## Puzzle power

Working on puzzles has huge benefits for brain health, says The Healthy, especially as we age. An afternoon jigsaw puzzle or crossword keeps the brain in good shape and keeps stress at bay. Puzzles and brainteasers help develop critical thinking skills because they bolster memory, strengthen intelligence, and refine your methods of analysis—getting you thinking with a focus on details, dissection, and problem-solving. Puzzles are great for kids, too, as brainteasers cultivate thinking skills. Scroll on to test your skills with some challenges, followed by their solutions. Or, if you’re in the mood for a more *visual* exercise, check out these 25 optical illusions that will blow your mind.

## Maze: Challenge

Maze puzzles purposely disorient you, and that is their power. Experiencing a sense of befuddlement presents a great challenge for your brain and makes your inner logician kick in to find a way to help you out. Illustrated mazes on paper are much easier to solve than the life-size mazes they’re named after. Malia Wollen at *The New York Times* explains that “Humans have been building mazes and labyrinths for millenniums; they arose independently in ancient cultures around the world.” Mazes provide a fun challenge that allows you to flex your innate sense of direction.

Take the challenge above: Start at the red arrow, then carefully chart your way through. When you’re finished, scroll on to learn if the path you took is the right one. Need a break first? Marvel at 9 of the world’s most incredible mazes.

## Maze: Solution

Take the longer path to start, pass the first intersection, then zig and zag your way through from there.

They reflect the inverse along the set plane. Too easy? Here are puzzles that less than 60 percent of people can solve.

## Mirror image: Solution

The answer is #3.

## Twin set: Challenge

Your brain gets a workout when you twist it into new perspectives and positions. At first glance, these color block shapes look identical. However, to notice which option is identical with the first image, you have to find ways to distinguish differences. Scan the shapes and once you find a noticeable difference you can discard that option and move on to the next. Once you find the answer, scan again to make sure you’ve got it exactly right. Can you solve these tricky shadow puzzles?

## Twin set: Solution

The answer is #4.

## Piece it together: Challenge

This is another visual brain-twister that asks you to mentally pick up the pieces to find the one that fits in the cube. This puzzle works with your visual and spatial intelligence.

## Match game: Challenge

You develop critical thinking skills when you work on brainteaser puzzles like this one. Analysis isn’t always second nature; it’s a mode you move into by thinking in new ways about familiar problems. Looking at two squares, it’s hard to imagine how you’d manipulate the current shapes to make ten squares. Use spatial reasoning to use the matches from one square to create more. Don’t forget that while you’ll make smaller squares, you can also count the larger square that contains them all. For a tricky word test, see if you can figure out if these funny-sounding words are real or made up.

## Match game: Solution

Move four matches from the lower square into the upper square and you’ll have squares within squares.

## Bright idea: Challenge

This brainteaser asks you to look closely at the details. First, look for the pattern in sequence by examining the fringe pieces of the lantern. You can eliminate options by looking for the sequence.
