My spreadsheet tells me that in Trish's game (3 February), the amount the contestants could have won if they had made all the right decisions passed £100,000,000!!!!

By right decisions, I mean:

Opened the boxes in the order they were actually opened
Dealt at the highest offer if higher than the contents of their box, or no dealt throughout if their box contained more than the highest offer
Took advantage of any swaps offered if they would result in a higher win (including all cases where the £250k was still in play at 2-box)
Took the banker's gamble where offered if to their advantage
Achieved the results actually achieved in special tests (catapult etc), as it would be impossible to predict the offers if a different result occurred

I have ignored the value of bonus wins (holidays etc) and any sums payable to contestants not actually playing the game.

Actual winnings to the same date were just under £32.5m. Don't think this proves anything except that it is a game of chance!

Hmmm... I have it more in the region of £87.6million+, but as far as I gather, you have included times when the hypo swap has been offered and taken to bring £250k to the table? (Oh, and any times the player has won the lower amount from their box having been offered the swap?) Also, I haven't counted the catapult scenarios as an ACTUAL peak offer of game.
