Can't find a single step. Five steps Code: |
+-------------------+--------------------+--------------------+
| 5 39-4^ 37-4^| 17 49 1279 | 8 1279 6 |
| 8 49 47 | 5 469 12679 | 19 3 279 |
| 1 6 2 | 8 3 79 | 4 79 5 |
+-------------------+--------------------+--------------------+
| 7 18* 9 | 4 2 16 | 5 68* 3 |
| 3 2 6 | 9 8 5 | 7 4 1 |
| 4 5 18 | 136 7 136 | 2 69-8 89 |
+-------------------+--------------------+--------------------+
| 9 34^ 34^ | 27 1 8 | 6 5 27 |
| 6 7 18 | 23 5 4 | 139 129-8 289|
| 2 18* 5 | 367 69 3679 | 13 178* 4 |
+-------------------+--------------------+--------------------+
|
Step 1: X-Wing on (8)r49c28 => - 8r68c8 and
Step 2: Type 4 UR(34)r17c23 => - 4r1c23
Code: |
+---------------+--------------------+--------------------+
| 5 39 37 | 17 4 1279 | 8 1279 6 |
| 8 a49 a47 | 5 69 12679 | a19 3 29-7|

| 9 34 34 |e27 1 8 | 6 5 f27 |
| 6 7 18 |d23 5 4 | c139 129 289 |
| 2 18 5 | 367 69 3679 | b13 178 4 |
+---------------+--------------------+--------------------+
|
Step 3: (7=491)r2c327 - (1=3)r9c7 - r8c7 = (3-2)r8c4 = r7c4 - (2=7)r7c9 => -7r2c9
Code: |
+---------------+--------------------+--------------------+
| 5 39 37 |a17 4 1279 | 8 279-1 6 |
| 8 49 47 | 5 69 12679 | 19 3 29 |

| 6 7 18 | 3 5 4 | 19 129 289 |
| 2 18 5 | 67 69 679 | 3 c18 4 |
+---------------+--------------------+--------------------+
|
Step 4: (1)r1c4 = (1-6)r6c4 = (681)r649c8 => - 1r1c8
Code: |
+---------------+------------------+-----------------+
| 5 39 37 | 1-7 4 1279 | 8 a279 6 |
| 8 49 47 | 5 6 279 | 1 3 29 |
| 1 6 2 | 8 3 79 | 4 b79 5 |
+---------------+------------------+-----------------+

| 6 7 18 | 3 5 4 | 9 12 28 |
| 2 18 5 | 67 9 67 | 3 18 4 |
+---------------+------------------+-----------------+
|
Step 5: (7)r1c8 = (7-9)r3c8 = (9-6)r6c8 = (6-1)r6c4 = (1)r1c4 => - 7r1c4; stte |

I had a real tough time with this one immp! If r2c2=9, I finally found a brutally long chain that lead to 2 6's in box 5 and then if r4c8=8, I found a much shorter chain that lead to 2 9's in column 6 which solved it! Thanks! |
