how to turn music off in puzzle game on my iPod shuffle?

Hi, friends in my IPod shuffle I have puzzle game and I love to play this puzzle game but the problem is that I don’t want the music to play, because I play this game when I have time that is when I am traveling or at night while sleeping. So can anyone tell me how to turn off the music of this puzzle game?

Yap, it’s a nice game even I use to play this game in my iPod. to off the sound you have to click on option button, then go to settings and after that select audio settings then move your slider to left, now it will off the music and if you want the sound back move the slider right.
