extra comma at the end). I've printed out a copy to have a go - will post again if I get anywhere.

The boxes are defined:

1. r123c123
2. r1c45678, r2c4567
3. r1c9, r2c89, r3c789, r4c678
4. r4c1234, r5c1234, r6c1
5. r3c456, r4c5, r5c5, r6c5, r7c456
6. r4c9, r5c6789, r6c6789
7. r6c234, r7c123, r8c12, r9c1
8. r8c3456, r9c23456
9. r789c789

[r.e.s.]

That's a jigsaw sudoku apparently taken from Michael Mepham's site.
I'd used it as an <example to illustrate the Law of Leftovers (LoL)> ...

[CathyW]

OK Stevens - I solved the puzzle! So here's a walkthrough of the steps taken, but first a picture to show the shapes of the boxes.

I didn't knowingly use the "Law of Leftovers".

First look for any singles:
Only one place for 6 in column 3 (r4c3), and in box 5 (r7c4)

I had to enter candidates but then locked candidates proved very helpful:
Box 4 - 2 must go in r4c1 or r6c1 -> Box 1 r1c3=2 -> Box 8 r9c6=2 -> Box 9 r8c7=2 -> r8c8=6 -> r1c7=6.

Row 1, 7s locked to r1c12 -> r3c5=7
Row 2, 8s locked to r2c57 -> r1c9=8 -> r6c6=8 -> r4c5=8 -> r2c7=8 -> r5c3=8 -> r9c4=8
Box 6, 3s locked in r6 -> r3c6=3
Box 6, 1s locked in c8 -> locked in box 3 c7 -> r4c6=4 -> r1c6=9 -> r7c6=1.

Naked pair (45) in c4 -> another pair (19) in c4.
Naked pair (45) in r3 -> r3c7=1

Hopefully you can manage the rest but the complete solution is in tiny text below (copy and paste to text editor and enlarge the font to view).
