When we think about playing games, learning a new skill doesn’t always spring to mind.

Yet, if the lockdown has taught us one thing, it was to make the most of what we have. It presented a golden opportunity where we got enough time to keep our minds razor-sharp.

And quizzes, puzzles, and other online games can help our brains “workout” and make it sharp. Yes, just bodily workouts are not enough; your brain must exercise too to improve its efficiency.

Although restrictions have now eased, there’s no reason why we should stop playing online games to hone our brains. They’re entertaining, can be played by any age group, and, best of all, they’re usually free.

That said, let’s talk about some of the best online brain games to help you improve your brain’s capacity, memory, focus, and enjoy its long-term benefits in your life.

But first,

Why Online Games?

There are plenty of positives to online gaming. Most notably, they often present an opportunity to increase personal wellness and productivity and can be played wherever you are and whenever you want. Not to mention, they lift our mood and help us unwind, no matter what’s our age.

Also, just like physical exercises keep our bodies strong, brain games, including online ones, can potentially sharpen our memories and keep our brains healthy and active. This is especially true for games involving critical thinking and problem-solving.

So, let’s explore the top 10 online games to hone your mental power.

Nintendo Brain Age

This is a puzzle video game inspired by the research of a notable Japanese neuroscientist Dr. Kawashima. His studies assessed the impact of performing some mathematical exercises and reading on brain stimulation. The game was devised to energize and improve memory and concentration skills.

The advantage of Nintendo Brain Age is that you can choose the games to play, so there’s tons of variety here. Nintendo suggests playing one or more of the eight main kinds of games for around five minutes a day for the best results.

However, to ensure you don’t over-train your brain in just one area, you’re only permitted to play each of the below once a day; that way, your brain gets an all-over workout! The eight games are:

  • Devilish Blocks
  • Devilish Calculations
  • Devilish Cups
  • Devilish Listening
  • Devilish Mice
  • Devilish Pairs
  • Devilish Reading
  • Devilish Shapes

Now, suppose you want to rest your brain after playing any of the above games. In that case, the game also includes a relaxation mode where you can match colors and music. You can also interact and compete with other players.


This review wouldn’t be complete without referencing a few of the classics, of which Sudoku is one of the undisputed kings. It’s an excellent brain teaser to help improve focus, concentration, and logic skills.

For beginners, Sudoku is a logic-based game, where you place numbers from 1-9 only once in each box, line, or column inside a 9×9 grid.

There are tons of options here. You can either play it via a web browser or from one of the many Sudoku apps found in the Google Play and Apple Store. With this particular Sudoku, you have access to 5,000+ Sudoku brain puzzles across different difficulty levels.

You can also access player tips if you’ve never played it before and are intimidated by the idea of playing a numerical game. However, if playing with numbers is a daunting prospect, imagine the numbers were replaced by letters or symbols. Now, you’ll soon see that it’s not a numbers game; instead, it’s a game that promotes logic and powers of deduction.


Another gem in the world of online gaming is Solitaire. This 52-card game is also sometimes known as “patience” or “cable” and is both a relaxing and stimulating pastime that you can play alone for hours.

Here’s what happens: The pack of cards is shuffled, and cards are distributed face down into seven columns. The first column on the left-hand side has one card, and each subsequent column is dealt with an additional card. This is called a tableau. Next, the last card in each pile is turned over facing up.

Players draw and play the remaining cards from a stockpile and put unused cards in a waste pile. Once all the cards are turned over, the cards that haven’t been moved to the tableau or foundation can be redrawn from the stockpile in the same order.

The objective here is to transfer all the cards from their starting positions to four foundations in running order and suit. You can play over 500 versions of free, online solitaire games, including Spider on Fear not; the website is also mobile-friendly, so you can play while you’re on the go too! provides helpful explanations of the game’s rules and a brief outline of how to play. In addition, they include video clips with tips and strategies to help you play the game more effectively.

Not to mention, you can restart current games, undo actions, do a random card shuffle, and select only winnable games. You can also choose from differing difficulty levels with Turn 1 and Turn 3 card options and test yourself by timing how many moves it takes you to win a game and how long.
