I've run out of (obvious) single-stepper puzzles. Let me know if the latest crop of puzzles prove unsatisfactory.
Code: | +-----------------------+
| 6 . . | 1 . 9 | . . 2 |
| . 4 2 | 8 . . | . . 9 |
| . 9 . | . 7 2 | . . . |
|-------+-------+-------|
| 8 1 . | 5 . 7 | . . . |
| . . 5 | . . 1 | . . 4 |
| 2 . 6 | 9 8 4 | 1 . 3 |
|-------+-------+-------|
| . . . | . . 8 | 4 . . |
| . . . | . . . | . 2 . |
| 4 2 . | . 9 6 | . . 5 |

As usual, a very interesting puzzle. I like the puzzles that require multiple steps; makes the fun last longer......

ERs (3,1)
W-Wing (17)
BUG+1
I like multiple steps too. When I'm looking to spend 45 minutes and I'm done in 20, that makes me go through more puzzles. Regardless of number of steps, if I can finish a puzzle with legitimate steps, i.e., steps that I don't consider trial and error, then I'm happy.
Of course, that has its limits; I'm not that thrilled when I take eight steps while everyone else finished it in two. |
