I am really stumped on this puzzle. Can anyone give me a hint about what to try next?
* * 5 | * 6 * | * * 3
8 * * | * * * | * 6 1
* * * | * 4 8 | * * 5
* 7 * | 6 * * | 9 1 *
* * * | * * * | * * *
* 9 2 | * * 3 | * 5 *
7 * * | 4 3 * | * * *
2 4 * | * * * | * * 8
1 * * | 8 7 * | 6 * *
I have not gotten very far on this puzzle at all, and I just don't see what to try next. Any help gratefully appreciated!
Thanks!
