Leveling Up: Study Finds Video Games May Boost Kids’ IQ

Turns out screen time isn't all created equal.

At Kidoz, we’ve long believed in the power of digital play - and now, the science is catching up. A recent peer-reviewed study from Sweden has found that playing video games may actually increase children's IQ over time.

The Study in Focus:

Researchers tracked 9,000+ U.S. children aged 9–10 over a two-year period. Their goal? To explore how different types of screen time (TV, social media, and video games) impact cognitive development.

The Surprise Finding:

Children who spent more time playing video games saw an average IQ increase of 2.5 points, even after controlling for socioeconomic background and genetics. This suggests that interactive, goal-oriented screen time may support cognitive growth, unlike passive screen time like watching TV or scrolling social media.

Why This Matters:

This study reinforces what many parents and educators have started to observe:
Not all screen time is created equal.
Games can improve skills like memory, logic, attention, and spatial reasoning: especially when gameplay is rich in problem-solving and decision-making.

"This study reinforces what we've seen in the world of kids' digital engagement: interactive play, especially in games, can be a powerful tool for cognitive development. In my over 30 years making games, I have witnessed first hand the positive impact playing interactive games can have.  At Kidoz, we're proud to help shape experiences that are not only fun and safe but also support growth and learning in meaningful ways."

A New Perspective on Screen Time

This research adds to a growing body of evidence that challenges the idea that all screen time is harmful. While balance is still important, interactive and engaging digital experiences like gaming can support cognitive development, especially when they encourage kids to think critically, solve problems, and stay focused.

As families, educators, and researchers continue to explore how kids interact with technology, it’s clear that gaming can play a positive role in learning and growth.
