Found this fun little game that tests how good your short-term memory is. You’re show a list of items, and then when you think you have them memorized, you click next and pick them from the items shown. It starts off easy and then they add more items. One wrong move and you’re out! My first try got me to memorizing 15 items at a go, but I understand that between 4 and 9 and average. Your first try scores in the comments, please!
