+<p>
+The game involves controlling a single block or snakehead by turning only left or right by ninety degrees until you manage to eat an apple. When you get the apple, the Snake grows an extra block or body segment.
+If, or rather when, the snake bumps into the edge of the screen or accidentally eats himself the game is over. The more apples the snake eats the higher the score.</p>
