Binary logic puzzles engage logical reasoning, pattern recognition, and working memory simultaneously. Constraint satisfaction tasks effectively activate executive functions in the prefrontal cortex.

  • Constraint satisfaction and prefrontal executive function (Goel & Grafman, 2000)
  • Binary logic and working memory training (Jaeggi et al., 2008)
