Make a Snake Game With HTML Codes Using Notepad

First, you have to copy the bellow codes:

<!documentTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Play Snake Game</title>
<style type="text/css">
body {text-align:center;}
canvas { border:5px dotted #ccc; }
h1 { font-size:50px; text-align: center; margin: 0; padding-bottom: 25px;}
</style>
<script type="text/javascript">
function play_game()
{
var level = 160; // Game level, by decreasing will speed up
var rect_w = 45; // Width
var rect_h = 30; // Height
var inc_score = 50; // Score
var snake_color = "#006699"; // Snake Color
var ctx; // Canvas attributes
var tn = []; // temp directions storage
var x_dir = [-1, 0, 1, 0]; // position adjusments
var y_dir = [0, -1, 0, 1]; // position adjusments
var queue = [];
var frog = 1; // defalut food
var map = [];
var MR = Math.random;
var X = 5 + (MR() * (rect_w - 10))|0; // Calculate positions
var Y = 5 + (MR() * (rect_h - 10))|0; // Calculate positions
var direction = MR() * 3 | 0;
var interval = 0;
var score = 0;
var sum = 0, easy = 0;
var i, dir;
// getting play area 
var c = document.getElementById('playArea');
ctx = c.getContext('2d');
// Map positions
for (i = 0; i < rect_w; i++)
{
map[i] = [];
}
// random placement of snake food
function rand_frog()
{
var x, y;
do
{
x = MR() * rect_w|0;
y = MR() * rect_h|0;
}
while (map[x][y]);
map[x][y] = 1;
ctx.fillStyle = snake_color;
ctx.strokeRect(x * 10+1, y * 10+1, 8, 8);
}
// Default somewhere placement
rand_frog();
function set_game_speed()
{
if (easy)
{
X = (X+rect_w)%rect_w;
Y = (Y+rect_h)%rect_h;
}
--inc_score;
if (tn.length)
{
dir = tn.pop();
if ((dir % 2) !== (direction % 2))
{
direction = dir;
}
}
if ((easy || (0 <= X && 0 <= Y && X < rect_w && Y < rect_h)) && 2 !== map[X][Y])
{
if (1 === map[X][Y])
{
score+= Math.max(5, inc_score);
inc_score = 50;
rand_frog();
frog++;
}
//ctx.fillStyle("#ffffff");
ctx.fillRect(X * 10, Y * 10, 9, 9);
map[X][Y] = 2;
queue.unshift([X, Y]);
X+= x_dir[direction];
Y+= y_dir[direction];
if (frog < queue.length)
{
dir = queue.pop()
map[dir[0]][dir[1]] = 0;
ctx.clearRect(dir[0] * 10, dir[1] * 10, 10, 10);
}
}
else if (!tn.length)
{
var msg_score = document.getElementById("msg");
msg_score.innerHTML = "Thank you for playing game.<br /> Your Score : <b>"+score+"</b><br /><br /><input type='button' value='Play Again' onclick='window.location.reload();' />";
document.getElementById("playArea").style.display = 'none';
window.clearInterval(interval);
}
}
interval = window.setInterval(set_game_speed, level);
document.onkeydown = function(e) {
var code = e.keyCode - 37;
if (0 <= code && code < 4 && code !== tn[0])
{
tn.unshift(code);
}
else if (-5 == code)
{
if (interval)
{
window.clearInterval(interval);
interval = 0;
}
else
{
interval = window.setInterval(set_game_speed, 60);
}
}
else
{
dir = sum + code;
if (dir == 44||dir==94||dir==126||dir==171) {
sum+= code
} else if (dir === 218) easy = 1;
}
}
}
</script>
</head>
<body onload="play_game()">
<h1>Play Snake Game</h1>
<div id="msg"></div>
<canvas id="playArea" width="450" height="300">Sorry your browser does not support HTML5</canvas>
</body>
</html>
Second Step: Now open your notepad file from your Computer.

Third: Now Paste the codes inside the notepad file and save it by the extension is Snake.html

By finished above options, now you are ready to play the game. Just click the icon where you save it and enjoy the games. You can edit it by changing the codes which I highlighted with others colour inside the code area.

Enjoy the game now which you make now by the HTML codes with notepad. If not working your codes don't forget to share or ask me anything via comment. Share this post on social media like facebook and twitter. Also, you can read How to Make Clock and Date Using Notepad Text Editor.
