Do brain games really work? An honest look

It's a fair question, and the honest answer has two halves. No, brain games won't magically raise your IQ or hold off every effect of aging — claims like that have rightly been criticised. Yes, they can be genuinely useful when you're clear about what you're getting.

The overclaim trap

The cleanest finding in the research is also the least exciting: you get good at what you practice. Practice a task and you improve at that task; the improvement transfers to very similar tasks, and fades the further you get from them. Beware anyone promising more.

What you actually get

Treat brain games like a gym, not a magic pill. The value is in showing up, not in any single session.

How to get real value

Play short and often rather than long and rarely. Use adaptive difficulty so you're always a little challenged. And don't expect a game to fix your focus on its own — pair it with sleep, movement and a tidier environment. That's the boring stuff that actually moves the needle, and a daily game is a pleasant way to anchor it.

That's the philosophy behind Cognito: useful, honest, free — a good daily habit, not a miracle cure.
