thank you all for sharing solutions!
my own was like so, simalar to marek:
- Code: Select all
12 89
+-------+-------+-------+
| . 1 . | . 7 . | . 8 . |
| . . 2 | . . . | 9 . . |
| . . . | 4 . 1 | . . . |
+-------+-------+-------+
| 7 - - | # 5 # | - - 3 | 1289
| - 8 . | . . . | . 2 - |
| - . 9 | . . . | 1 . - |
+-------+-------+-------+
| 6 . . | 2 . 8 | . . 4 |
| 3 . . | . 9 . | . . 7 |
| # . . | . . . | . . # |

8 digits, at most one each in b46, the remaining 4 go in the #ed cells
=> -46r4c46, -4589r9c1, -1256r9c9
to finish i did the same as everyone else, but here's something different to the x-wing & triple:
- Code: Select all
,---------------,----------------,----------------,
| 45 1 3456 | 9 7 2 | 3456 8 56 |
| 8 47 2 | 356 36 356 | 9 47 1 |
| 9 36 3567 | 4 8 1 | 3567 3567 2 |
:---------------+----------------+----------------:
| 7 2 #6-4 | 1 5 9 | 8 #4-6 3 |
| 1 8 3456 | 367 346 3467 | 4567 2 9 |
|#45 36 9 | 8 2 3467 | 1 4567 #56 |
:---------------+----------------+----------------:
| 6 579 17 | 2 13 8 | 35 359 4 |
| 3 45 8 | 56 9 456 | 2 1 7 |
| 2 459 14 | 357 134 3457 | 356 3569 8 |

one orientation of the 46 pair in r4 places two 5s in r6
(or just a y-wing, if thats too fancy
)
