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

  • My workouts from today.
    Pic in the left was my walk with my friend Sarah. Lots of hills, pushing the double stroller.
    Right was bootcamp. Time was off, was only 75 mins, but I forget to turn my watch off.
    Now, I’m tired lol. BUT, I’m so proud of myself for killing it today, and spending my Friday chasing my goals! Plan to do it the next two days also!

  • Brutal honesty time:
    Today has been a day. Like a real tough, overly ridiculous day. So inner child Heidi wanted all the bad stuff. Oh AND it’s raining so I was even more bummed I was gonna miss my workout.

    That’s when GROWN UP HEIDI stepped in.
    Grown up Heidi, was like rain? Psh, I got this. She texted her friend to walk at the mall instead. I got some walking in. And when inner child Heidi wanted to eat all the food (shark week) grown up Heidi cooked this meal and ate it.

    Now, I know this sounds ridiculous, but there is totally a present and future version of yourself. Present Heidi is a little angry, because this is not what i wanted today, BUT future Heidi, will thank her ten times over tomorrow when she steps in the scale.

    We sometimes have to parent our inner child just like our own kids. Sure, I’d LOVE to say adult Heidi wins every time, but that simply wouldn’t be true. But today, adult Heidi prevailed. And that’s what matters right? One day at a time you guys!

    Our bet starts soon guys! I shared this with my current betters, but it’s a relevant message for you guys too! Let your adult self win you guys. Future you will thank you later ❤

I’m still so confused with the payment winnings of the transformer 😆 I’ll never get it! I always feel like I’m losing money with it LOL but I am amazed to say I’m entering round 4 down 49.4lbs with a goal of -22.5lbs from total goal weight! I think it was the kickstarters/transformer combo combined with my already fitness journey! Thank God I’m so heavy that the limit is still farrrr away 😆 A solid 100lbs to go for personal though! 💪

Yes, and to add to Graces point, with winnings from Rounds 1-3 so far, and getting just our money back for Round 6, we’re already at $150 basically. So whatever we “make” for Round 4, 5, and 6 now is all extra


Sorry, all of Round 4 will be profit, all of Round 5 will be profit, and anything above $87.5 in round 6 will be profit now :)

I made the mistake of playing 2 games at once and thought they ended same time but I was wrong and missed my weigh in. A little pissed off about it but my own fault and won’t make that mistake again

Send them an email. I made a similar mistake and since they could see I was at the weight with a verified weigh in during the window, they made an exception. I do six games at a time, and it can be confusing especially when the titles are similar

If i haven’t made my goal (I’m actually back to my starting weight) should I bother to weigh in? If I don’t will I stop getting charged? (Money is tight...)

Try to play other games simultaneously like runbet, Stepbet and one month dietbets so you can win those & make the $ again Don't give up on weight loss if you're not winning this game. Keep going <3 my best wishes!!

brandy h.

Keep trying! I’ve only lost 3 lbs the whole time. I’m still going to try because the end is what counts for me. We can do this! The money is coming out in way so why not try.
