I'm stuck on a puzzle with difficulty level normal. Hope someone can give me a clue on how to solve this problem.
This is how it looked from the start.
|x 6 x||x 9 x||5 x x|
|x 3 x||2 x 4||x x 9|
|x x x||x x x||x 7 2|
|x x 7||9 6 2||x x x|
|x x x||x x x||x x x|
|x x x||1 3 7||4 x x|
|4 2 x||x x x||x x x|
|6 x x||8 x 5||x 9 x|
|x x 8||x 7 x||x 3 x|
And this is how far I got before I got stuck.
|x 6 x||7 9 x||5 4 x|
|7 3 x||2 x 4||x x 9|
|x x 4||x x x||x 7 2|
|x 4 7||9 6 2||x x x|
|3 x x||5 4 8||9 x 7|
|x x x||1 3 7||4 x x|
|4 2 x||x x x||7 x x|
|6 7 3||8 2 5||1 9 4|
|x x 8||4 7 x||2 3 x|
Appreciate all help.
