To play this game, you need to write a program that completes the challenge. In this level, the challenge is to get all the beacons. Watch out--the level re-generates itself every time you play! You may want to press start a few times until you understand the pattern. All you need to do is add to the Robot's Start block. Then press the green flag to see if your program works. (I suggest playing this on Turbo Mode, which is in the Edit menu at the top of the screen.)
