Your puzzle has 15 solutions - did you enter all the clues and your own numbers correctly?

There's only one place for a 1 in box 3 (hidden single), and the location of 1s in box 8 will eliminate some from box 7 (locked candidates)

The location of 3s in box 1 will eliminate some from box 7

Location of 6s in box 2 will eliminate from box 5

Once you've got all those, the only next step is a guess, and see if you can proceed from there through to one of the solutions.

Shazbot - I think this puzzle does have just one solution.

Armageddon – you have found all the initial singles so far.

You need to use a different method to get past this stage.

The methods are explained at the Simple Sudoku website – click on the blue words.

If this is where you are, the next step could be -

The triple in row 8 = 237 237 37 lets you remove all other 2s 3s and 7s from row 8.

You will probably be able to solve the puzzle yourself after that, if not ask again.

Ah, I know what happened... Trying to be clever, I copied the image from the original post, pasted into SadMan Sudoku (trying to save time dubbing), then copied from there into Simple Sudoku. Didn't realise SadMan Sudoku misread the 4s as 1s (I didn't raise an eyebrow at the bright pink squares all over the grid), and when I pasted THAT into Simple Sudoku it only took the first 1 in each group that it found. Meant some cells that should have had 4s had 1s instead, and some numbers were just left out because you can't have two of the same in a group.

Well, I'll know to be a bit more careful about THAT one! Thanks em - when I went to the trouble of MANUALLY dubbing, it was a pretty easy one to solve.

If you use locked candidate 3s (from box 1) and 4s (from box 8) you'll be left with a naked single (7) in box 7. It's easy from there.
