Nintendo 3DS combines all the functionality of 3DS XL at an even more affordable price. Play 3DS and DS games, take 3D photos, and connect with friends with StreetPass and SpotPass. Nintendo 3DS includes two screens. The bottom touch screen makes use of a telescoping stylus that is stored in the unit itself. The top screen displays 3D visuals to the naked eye. Looking at the screen is like peering through a window into a world where characters and objects have true depth. The system also has a 3D Depth Slider that lets players select the level of 3D they enjoy the most. The 3D effect can be ratcheted up to the highest level, scaled back to a more moderate setting or even turned off completely, depending on the preference of the user.
