Why are no High Scores recorded in the Arcade?

If you go to the Arcade section there are no High Scores recorded for any of the games. I played one of them myself and there was no option to record your high score. If I set up a forum I'd like to create a weekly competition where the high scorer gets a prize, but obviously this can only be done if the scores are recordable. Can you tell me why they can't be recorded at the moment? Thanks.

What game? I tried avoider on my forum here and it worked yesterday.

All the games on here... just click on Arcade and it shows 'no scores recorded' for every one. I played '0h h1' and it didn't give me the option to save my high score.

Sorry about that. That was a filed experiment with HTML5 games on this support forum using a 3rd party service. They don't support saving high scores.
Most of our flash games do support saving high scores.
