How to play ?
Sudoku is played on a grid of 9 x 9 spaces. Within the rows and columns are 9 “squares” (made up of 3 x 3 spaces). Each row, column and square (9 spaces each) needs to be filled out with the numbers 1-9, without repeating any numbers within the row, column or square.
Does it sound complicated ? As you can see from the image (in the video) of an actual Sudoku grid, each Sudoku grid comes with a few spaces already filled in; the more spaces filled in, the easier the game – the more difficult Sudoku puzzles have very few spaces that are already filled in.
Benefits of Sudoku
New research, had concluded that doing a Sudoku puzzle every day could lower our brain age by a decade. According to a study, published in the International Journal of Geriatric Psychiatry, over 50s improve their brain function more as they complete the word games.
19,100 people participated in the research, and were tested on their attention, memory, and reasoning, as well as being asked how often they completed Sudoku. Findings showed that those who did more of them performed better in tests, and had a lower 'brain age' than those who didn't. The 'age' difference in brain function was ten years for those who did the puzzles regularly, while for short-term memory it was an eight-year difference.
