One up, Two down简介

One up, Two down seems like a very simple puzzle game. You have to create numbers from 1 to 999 using the three digits, just like in a combination lock. First you increase one digit by one, then you decrease a digit by two. Then you increase a digit again, then decrease a digit by two and so on. What makes it tricky is that you can't modify one digit two times in a row. This means you really have to work hard to get the next number on your way to 999! 一上来，两下似乎是一个非常简单的益智游戏。您可以使用三个数字来创建数字从1到999，就像在一个组合锁。 首先，你增加一个数字接一个，那么你两减小数值。然后再次增加一个数字，然后由两个减少一个数字等等。是什么使得它非常棘手的是，你不能修改一个数字，连续两次。这意味着你真的要努力工作，让自己的方式在未来数到999！
