  • Heightened Focus – Puzzles requiring sustained concentration build your attention stamina. Brain training has been found to double focus span in 6 weeks [2].
  • Faster Processing Speed – Games that tax processing speed and reaction time hone these skills. After training, seniors were 150% faster on cognitive tests [3].
  • Improved Reasoning – Brain teasers force you to think logically and flexibly to find solutions. Logic game training has improved inductive reasoning ability by over 30% [4].
  • Elevated Mood – Cognitive challenges release dopamine, boosting motivation and mood. Brain training has been shown to reduce anxiety and depression [5].
  • Delayed Cognitive Decline – Keeping your brain active may delay age-related impairment. Training could "turn back the clock" on decline by up to 10 years [6].

With consistent practice, science-backed brain training apps can enhance your cognitive abilities and keep your mind sharp as you age.

How to Evaluate the Best Brain Game Apps

Tips to Maximize Brain Game Benefits

To get the most cognitive benefit from brain training apps, keep these tips in mind:

  • Train consistently – Playing brain games just once a week provides little benefit. Daily training for 5-10 minutes consistently has been shown optimal for improving cognitive abilities over time.
  • Vary games frequently – Switching up game types keeps your brain adapting. Avoid just repeating favorite games.
  • Track progress – Monitoring your performance on game metrics makes progress tangible, motivating you to keep improving.
  • Stay hydrated – Being even mildly dehydrated can negatively impact cognitive performance. Drink plenty of water while training.
  • Address weaknesses – Use apps with assessments to identify weak cognitive areas, then target training to build these skills.
  • Rest and recharge – While brain games are beneficial, be sure to take breaks to recharge. 10-15 minutes of training at a time is sufficient.

The Science Behind Brain Games

There is healthy skepticism around whether brain games can truly make you smarter or improve real-world performance. Much of the early research on brain training had methodological flaws.

However, more recent high-quality studies have provided concrete evidence that consistent training on games targeting specific cognitive skills can yield measurable improvements in those domains.

For example, multiple studies have verified working memory, focus, processing speed, and problem-solving ability can all be enhanced through science-backed brain training programs [7]. The key is training consistently over an extended period on games targeting particular mental capacities.

On its own, brain training is not a magic bullet for dramatically boosting intelligence. But combined with healthy lifestyle habits, brain games provide an engaging way to exercise your cognitive faculties and keep your mind sharp as you age.
