Related to this Q&A. I am looking for a pattern that could be applied in order to solve this Sudoku.
The current patterns that I apply:
- Ensure that every digit appears once in every block
- Ensure that there is a unique sequence from 1 to 9.
Now I am blocked as the block top right could contain a 8 and a 5, but I cannot rationalize where the 8 and where the 5 should be placed. What pattern am I missing?
As encouraged by @legorhin I tried to come up with possible solutions for the Sudoku cells.
