Re: Jesus Jesus am I ever stuck

So do you want the answer, or a hint? This is my first post and I haven't looked at any others yet, why read posts when you can do a Suduko? Anyway, I don't know the naming methods you use. You should be able to figure out box 8. The middle one of the bottom 3. Of the missing 7,8 & 9 there is only one place where the 8 can go.

Invalid Puzzle

This one is pretty messed up.

There are two <5>'s in C5.
There is no place for a <3> in B9.
There is no place for a <3> in R8

I like to fix broken things.

Here is a repaired version:

Code: Select all
`. 4 8|1 . .|. . 5. 3 1|. . .|. . .5 7 2|. 8 4|1 . .-----+-----+-----4 8 6|5 1 7|. . 32 9 5|4 3 8|6 7 13 1 7|9 6 2|4 5 8-----+-----+-----7 5 3|2 4 1|. . 68 2 .|. . 6|. 1 .1 6 .|. . 3|. . .`

I removed both conflicting 5's in R2C5 and R9C5.
I removed the 1 in R9C9 which conflicted in all 3 units.
I first removed the conflicting 6 in R8C5. Removing the other 6 in column 5 would have been useless. Without the 6, the puzzle has 4 solutions, so it needed another clue. One of the 2 other positions for 6 in box 8 would not cause a unique solution, but R8C6 does.

So here it is. Fixed using logic only. The remainder of this puzzle can be solved with singles.
