Do brain games actually work? What the research says
Last reviewed April 25, 2026
Quick Answer
Research shows brain games improve performance on trained tasks, but evidence for broader cognitive transfer is mixed. The 2016 Simons consensus found limited far-transfer effects.
Detailed Answer
The question of whether brain games actually improve cognitive function is one of the most debated topics in cognitive science. The landmark ACTIVE study (2006, 10-year follow-up 2014) trained 2,832 older adults and found processing speed training reduced dementia risk by 29% over 10 years. In 2008, Jaeggi suggested working memory training could improve fluid intelligence, sparking a brain training boom. The most comprehensive review came in 2016 when Simons and 70 leading cognitive scientists concluded brain games reliably improve trained tasks, sometimes show near-transfer, but minimal far-transfer. Recent 2022-2024 research using adaptive protocols has been more encouraging. The practical takeaway: treat brain games as skill practice rather than a cognitive cure-all. Sudoku improves number reasoning. Memory games improve working memory. The key is variety — training diverse skills has more cognitive benefit than practicing a single task exclusively. Combine with physical exercise, quality sleep, and social engagement for best results.
