Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.
Check out the FAQ to learn more!

How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

  • I needed to see this today. When I got on the scale yesterday, I was mildly shocked that I had gained weight and started the “woe is me” crap and “it’s never going to happen for me” crap. Had to look deep, be objective and realize that I have to keep going and be smart about it. When I reviewed last week’s food log, I see where I can improve (not restrict...there’s a difference). I’m also ill and haven’t been at the gym as much so I need to adjust calories accordingly, See...there it is...all the emo aside.

Ugh- I’m probably going to miss this weigh in :( This is my first Transformer game- do I just lose the round and continue toward the next goal? Or do I get disqualified from the entire game for not making the goal for this round?

The only mandary weigh in before the final is round 5. Even that one you don't need to win, but get to at least 6 percent loss.

Biking Syl

Weigh in regardless, though. That way you are less likely to be required to do a video weigh in.

Just in case there are any questions, check out the Transformer rules and the FAQ. It helps me to re-read them every so often. It can be a bit confusing, so feel free to ask.

Write to support for any tech issues or other questions regarding the game, which are not answered:
