Hi Sebinator0815. It appears that you've made some mistakes along the way. You have six false numbers on your grid. The correct pencilmarks after basic techniques:

Code: Select all

.---------------.--------------.---------------.
| 6    7    4   | 39  138  189 | 5   138   2   |
| 189  189  5   | 2   36   4   | 19  367   37  |
| 129  129  3   | 5   168  7   | 4   1689  189 |
:---------------+--------------+---------------:
| 5    6    189 | 39  2    189 | 7   139   4   |
| 179  3    179 | 6   4    5   | 8   2     19  |
| 189  4    2   | 7   138  189 | 6   5     139 |
:---------------+--------------+---------------:
| 3    19   6   | 4   5    2   | 19  78    78  |
| 278  28   78  | 1   9    6   | 3   4     5   |
| 4    5    19  | 8   7    3   | 2   19    6   |
'---------------'--------------'---------------'


For the rest you need a bit more advanced techniques. Are you familiar with things like Empty Rectangles, X-Wings, XY-Wings, Remote Pairs? If not, this might be a bit tough puzzle for you. We can help, though, but first you need to correct your mistakes.

I'm not sure if this is helpful but this is a printable Empty 9x9 sudoku sheet with the pencilmarks in faint shading in the background of each cell. This may help in reducing these mistakes
