That’s Right – playing Sudoku can boost cognitive skills. Not only that, but you can also improve your working memory and reasoning skills. This is great news for senior citizens like me (I hate to admit that!), and it provides hope for the future – as long as you actually exercise your brain with Sudoku.

Improve Cognitive Skills by Playing Sudoku

Sudoku is a LOGIC GAME. Categorizing Sudoku as a math game is a common misconception, one that I made myself before I was fully aware of this. So, as a logic game, it is only reasonable that you can improve your logical reasoning skills by simply playing on a regular basis. I can tell you that, by personal experience, you can expect to find that you will be able to solve Sudoku puzzles faster and faster due to understanding the logic of why each cell is solved given the situation. It is a very satisfying experience, and one that I hope that you too will have this simple pleasure.

There are many cognitive activities for seniors and adults, but Sudoku, in my humble opinion, is one of the top cognitive help for seniors – like me LOL!

I have added a list of citations below of scientific studies which give evidence that playing Sudoku will improve cognitive skills, including a synopsis of each.

Cognitive Activity Books for Adults

So, I was aware of Sudoku for many years, but it was not until I grew older (into my 60s!) that I became aware of the importance of mental exercise. So I Googled cognitive activity books for adults and found that a high percentage of the output was Sudoku books! Hmmm – I never played Sudoku before then, but I found a lot of literature that suggested that Sudoku was one of the best cognitive activities for adults. That is when I began my Sudoku journey…

…and found that playing the game was not as easy as I thought! Luckily, I found some great videos on Youtube (I especially enjoy Sudoku Guy), and I quickly began to solve the puzzles faster and faster – but just the easy ones – LOL! Over time, I was able to solve harder puzzles after gaining some experience. And you can too!

When I began to write my Sudoku books, I decided to create books in series; that is, separate difficulty level books in each series. After seeing that my books were actually selling, I decided that I would make the easy level books available as free PDF files. This way, I can have the satisfaction of helping others and also hoping that the people that download the PDF books will also decide to purchase my higher-level books 😉

So, if you are ready to improve cognitive abilities using Sudoku, take a look at the downloads available Here on my homepage. I sincerely hope that you will enjoy them and hope that your mental clarity will surge dramatically!
