本文介绍了一个基于Visual Basic开发的2048数字游戏。通过键盘控制数字方块移动，目标是拼出2048数字。提供了完整的源代码及游戏实现细节。

2048是比较流行的一款数字游戏，每次可以选择上下左右其中一个方向去滑动，每滑动一次，所有的数字方块都会往滑动的方向靠拢外，系统也会在空白的地方乱数出现一个数字方块，相同数字的方块在靠拢、相撞时会相加。不断的叠加最终拼凑出2048这个数字就算成功。

根据Gabriele Cirulli大神的源代码和参考网上大神的源码制作了这个VB版的2048。

好像从开始玩到现在从来都没有玩到过2048，（好吧，我的游戏技术不好），但是有了源代码...4096都不是梦，悄悄地改一个变量积分就刷刷的。

基于大量的函数制作，颜色用了VB的填充，因为不会dll动态数据库的使用，所有没有声音，没有精美的背景。

游戏玩法很简单：

上下左右移动键盘即可，点击New Game开始新一轮的游戏。

游戏代码:
