The Aussie version sounds a bit different. Frankly, I find it boring, mostly, although we've got a very energetic host (who is also quite smart and witty, although you wouldn't know it from THIS show).
The fascination - we don't have much up against it, it is on right before the news that I watch and difficult child 3 is trying to draft a computer program that will duplicate the game by calculating the deal offered using probabilities. So for difficult child 3 - the numbers, plus the calculation, are why he watches it.
We've got an oversupply of game shows in Australia right now. It's getting so we can't turn on our TV on any night of the week on any channel, and not see a game show. And when skill doesn't come into it - it's boring.
