Describe a puzzle you have played

Solving puzzles is considered to be one of the best loved pastime activities. I play and solve various kinds of puzzles. The most sophisticated one was Sudoku. It is a logic-based, combinatorial number-placement puzzle. I found that game in my tablet and wanted to give it a try. The one I solved had 16 rows and 16 columns. That's why it was very difficult and I spent half of my day on it. Well, doing Sudoku demands a razor-sharp mind and strong logical thinking abilities. At first glance, it seemed as easy as pie, but when I started doing it, I recognized that it is not just sequence of numbers but something analytical. Having done that annoying puzzle, I promised myself to not to do it again as it is not really my thing. I felt exhausted and anxious because it was arduous task I have ever done.
