I’ve certainly seen from playing Wordle every day that your game improves over time. The brain is like a muscle (not in how it functions) in that practice and time spent sharpening it, does show improvement. It’s like any hobby you do too – practice makes better (or perfect if you really dedicate regular time).
There are many apps out there that purport to beef up your memory skills, though research on whether they work has been spotty and conclusions about efficacy are pretty limited. One thing we do know is that they’re not going to magically cure major cognitive decline. Still, if a few puzzles a day help you feel better and get your gears going, it could be worth a download just to get that rush. Apps are just one of many ways to get a little brain boost, but below are some of the better ones out there.
I’ve tried Lumosity and Cognifit so far. Lumosity is quite nice in that it benchmarks you against others of your age profile. Cognifit was a bit more difficult and the finesse you can use your mouse with, does also make a difference. Most are time based, so you also want to make sure you are in a space where you won’t be disturbed at all. Any phone alert etc is going to pull your concentration away.
