Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

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

So . . . not that it's the reason I joined this transformer (the timing was just right), but I'm curious:

How does the "Win a Workout Wardrobe" part of this bet's title work? Are we just supposed to purchase it with our winnings? :-) Or has someone actually won some new spiffy spandex?

I won $100 gift card from this one back in September. I think they randomly pick people, but they do not post it.

Back in rounds 1 & 2 they drew ten names and each of those twenty people won a $100 gift card. I was one of them, I got an Outdoor Voices card which I used for a couple of shirts and running shorts. There was a post about it, but they took it down for whatever reason. Winners also got an email to work out the delivery of their prizes.

Wow! I made $161 profit from this bet AND lost 20 lb! I think I’m going to take a little break and then do another Transformer Bet to hopefully get to my goal weight. Right now I’m 12% away from that goal.

Yay!! I’ve joined the Harry Potter one starting in just over a week. I’ve really enjoyed this Transformer and don’t want to lose momentum!


I'm doing Healthy Wager for my next one. The payout is higher but you have to be more self accountable.

So I am confused a little bit about the math. Do we not get our monthly buy ins back? I won $317 but I payed them $210 in monthly buy ins. So really I only won $107 in profit. Is this correct? I guess I thought we were Also refunded the buy-ins if we won.

That’s correct. You don’t get your buy-in back on top of the round winnings. Your profit is how you calculated it.


“Only 107”...anything more than the buy in is profit. So just be like “cool. $107 in free money!”

  • Well the day has finally come! After a year I am saying goodbye to transformers. I've lost 70 pounds over the past year and made quite a bit of money! Perhaps I'll see some of you in a member maintainer. You can also follow me on Instagram at eatdiveloveblog. Now time to focus on training for my first marathon!

I have lost 76lbs so I am heading to the maintainers too. I wish there were higher payout ones! See you there!

I'll be joining the one starting 2/26! Can't join the earlier one as I'll be camping in Mexico during final weigh in :blush:

  • I felt so pretty in my black dress last night at our Military networking event. So proud to have lost almost 20 pounds this past 6 months, and so proud of my peers, and all of the military men & women that make sacrifices and do so much good each day. 🇺🇸

I must have misunderstood how the pots work - the last pot went from $110k to $59k. Does anyone know why?

Half of all bets go into the pot for Round 6 (the Grand Prize). The other half goes into Rounds 1-5. If a player betting monthly elects to drop out mid-game, the money they've contributed into the Round 6 pot remains in Round 6 pot.

Eliana M.

If you add up the pots of all 6 rounds it's the 110k, the 59k is just round 6 which gets split among the remaining winners I think. Looking at round 5, seems like only 200 people or so were left going into round 6

Congratulations to everyone who won! It’s not looking like I am one of them. I struggled with a couple medical diagnoses the last 2 months and have an appt. with a specialist set up for April. Sadly even a Dr. note could refund me any of my money. I worked hard, but turns out my body is fighting against me! I hope to try another one once we get this medical stuff under control!

Hope you get to feeling better. Don’t give up. I know it is easy to get discouraged. Keep going on your journey!
