It looks like a sportsbook — live odds, parlays, player props, prediction markets — but every bet settles in something you have to actually do. Forty push-ups. A week of dishes. Date night, planned by the loser.
These are the actual screens — swipe through. Everything a book has, minus the part where somebody takes your money.






Not cash, not an e-transfer, not a gift card, and not "loser buys the wings" — buying something for somebody is a transfer of money wearing a disguise, and a platform that settles bets in transfers of money is a gambling platform with extra steps.
So the app cannot hold a currency amount anywhere in it. There is no balance, no deposit, no cash-out. A stake is a count of a thing a person does, and the ledger is denominated in push-ups.
A fight, a game, a gym session, whether your friend turns up when they said they would. Anything with an outcome and an argument attached.
Singles, parlays, round robins, teasers. Combine legs off the same event — the engine prices the overlap properly instead of banning it.
Every ticket is one person against another. Name your opponent or post it open and let the crew fight over it.
The loser films the forfeit in the app, scoreline and rep counter burned into the video. The winner confirms it, and only then does the debt clear.
Every ticket makes a card sized for a story or a group chat. Send it to your partner and they can cheer for you or against you without signing up for anything — and whoever loses is doing the dishes either way.
A debt is due three days after it settles. Miss it and your badge goes red in front of the whole crew, and you cannot post a new bet until the video is in. Pay on camera and your form climbs.
Every slip here is priced fair, so every slip can show you the cut a book takes on the same bet. It compounds with every leg:
No price on this board was bought from anybody. For each league, completed results are walked in date order and a rating is updated after every game; those ratings give a spread and a total, and every other market falls out of that pair by arithmetic — the way a trading desk does it. How well it works is published, not asserted: each league shows its Brier score against a coin-flip baseline, including the ones that barely beat chance.
NFL, NBA, NHL, MLB, college football and basketball, the Premier League, MLS, the Champions League and UFC. Adding another is a row in a config file.
Football and basketball get a Normal margin. Soccer, hockey and baseball get a Poisson score matrix, so correct score, both-teams-to-score and clean sheets come out of the same joint distribution instead of being guessed separately.
Method, round and distance come from one finish-rate model, so “wins by knockout” and “ends inside two rounds” cannot contradict each other on the same slip.
Counting stats are overdispersed, not Poisson — a 24-point scorer goes for 35 far more often than Poisson believes. Props are priced negative-binomial, and two lines on the same player are recognised as nearly the same bet.
Questions worth arguing about, taken from the public prediction venues. Their wording, never their prices — these open at even money and move on how your crew votes.
Comparative longevity between public figures, priced from survival curves on age and sex alone. No dated death markets, ever — only which of two people comes second.
A sportsbook mostly refuses to let you combine legs from one event, because correlated legs are how a book gets robbed. "Vega wins by knockout" and "the fight ends inside two rounds" are close to the same bet — multiply their prices together and you have sold a 4x parlay for 9x.
1v1 has no house to protect, so it does the other thing: it prices the overlap and shows you the working. Every correlated pair on your slip is listed with its coefficient and a sentence of English, and the naive number sits next to the honest one with a line through it.
Two legs are integrated exactly. Three or more go through a Gaussian copula over the correlation matrix, seeded from the leg ids so the slip prices identically on both your phones.
Because a knockout is an early finish and an early finish usually involves a knockdown. You were being offered three prices for roughly one opinion — the honest price is 59% below the naive one.
Every stake is capped, and the caps bite after the multiplier — which is the only place they matter. A 40-push-up stake on an 18x slip is 720 push-ups, and somebody would try to do them in one sitting.
Push-ups, burpees, squats, plank, kilometres run. Capped hardest, splittable across the day, and switchable off entirely per person.
Dishes, dog walks, garbage nights, the driveway after it snows.
Rides, covered shifts, surrendered movie picks. The currency of actually knowing somebody.
Their photo as your avatar for a week. Naming rights over the group chat. Silence on the subject.
Karaoke of their choosing, a limerick in their honour, a highlight reel you have to edit.
Minutes of a chore they pick. The most flexible unit and the most dangerous one to owe.
Name it, send one link to the group chat, and everybody's phone shows the same bets, the same ledger and the same trash talk. No accounts. No emails. No money.
