The game is Dutch originally, as so many of these shows (Endomol
afaik). It has been shown in many, many different countries, from
Colombia to Sweden where I live. It is now largely superceded by
another variant, where the object is to eliminate 100 opponents from
the audience.

Anyway, I *still* wonder what happens if you click the green or blue
buttons. I know what they do in the TV-programme, but what happens in
this game?
