Please help identify this 80's show.
 

I believe there were three main characters, two boys and a girl. The show revolved around them solving various problems using a computer. In one episode, they play a computer game where they have to escape from somewhere. The game is apparently sent to them by someone they don't know, because once they've beat the game, they find out that they have shown this stranger how to break out of prison! I'm guessing it didn't last more than a season.

Maybe it was Wiz Kids

sorry never saw it.

It's definitely WHIZ KIDS...the plot you describe sounds like Episode 2 of this one-season series:
