(Hat tip to the commenters at bothersbar.co.uk for finding this; haven't seen it mentioned here.)
Looks like Series 1 of The Answer Trap had a problem with the arrangement of answers on its boards. Turns out that (almost?) every time, the answers that fit in each category were arranged
in alphabetical order on the game board, with the traps in random locations. If players discovered this pattern, they could get a definite advantage in the game.
I made a quick 'n' dirty graphic from one of the rounds in Episode 1 to show this. In each of the three categories, the correct answers are indeed alphabetical when reading left-right and top-bottom!
