Yeah I wondered too, I reckon contestants have a tea break, curtains come down to hide boxes, then a runner goes round and checks all the boxes, and changes them, or something like that. I reckon it's a fix too, otherwise how come no-one's won �250,000 yet, but then Iam a bit of a cynic when it comes to game shows, and reality shows, dont even get me started on Big Brotherf@ker!
