Brain games don’t make you smarter. Let’s get real.

The myth claims brain training apps make you smarter overall. Nope. Truth is, beating Sudoku levels just makes you better at Sudoku.

Why do people believe it? Because companies make millions selling quick fixes. And yeah, feeling sharper after playing is real—but that’s placebo, not IQ gains. (1/3)

Here’s what science says:
Cambridge studied 11,000 people. Brain games didn’t improve overall smarts.
Your brain isn’t like a muscle. Doing repeat puzzles doesn’t build intelligence. Learning actual skills does.

Better ideas:
Sleep well. Your brain cleans house during deep sleep.
Learn something hard—like guitar or Brazilian jiu-jitsu. Complex skills rewire your brain.
Cardio beats puzzles for growing BDNF (your brain’s fertilizer). A sweaty run does more than a chess app. (2/3)
