This is the "worst" I have seen generated, yet SE doesn't mind it much.
It is great ALS practice, I don't understand this as yet.
Sorry, if this seems too easy.

Zoltag,
Fun puzzle. Here is a 'one-step solution'. After the easy stuff,
Code: Select all
*--------------------------------------------------------------------*
| 247- 479- 1 | 6 8 5 | 3 29 47 |
| 23478 34789- 237 | 49 249 1 | 2479- 6 5 |
| 5 469 26 | 3 249 7 | 249 1 8 |
|----------------------+----------------------+----------------------|
| 6 1 4 | 59 59 3 | 8 7 2 |
| 9 37 5 | 8 47 2 | 6 34 1 |
| 37 2 8 | 47 1 6 | 5 34 9 |
|----------------------+----------------------+----------------------|
| 1 467 67 | 2 567 8 | 479 59 3 |
| 23478 5 2367 | 1 67 9 | 247 28 467 |
| 278 678- 9 | 57 3 4 | 1 258 67 |
*--------------------------------------------------------------------*
a (big) Medusa trap shows that r1c12<>7, r2c27<>9 and r9c2<>7 (though r1c12<>7 is enough to solve the puzzle). For a hint on where to start looking, try r1c8 and color away.
