This is a demo of a program that uses high scores - it was primarily intended as this, hence the rather quick-to-finish game being demonstrated.
The numbers will randomly flash at you between 1-10,000, you've got to wait for a high one and then click the red button as soon as you see one. When you do, you'll be asked to enter your name.
After this, the scenario should display a list of the top 10 names along with the numbers they achieved.
Open the scenario in Greenfoot.
Download the source for this scenario.

Well with the code as it is at the moment, the only way I can think of is to either withold the source completely, or to deal with all the highscore bit in a seperate class and then remove the java source code of that class before you upload - that way you'll hide the name of the scenario used on the highscore database.
That said, it was designed as a quick add on for people wanting to record scores for their games and not as a super secure thing at all ;)

I changed the code for it to go higher and accidently added me as anonomous, can you please delete it somehow?
mjrb4 writes (on 2009-1-20):
Think I'll just wipe the lot again ;)

Why can't greenfoot find the class highScore?
spaceblue writes (on 2009-4-3):
oh my....
highest score!
oh and @ mjrb4
due to there being no highScore.java, i sort of can't understand how this works.

They weren't here before... I think the highscores file was deleted from Greenfoot gallery.

The highscores seem to be not working altogether. I get the same error on My Speed3D scenario.
mjrb4 writes (on 2009-10-19):
Sorry guys, yes it is a problem with the highscores but I'm afraid it'll have to stay this way for a while at least - I had a look at fixing it quickly but it seems it's not a quick job.
