One of The BEST !!!

This is one of the best games ever invented. Most people don't realize the activity that this game utilizes stimulates your brain with audio and visual memory patterns. Keeping the parts of the brain that handle those functions active will help everyday brain function as well as help prevent early dementia in some people. This is a great example of a game that really exercises your brain. I love it ! Sometimes I mute the volume to try to do it without the benefit of the notes.

It's the traditional game of Simon, but a great version of it. So long as you're not looking for something else, there shouldn't be a problem. If what you're looking for is a well-designed and enjoyable version of Simon, you've found it.

I haven't played this game in forever. This is such an awesome colorful version. Love that the center of the buttons are faded out because it makes it so much easier to see which one lit up when in bright surroundings.
