Exercise Your Brain

Not only are PuzzleQuests fun, they’re also good for your brain! Scientific research has shown that solving puzzles improves overall brain function. Mental stimulation is just as important to the mind as physical exercise is to the body. In fact, there are several specific brain benefits associated with solving puzzles.

Improved Memory
Puzzles strengthen the connections between brain cells. They create new connections for improved thinking and mental speed. Puzzles are beneficial for all ages.

Heightened Creativity
A good puzzle causes participants to think about things in new ways. Even if an idea is not the solution to a puzzle, all out-of-the-box thinking helps train the mind to work in new ways.

Whole Brain Development
Puzzles require both logic and creativity. As different regions of the brain work together to achieve the best results, the brain trains itself to integrate different types of thinking for long-term benefits.

Dopamine Production
Puzzles are known for their power to help the brain produce the neurotransmitter dopamine. Benefits include a positive mood, increased concentration, and improved motor skills.
