I liked this show a lot when it was on Channel 4 back in the days before widescreen broadcasts were in force.

The original host, Richard O'Brien (of "The Rocky Horror Picture Show" fame) set up all of the mini-games for the contestants to play in order to win crystals (a selection of physical, mental, skill & mystery challenges available).

The worst part is that the automatic lock-in only happens on some mini-games, giving the option to release a contestant in exchange for a crystal they previously won.

I occasionally watch this gameshow on Challenge just to check on their performance.

This show is one of the greatest things to come out of British TV! Loved Richard O' Brian and everythin about it! I have the intro on my computer

used to watch this show. its a very entertaining gameshow.
players were active in the maze... and to think it existed years before amazing race and other overrated reality gameshows

I remember watching this as a kid every saturday morning where we live. Awesome show.

Yeah, and a superb one at that. Richard O'Brien did a good job

So this was some sort of British Game show?
