Yes. There is better than anecdotal, though not rock solid conclusive, evidence that it works. https://en.wikipedia.org/wiki/Tetris_effect#Applications_in_...

I've seen a paper or two supporting the claim, but I remember that I didn't put much faith in them at the time. Seems plausible enough though, and probably wouldn't hurt anyone so until there's a ton of of high quality evidence for it'd still be worth a shot.

Anecdotally, it worked for me, but I'm not really in the mood to look up the literature right now.
