It's the 1960s, and real nerds prove their mettle in the Robo-Wars! Program your robot in RoboBASIC using punchcards and send it into the arena. Share your RoboBASIC code with others by pasting the encrypted program text into the Comments to see how it fares against other players!

If you're hard core, you can program your punchcards by punching holes in it. If you're a wuss, you can type your code into the input field, and the game will punch the card for you. :-)
