I love the "idea" of this game. But the ads glitch ALL THE TIME! And when you do the challenge levels some of them are rigged so there is NO WAY to win! You can't control your screen, it scrolls by itself as you play, but then some of them just stop scrolling! You can't see the pins, the only pins available to see are ones that shouldn't be pulled! I can't stand games that cheat or are defective!!
