I started playing sudoku Sudoku with my brother Mark over a decade ago.
Sudoku as a Japanese numbers game in which a square grid has to be filled with the numbers 1 to 9.
Every row and column has to be filled in without repeating, the digits.
It looks similar to a crossword.
Puzzle there are varying degrees of difficulty in Sudoku.
The fewer starting Clues clues provided the harder.
The puzzle is, I found it.
Tricky to wrap my mind around the game at first, but I improved rapidly when I took it.
Seriously, the first few days I played.
It took me at least ten minutes to finish intermediate levels.
While Advanced advanced versions took at least half an hour, sometimes I just gave up or completed a grid, but with the wrong Solutions, my younger brother.
On the other hand, always finished a few minutes faster.
I started with the easier puzzles and but and progress was fast, so it was fun.
Initially, the problem came when I tried the dog.
Amps levels.
It was so hard to solve with very few Clues clues.
And I had to use a lot of trial-and-error.
My pencil was worn down to a nub erasing and rewriting my answers wrong.
I got even more frustrated when Mark and I competed to see who can solve the puzzles faster and , and I never won.
He was always a few steps ahead of me.
