Sudoku and Kakuro puzzles

I learned about sudoku puzzles when I was in middle school and got addicted. For those who do not know what they are, please go to this link for an explanation. I would try to describe it myself, but these is a good chance you and I will both get confused. Therefore, please go to the previously mentioned link, where someone has already comprehensively explained this activity – including a step-by-step example. 

When I first started working on sudokus, I found it was much easier than trying to solve a crossword puzzle since I rarely used the complex words that these games asked for. On the other hand, I loved math and it was quite fun solving a puzzle using arithmetic and logic to eliminate the possible choices for each box.

My algebra teacher, who taught the class about sudokus, would keep a pile of the puzzles on his desk for us to pick up whenever we had free time. I ended up taking a lot of those sheets and was solving them at every chance I had. He saw my interest and introduced me to kakuro puzzles. This game is similar to sudoku, but rather than me trying to explain the differences, here’s another link.

At that time, I was completing sudokus at a decent pace and felt confident about this new challenge. 20 minutes later, I decided that the kakuro he handed me … was difficult. I was never able to complete it. Eventually, the puzzle was lost and I forgot about it. Life went on and my time was filled up with all sorts of things. A few months ago, my schedule changed and I got about 10-15 minutes of free time each morning. Not willing to sit idly, I started to solve online sudoku puzzles. I quickly became stuck between the medium and hard levels. The medium levels were solved quickly, but the hard levels were so complicated, that I simply did not have enough time to work on them. Curious about what else I could do, I searched for similar puzzles and eventually found a site with kakuro puzzles. It took some time, but I actually managed to solve one!

I think the reason for failing so long ago was because kakuros resemble crossword puzzles, which I am not very fond of. Once I got over that displeasure, I started to focus on the problem and was able to eliminate certain numbers and figure out the correct combinations. It was frustrating because it took me a while to mentally calculate the sum of various numbers and subtract from the given number to see how much I was missing. This issue is a result of using a calculator for so many years. Now, that I have worked through a good number of these puzzles, my addition and subtraction skills are actually a lot better.

I’m glad I found these puzzles again and will probably continue to solve them until something new catches my eye or my little bit of free time gets eaten away.
