This is the most engaging way to expand your memory! I have not skipped a day, and I’m always looking forward to my play time right before going to bed.

Hate the noise

Memory challenges are fun however I really dislike the anticipating music played during figuring out which item goes where. it’s very distracting and aggravates my headaches. It’s fun so far.
