使用Python编写拼图益智游戏

大家一般都玩过拼图益智游戏，或者类似的游戏。今天，就给大家使用pygame库在Python中构建一个拼图益智小游戏。这个拼图小游戏是构建一个围绕着将1-15个数字排列在16个方块的网格中的游戏。

现在，让我们从今天的惊人项目“使用PyGame的Python益智游戏”开始。首先，我们将对游戏背后的主要逻辑有一个基本的想法，然后我们将继续讨论我们将添加到这个项目中的功能，然后我们将会继续讨论这个项目的实际编码部分——Python益智游戏

游戏的基本规则和玩法：

在Python中的这个拼图益智小游戏，玩家必须按升序排列从1到15的块。游戏将显示16个方块，其中一个方块为空，玩家可以移动这些方块。一旦所有的方块都按顺序排好了，比赛就结束了。

既然我们已经对到底需要开发什么有了基本的想法，让我们继续往下看Python中拼图益智游戏需要实现的功能列表：

Python中益智游戏的特点：

Python中益智游戏的自动洗牌功能。

重置、新游戏和自动求解选项。

Python中的益智游戏块可以使用箭头键或鼠标移动。

下面直接给出Python拼图益智游戏的完整代码：
