Christmas Memory 2
I must be getting old because memory games were never this hard when I was young, but back then the pieces didn't move around either, which is just mean. I played the easy version of Christmas Memory 2 and found it a nice challenge. To play, click on any two cards to reveal them and find the matching pairs. But be forewarned, after each try the cards move. Sometimes two trade places, sometimes the whole board shifts! If you get three or more matches in a row, you get a bonus.
