Every single person in my friend group loves a difficult riddle.

3 Benefits of Playing Mind Games With Your Friends

30 Interesting Riddles for Adults - Challenge Your Brain Now! (31)

Anyone who has yet to play a match of riddles would probably think it's a boring hobby, but the truth is, it's the opposite. It's fun! I like to think of it as some sort of brain gym. If you or a friend needs more convincing, here are some benefits of playing mind games with your friends.

1. It improves your social skills.

These days the only interaction I get with my friends is online, which is why it is a breath of fresh air when I get to meet them to play puzzles or mind games.

One of the obvious benefits of engaging in brain games with your friends is the social stimulation it provides. Aside from providing an opportunity to stay connected with your friends, it also teaches you teamwork and how to build strong relationships. It also encourages you to use your social instinct by forcing you to “read the room” every time you play a match of charades or a one-word exercise.

2. It promotes critical thinking.

Games are purposely designed to challenge your critical thinking abilities. In fact, functional MRI brain scans have found that people who play video games for three or more hours per day showed higher brain activity in regions of the brain associated with attention and memory than those who never play.

Any game that encourages you to practice decision-making and critical thinking benefit your mental health. Games such as chess, 4-in-a-row, backgammon, 2048, and minesweeper encourage players to think strategically with every move to trick and beat their opponent.

3. It provides stress relief.

Playing games is fun, and when you're having fun, you trigger a release of dopamine in your body that helps you feel good and cope with the stresses of everyday life.

There are a lot of studies that prove that playing any type of game, whether it be video games or mind games, can help reduce stress and alleviate symptoms of anxiety, depression, and loneliness.

Level up your brain games and the fun by following these tips to make solving riddles more exciting.

1. Make a bet out of it.

Solving riddles can be fun, but it can also get pretty boring when you're just sitting there, waiting to figure out the right answer. If you and your friends are up for it, how about making it more competitive with a bet?

It could be anything from the winner getting more chances to guess the riddle during the next round to the loser buying your gang a glass of beer the next time you catch up.

2. Time it.

If you and your friends consider yourselves expert "riddlers," why not make your games exciting by timing them? This should be a race against each other, trying to beat each other's personal best time to solve a riddle.

Frequently Asked Questions

Can people of all ages enjoy puzzles?

Yes. Anyone can do it, no matter what your age is. However, it's worth remembering that there are different types of puzzles for a specific age group.

What is a fun way to deliver riddles?

If you're making your own riddle, which is 100% possible, by the way, I recommend taking your time to work it out until it makes you happy. I also suggest testing it on a few people. If they can answer it without breaking a sweat, then your riddle might be too easy. If that's the case, you can always go back to your clues to see how you might make it more challenging.
