Tons of freebies.
This puzzle is "easy" to "very easy" up to here:
| Code: |
+--------------------------+--------------------------+--------------------------+
| 5 4 3 | 8 1 27 | 79 6 29 |
| 8 279 1 | 79 4 6 | 57 3 25 |
| 279 6 29 | 3 279 5 | 1 8 4 |
+--------------------------+--------------------------+--------------------------+
| 6 5 4 | 2 3 1 | 8 9 7 |
| 3 279 29 | 5 79 8 | 4 1 6 |
| 79 1 8 | 79 6 4 | 2 5 3 |
+--------------------------+--------------------------+--------------------------+
| 124 8 6 | 14 27 3 | 59 47 59 |
| 249 29 5 | 6 8 27 | 3 47 1 |
| 14 3 7 | 14 5 9 | 6 2 8 |
+--------------------------+--------------------------+--------------------------+
|
At this point, many possibilities:
Most obvious, the 14 UR
Without the UR,
- coloring in 7: a skyscraper in rows 3 and 5.
- or maybe that innocent looking x-wing (9) in cols 3 and 5, which reveals an xy-wing?
- or, best of all, that amazing w-wing triangle (9) r2c4=r6c1 , r6c1=r5c5, r5c5=r2c4
Took me longer to post this message (well, yes, and to see what else was there ... ) than to solve the puzzle. No kidding.
A "one coffee" puzzle... |

Indeed; I do like these puzzles where the basics clear away quickly, leaving me to concentrate on whatever advanced techniques there may be.
I spotted an x-wing - not enough to solve the puzzle on its own - and a UR - no doubt there are many other possibilities.

Find one of the possibilities and you won't need the x-wing or ur. It will leave only singles.  |

| For me it was the ER in box1 although one could claim a W-Wing to achieve much the same end. Of course the ER is more powerful in that a strong link rather than duplicate pairs are all that is needed! |

Here is what I saw: | Code: |
*--------------------------------------------------*
| 5 4 3 | 8 1 27 | 79 6 29 |
| 8 29-7 1 |*79 4 6 | 57 3 25 |
| 279 6 29 | 3 279 5 | 1 8 4 |
|----------------+----------------+----------------|
| 6 5 4 | 2 3 1 | 8 9 7 |
| 3 *279 29 | 5 *79 8 | 4 1 6 |
| 79 1 8 |*79 6 4 | 2 5 3 |
|----------------+----------------+----------------|
| 124 8 6 | 14 27 3 | 59 47 59 |
| 249 29 5 | 6 8 27 | 3 47 1 |
| 14 3 7 | 14 5 9 | 6 2 8 |
*--------------------------------------------------*

Some call it a turbot fish; I call it a 2 string kite or kite.
Leaves only singles. |

| UR {1,4} in r79c14 eliminating 1,4 in r7c1 solves the puzzle. |

Yes OR 79s in boxes2 and 4. Either w wing gives pretty much the same answer! |

| A skyscraper in column 2 solved it for me. I thought sure I'd find a xyz with all those 2, 7, 9s all over the place. |
