This Portable Pocket Simon is exactly want you need to build, reinforce or improve your mental recollection skills. Portable means you can take it anywhere. Batteries Included. I have loved Simon since I was a kid. I got this toy from my dad a few years ago, and love it! It is fun to play with friends, and it has several game options. You can even see the last run. It has different difficulty settings for the Simon master, which makes it even more versatile! I recommend this toy for a stocking stuff-er, party favor, or small gift to any Simon-lover!
