Game has an annoying feature. Sorry I purchased it since the sound effects can not be turned off. – Grammar Pop HD Review

All the better App games permit you to turn the sound effects on or off. This game does not. When playing, you are forced to deal with a constant noise that sounds like water bubbling loudly (it also sounds a little like a muffled snare drum playing). That annoying sound only goes away (briefly) when you win at identifying a word, and then you must listen to a triangle-like computerized carnival sound. And if that were not enough, there is an actual voice speaking at various times (spurring you on etc). All the sounds are invasive and make you realize that the creators have a dictatorial approach. You WILL play the game the way they want - no preferences are offered to you to customize the game, i.e., you may not turn off the sounds. Quiet, peace-loving souls of silence - Beware!!
