1. The prize money total stands at over £37 million - that's more than any other daytime show in the history of British television.
2. On the other hand, Olly Murs's prize money total - after one pre-X Factor and one post-X Factor appearance - stands at a mind-blowing £10.50. (He is also the only person to play the game twice.)
3. If you fancy winning £250,000, best to have a single digit box. So far, the £250,000 has been hidden inside box 6, box 5, box 4, box 2, and twice in box 8. (I mean yes, it's all random so really this doesn't give you any clues but shhhh.)

5. 12 celebrities have played for charity andLouis Walsh did best, winning £70,000.
