Sudoku: the game of life

March 29, 2021

I swear it was Sudoku that held me together mentally and emotionally at a time when I was incredibly fragile. Literally, it saved my sanity. And it continues to be an oasis of tranquility for me, especially when times are tough. But before I get into that, I have to clear up a misconception. I’ve heard people say they’re not interested in Sudoku because they don’t like math. Sudoku is not math. Admittedly, the Japanese word “sudoku” means single number, and the game might resemble math in that it’s logic-based and uses the numerals 1 to 9 in the gameboard grid, but they’re just symbols. The numerals could easily be replaced with nine letters from the alphabet or, say, nine astrological symbols (except they’d be awfully hard to draw in the little grid squares) and the game could be called “Single Symbol”. Similar to chess, Sudoku’s a brain-exercising game in that when you’re “making a move” you have to think a few steps ahead about the implications. Similar to life, it’s a game of successive challenges and when you find your Goldilocks level of Sudoku difficulty, it feels just right.

I get that Sudoku may not feel right for everyone regardless of the difficulty level, just like I generally don’t enjoy crossword puzzles, which appeal to gazillions of people. But whether or not you’re a Sudoku junkie, when you consider the nature of the game, you may come to see it as a tidy little metaphor of life offering some helpful hints on how to play the Big Game.

As Mother Teresa said:

First, I’ll describe how Sudoku is played. Then, I’ll share what says about the traits of people who enjoy playing Sudoku, and finally I’ll offer up my takeaways from the game that are relevant to playing life enjoyably and rewardingly.

How Sudoku is played?

On your computer, tablet, or phone, or in a puzzle book, or in a newspaper if there are still some of those around, you’re presented with a Sudoku grid comprised of nine columns, nine rows, and nine sub-sections. Altogether, there are 81 little squares in the grid, some of the squares contain numerals. The aim of the game is to fill in all the blank squares with the numerals from 1 to 9 with no numeral duplicated in any column, row, or section. Generally, but not always, the more numerals the grid is pre-populated with, the easier the game. That’s it. Some people like to play competitively with others to see who can finish the game fastest. Others like to play alone, competing against the clock. Still others, like me, are solitary players without the clock, deriving satisfaction from meeting a challenge in our own time.

What are the traits of Sudoku devotees?

According to, serious Sudoku players characteristically exhibit the following traits:

  • orderly thinking, a methodical mind
  • ability to focus, focus, focus
  • coolness under pressure
  • determination
  • ready to recognize opportunities
  • ability to switch gears
  • competitive
  • meditative

All of these traits, I think you’ll agree, are likewise useful in the game of life. However, I’m going to elaborate on the meditative trait because this is the one that is most significant for me; plus, at the opening of this article I alluded to the salvific importance of Sudoku as a tool to aid my meditation when I most needed it, and I suggested I’d return to it. says:

Many Sudoku players find that the game gives them a sense of calm. The process of solving Sudoku puzzles tends to be relaxing and even meditative for many people…[some players] use Sudoku as a chance to clear their mind and go into a deep-thinking mental state where they seem to “become one” with the puzzle.

It might sound a little woo-woo, but I get it! Because I’ve been there, done that. I can attest to how playing Sudoku can be relaxing and calming, and foster meditation. Over the years I’ve been immersed in Sudoku games at home, on trains, in airport lounges, pleasantly oblivious to people around me talking and doing whatever they’re doing. In circumstances like that, it’s really about getting nicely into flow, a state where you’re so engrossed in your activity you’re unaware of the passage of time and anything external to your focus. But I’ve gone much deeper than that with Sudoku. I’m referring my experience during a hyper-intense period in my life. It was when I became sole caregiver to my adult daughter while she was experiencing a mental health crisis that manifested in its extreme as bipolar mania and psychosis. Having no experience in the area of mental illness and being on my own, I was totally unprepared and unsupported for this suddenly-imposed, crazy-making life challenge. Normalcy was swept away and replaced with chaos, sleeplessness, unpredictability, fear of the unknown, and intense anxiety. In the maelstrom, to my huge surprise, I found a place of calm and comfort. It was in playing Sudoku. 

At the just-right-level of difficulty, I found that the puzzles demanded all my focused brainpower to solve them. By becoming completely mentally enveloped by the logic task at hand, there was no dangling part of my mind that life stressors could grab hold of; I was temporarily secure from my confused and frightened thinking about my inability to solve the bigger challenges I was facing. That escape into a mentally engrossing but inconsequential task gave me respite, which, in hindsight, I believe was crucial to me not going off the deep end. I went through a lot of puzzles! I found out early on that the restorative escape—the tranquility—didn’t happen if the puzzle was too easy—part of my mind was still free to wander because total focus wasn’t required. And if the puzzle was too hard, frustration prevented me from finding my way into that place of calm. The Goldilocks puzzle took me to where I needed to go, to be one with it.

And the relevance of this to life is…?

What is Sudoku’s relevance to playing life enjoyably and rewardingly?

Over the years of playing Sudoku, I’ve found that the game reminds me how to more happily and fulfillingly play life. Here are reminders that serve me well:

  • Life is unending practice. Each grid of Sudoku I complete is practice for the next grid. Each challenge I face in life is practice for the next one; a challenge is an opportunity for learning and growth to be appreciated, not regretted.
  • Life is collecting ahas. It doesn’t happen in every Sudoku game, but the excitement of an “aha!”—discovering a new way to solve the puzzle—is visceral. When I find a solution to a Sudoku situation that persistently stumped me, frustrated me, kept me stuck, I feel empowered knowing that that particular situation can no longer stop me. And in the game of life, each “aha”, each nugget of awareness and understanding that I collect, increases my ability to overcome self-sabotaging beliefs, thoughts and behaviours that have been keeping me stuck.
  • Life is playing at the Goldilocks level of difficulty. And that level is not static. In the beginning, I played Sudoku at the easy level. That’s where I needed to be, as I picked up tricks and rules, and discovered patterns. For a time, the easy level was motivationally challenging. Then it wasn’t. With ongoing practice and collecting of ahas, over the years my just-right-level of challenge moved from easy to medium to hard to challenger to expert. And here I sit, enjoyably and rewardingly challenged, knowing I’m going to continue to be stymied by a good number of puzzles until I collect more ahas. Some of the expert-level games I play remain unsolved for days or weeks until I’m able to see what I’ve been missing all along. And so it is with life. When I’m consistently playing below my Goldilocks level—when I’m underchallenged at work, I’ve no stimulating interests, I’m not engaged in appropriately intense physical or mental workouts—then I’m feeling unmotivated, bored and unfulfilled. When I’m regularly playing above my Goldilocks level—when work demands are excessive, I’m pursuing too many or too stressful interests, I’m pushing myself too hard mentally and physically—then I’m feeling unmotivated, overwhelmed and ill. At the Goldilocks level, with just the right amount of stress or challenge, life is motivating, enjoyable and rewarding. 
  • Life is playing alone, one with the game. Even if I were a competitive Sudoku player online or face-to-face in competitions, I’d always still be playing the grid in front of me by myself. It’s a solitary game, just me and the grid. There may be similarities in the logic or steps that I use to solve the puzzle compared to the process another player of the same puzzle might follow, but, in the end, I’ll do it my unique way. There are how-to videos on Sudoku-solving and I’ve integrated helpful expertise from others into my experiential learning, but still my game is singular, because I am singular. And at its best, it captivates me wholly, so that I’m fully and completely immersed in it. Sudoku reminds me that I’m playing my game of life alone – practicing, making mistakes, learning as I go, incorporating the wisdom of others, enjoyably and rewardingly playing at my evolving Goldilocks level. At it’s best, in those moments of flow when I’m one with the game of life, it is an oasis of tranquility. 





Hi, I’m Annie Gyg. I’m drawn to write because one of the things that I find most fulfilling is sharing my life experiences and thoughts in the hope that some little snippit from my bountiful collection of mess ups and peculiar thought processing may actually help someone somewhere actualize their real, unencumbered self—as so many writers have done for me. You—authentic and unfettered—are best positioned to make a positive difference in a world desperately begging for change.
