On Tour's most unique aspect is how it is played. Rather than a plastic guitar, the game comes with a four-button "guitar grip" that plugs into the Game Boy Advance slot. The game works on both the DS Lite and the original DS as well, with the help of an included small plastic adapter. If you're right-handed (there is a lefty flip mode), you'll slide your left hand through the adjustable wrist strap, cradling the DS in your palm like an open book. Notes scroll downward on the left screen and you push down on the corresponding fret buttons with your fingertips. There's no physical strum bar; instead you use the included guitar pick-like stylus to strum across the guitar that is displayed on the right screen. It takes a little bit of practice to get the strumming motion down, and even when you do, the game doesn't always register your input. This can be frustrating when you're trying to improve your high scores, but it isn't an issue that renders the game unplayable.
