python快速实现2048小游戏

news2024/11/26 20:42:45

《2048》是一款比较流行的数字游戏，最早于2014年3月20日发行。原版2048首先在GitHub上发布，原作者是Gabriele Cirulli，后被移植到各个平台。这款游戏是基于《1024》和《小3传奇》的玩法开发而成的新型数字游戏。

操作指南：

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。

游戏技巧：

最大数尽可能放在角落。
数字按顺序紧邻排列。
首先满足最大数和次大数在的那一列/行是满的。
时刻注意活动较大数（32以上）旁边要有相近的数。
以大数所在的一行为主要移动方向
不要急于“清理桌面”。

完整代码如下：
