    Nay, CEO of Nay Games, is a 14-year-old boy from the U. S. Several months ago, he began to {#blank#}3{#/blank#}（开发） the new free game for the Apple iPhone, Bubble Ball.

For the last few weeks, the popularity of the game has {#blank#}5{#/blank#}（上升） worldwide. It is {#blank#}6{#/blank#}（注意到） to have been downloaded more than 6 million times from the Apple Store.

    In the game, players have to get a ball to the finish line. The game gets more and more difficult as players move objects around, which attracts players to {#blank#}7{#/blank#}（尝试） again and again. Nay says, "I designed the game program at the local public library."

    The {#blank#}8{#/blank#}（成功） of Bubble Ball set up the stage for Nay to pay for his next {#blank#}9{#/blank#}（发明）. He has already {#blank#}10{#/blank#}（完成） an update（更新） on the game with levels and a more beautiful look on the larger iPad screen. Nay has a bright future in game development.
