Here are the instructions on how to play the game.

1. Click on the level you want to start at.
2. The screen will now have a black square on it.
3. Use the arrow keys on your key board to move the snake around and try to pick up the blocks that appear on the screen. The object is to try to get as many blocks as possible before you run into the side of the screen.
4. As soon as you hit the first arrow key will start to move in that direction. Sounds simple but I suggest you start with the beginners level until you get used to it.

Have fun so lets go play.
