You control the head of the snake by using the cursor keys.
Clicking the left arrow key changes the direction of the head to point East, Left to West, Up to North and Down to South.
The head keeps moving in the same direction until an arrow key is clicked to change its direction.
Don't hit a wall and don't bite your own tail.
Crashing into a wall or your tail will end the game immediately.
Your high score is calculated based on the number of squares you added to the snake.
You win the game when there is no more room for your snake to grow.
