By introducing this system, you can draw lines on the screen with two to four people. When you face a puzzle you can't solve yourself, or you're playing it with other people surrounding you, they can say, "oh maybe you should go here, or maybe you should take a look over here" - they can participate in it as well. You can also use this for perhaps a puzzle you have already solved yourself. If you want to give that to someone else and you want them to solve it, you can give them hints as they go along. This is another thing we wanted to just use the remote to do this.
