I had a similar experience with a free memory test online. At first, I treated it as a fun challenge to compare scores with friends, but after practicing for a couple of weeks, I noticed improvements in focus and short-term memory in daily tasks, like remembering codes or phone numbers without checking notes. Using the free memory test online regularly allowed me to track my progress, test different memorization strategies like visual grouping, and see small, consistent improvements. The competitive aspect keeps it interesting, but the real benefit seems to be the repeated mental exercise, which makes recalling information in real life easier and faster.
