I started out playing the games on BrainHQ because I learned from the esteemed Dr. Mike Roizen that, in randomized studies, speed-of-processing games reduce the odds of getting Alzheimer’s by more than 40% after 18 hours of practice over 10 years (less than 2 hours/year). I didn’t enjoy the games of BrainHQ but made myself do them because the benefit could be so huge. Later, I told my cousin what I’d learned about speed-of-processing games because Alzheimer’s runs in our family. She told me she’d been been doing the games on Lumosity, so I gave them a try, and I’ve been hooked ever since. I started out doing the free daily exercises but very soon paid the $15 monthly fee so I could do all the exercises I want every day, and I like them so much that now I practice them all day long, even though 2 hours a year is all that’s needed. The animation on all the games is colorful and entertaining. Some games are just beautiful, others very funny or cute, and the sound effects are out of this world. I really like almost all the games. A few seem impossibly hard and a couple, way too easy, but most have a level that feels appropriately challenging, and all of them let you advance to higher and higher levels. There are a few, like Pet Detective (one of my favorites as far as the sound effects) that I find maddeningly difficult but, unlike most of them, don’t show you afterward what the correct answer would’ve been. It drives me nuts! Another game, Skyrise, kind of insults you by comparing your correct answers to the height or depth of famous landmarks, like Kilimanjaro or the Grand Canyon, which is absurdly irrelevant. Things like that make me feel babied, but, overall, playing the games is a great experience. It reduces my anxiety and improves my mood, even when I’m not thinking about the likely benefit to my brain. Highly recommended.
