What these games train (in plain words)
Each game puts light stress on one or two cognitive skills: working memory (holding bits in mind), attention (staying on task), processing speed (fast, accurate clicks), and reasoning (finding patterns). Short, varied sessions help you stay engaged without burnout.
- Working memory: n‑back, Simon, word recall
- Attention and inhibition: Stroop, go/no-go
- Processing speed: reaction time, symbol search
- Reasoning & math: sudoku, kenken, kakuro
- Spatial: tangram, rotations, nonogram/picross
Note: brain games are entertainment and practice, not medical treatment or a promise to boost IQ by X%.
