Brain games

Brain training games are games that allow players to complete tasks that practice specific cognitive skills that exercise their memory, attention span, logic, and fast thinking. Brain training activities can range from puzzles, video games, and board games, and they all come in varying degrees of difficulty. Despite being fun to play, each of these games has some added benefits for your brain, too—from helping to develop your problem-solving and reasoning skills to improving your eye for detail and abstract thinking abilities.

Research shows that brain training games have been proven to make a “major impact on cognitive function.” As you play brain games that involve critical thinking, logic, and creativity, your brain is adapting and rewiring itself to improve its performance. Or, if you play a game that tests your ability to remember visual patterns, it can enhance your brain’s ability to spot patterns. Likewise, memory-boosting games can help with recall and word or number puzzles can compel your brain to uncover hidden solutions—all of which, over time, can help improve cognitive functions and keep your brain “young.”

There are endless free brain games on the internet that you can play to give your brain a workout. Want to experience that feel-good moment when you finally figure out the missing piece to a tricky brain puzzle or when you finally crack a tough riddle? Just check out our giant collection of the best brain training games, puzzles, and problems below for some awesome brain activities that you can do either by yourself or with a group of friends.

Brain teasers

To put it simply, a brain teaser is a type of puzzle or brain game, often involving lateral thinking. That means to solve it, you’ll have to use a creative, less straightforward thought process and the solution won’t be right in front of you. There are varying difficulty levels for brain teasers, but their main objective is to make you think more critically. Solving these games boosts brain power, keeps your memory strong, and keeps everyone entertained. Once you’re done with these, take a stab at solving these free printable brain teasers.

Can you spot the difference?

You’ve probably played a “spot the difference” game before, where you compare two nearly identical images and look for subtle differences between the two. The instructions will tell you how many differences you need to spot and circle—which, according to studies, activates your right posterior parietal cortex. This part of the brain is responsible for how a person directs their attention, their spatial perception, and their visuomotor control.
