How to write your own computer game

Step 01 — Source the Scratch software

First download the software from the Scratch website (http://scratch.mit.edu). On the site you'll find examples of games and animations created in Scratch, as well as an excellent support section, which includes printable "Scratch Cards" that you keep by the computer to help master the controls. There's also an excellent reference guide that provides a comprehensive list of all the Scratch commands.
