你知道吗？最近有个游戏在朋友圈里火得一塌糊涂，那就是传说中的“三七倍数游戏”。是不是听起来就有点刺激？别急，让我带你一探究竟，看看这个游戏到底有什么魔力，能让那么多人沉迷其中。
一、游戏起源：神秘的三七倍数
这个游戏起源于一个简单的数学原理——三七倍数。简单来说，就是任意一个数字，乘以3再减去3，得到的结果再乘以3再减去3，如此循环，最终会发现，无论从哪个数字开始，都会得到7这个数字。不信？那就来试试吧！
比如，我们从数字2开始：
2 × 3 - 3 = 3
3 × 3 - 3 = 6
6 × 3 - 3 = 15
15 × 3 - 3 = 42
42 × 3 - 3 = 123
123 × 3 - 3 = 366
366 × 3 - 3 = 1093
