A simple Gobang is implemented using a simple algorithm:

CSS code:

*{margin:0;padding:0}
img{
margin-left:20px;
height:630px;
width:1300px;
Position:absolute;
}
canvas{
Display:block;
Margin:auto;
Box-shadow: -2px-2px 2px #EFEFEF, 5px 5px 5px #B9B9B9;
Background: #886600;
position:relative;
top:50px;
}

HTML code:

<! DOCTYPE html>
<meta charset= "UTF-8" >
<title> Man-Machine edition Gobang </title>

<body>
<canvas id= "Canvas" width= "height=" 580 "></canvas>
</body>

JS Code:
