Bet your friends.
Just not for money.

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.

  • No deposit, no payout, nothing to buy — ever
  • Real odds on every NFL, NBA, NHL, MLB, soccer and UFC game
  • Poker nights, callouts, streaks and a live ledger with your crew
What you'll see

A real sportsbook. Paid in push-ups.

These are the actual screens — swipe through. Everything a book has, minus the part where somebody takes your money.

The one rule

Nothing with monetary value is a valid stake.

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.

How it goes

Put something up

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.

Build the slip

Singles, parlays, round robins, teasers. Combine legs off the same event — the engine prices the overlap properly instead of banning it.

Somebody fades you

Every ticket is one person against another. Name your opponent or post it open and let the crew fight over it.

Post the proof

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.

Share the slip

Now she cares about the fourth quarter too

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.

Proof or bad form

Welching has a cost here

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.

The reality check

What a sportsbook would have kept

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:

One leg5%
Four-leg parlay17%
Ten-leg parlay37%
The whole table →
The board

Every sport, priced here rather than copied

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.

🏟️

Ten leagues

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.

📐

The right distribution

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.

🥊

Fights that reconcile

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.

👤

Player props

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.

🗳️

Event contracts

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.

⚰️

Who outlasts whom

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.

Deep parlays

The same-game parlay, priced honestly

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.

A three-leg slip on one fight
Vega by knockout3.85x
Under 2.5 rounds2.27x
At least one knockdown1.64x
Multiplying the picks says14.33x
What it is actually worth5.87x

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.

The stakes

What you can actually put on the line

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.

💪

Physical

Push-ups, burpees, squats, plank, kilometres run. Capped hardest, splittable across the day, and switchable off entirely per person.

🍽️

Chores

Dishes, dog walks, garbage nights, the driveway after it snows.

🚗

Favours

Rides, covered shifts, surrendered movie picks. The currency of actually knowing somebody.

🖼️

Social

Their photo as your avatar for a week. Naming rights over the group chat. Silence on the subject.

🎤

Creative

Karaoke of their choosing, a limerick in their honour, a highlight reel you have to edit.

⌛

Time

Minutes of a chore they pick. The most flexible unit and the most dangerous one to owe.

Takes thirty seconds

Start a crew.

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.

  1. 1Name your crew — couples, roommates, the fantasy league, the office.
  2. 2Send the invite link. Anybody who taps it is in.
  3. 3First bet by halftime. Loser pays up on camera.
