How it works

Trade your friends on how eventful each World Cup match will be. No bookmaker, no real money held — just a shared scoreboard.

The idea

Every match is a small market. One side bets a game will be wild, the other bets it'll be tame, and whoever calls it better keeps the difference. The app records the trades, tracks who's up and down, and at the end tells you the fewest payments needed to settle up.

How a match is scored

Every match settles at one number:

Settlement = Goals × Corners × Cards

Goals — both teams combined.
Corners — both teams combined.
Cards — a yellow is 1, a red is 2. Add them up.

Because the three are multiplied, a single red card or a late goal can swing the result hard. A 0–0 settles at zero; a chaotic game can settle in the hundreds.

Example — Mexico 2–0 South Africa

Goals	2 + 0	2
Corners	both teams combined	4
Cards	3 yellows + 3 reds = 3 + 6	9
Settles at		2 × 4 × 9 = 72

Price and size

Each market shows a price in points— the market's live guess at the final settlement. Mexico–South Africa might trade around 60 before kick-off; it settled at 72.

You also pick a size in £ per point. At £2 a point, every point the settlement lands away from your price is worth £2 to you, up or down.

Buying and selling

Buy / go long

Betting the match is more eventful than the price. You win if it settles above where you bought.

profit = (settlement − price) × size

Sell / go short

Betting the match is less eventful than the price. You win if it settles below where you sold.

profit = (price − settlement) × size

The Bid is the highest price someone will buy at — sell into it if you want out now.
The Offer is the lowest price someone will sell at — buy from it if you want in now.
The Market price is the current fair value (last trade, or the bid/offer midpoint) — what your open position is worth so far.

Take a price that's already there, or post your own and wait. When a buy and a sell meet at the same price, they match automatically.

A worked trade

Mexico–South Africa is marked at 60. You and a friend disagree:

You buy at 60, size £2/point — you expect a lively game.
Your friend sells to you at the same price and size.

It settles at 72 — that's 12 points above the trade, at £2 a point:

You (buyer)

(72 − 60) × £2 = +£24

Friend (seller)

(60 − 72) × £2 = −£24

Every trade is zero-sum: your £24 gain is your friend's £24 loss. The exchange never takes a cut.

Live play and settling up

Kick-off. When a match kicks off, any bids or offers left in the book are cancelled automatically unless you opted-in to keep them live. This prevents stale orders from executing after you've forgotten about them or gone to bed.
Live. Once a match is in play, goals, corners and cards update automatically and the running Goals × Corners × Cards moves with them. You can keep trading in-play.
Settlement. At full-time the market locks at the final number and your open profit becomes realised.
Leaderboard.Every trade is summed to show who's up and down across the tournament.
Cash up. At the end the app nets everyone off into the fewest payments needed. Settle those between yourselves.

Opting in to keep bids and offers live

Before you place a bid or offer, you can choose to keep it live after kick-off. Here's why you might:

You're expecting to trade actively during the match and want a standing order to catch someone.
You're placing a thin bid or fat offer on purpose and want to wait for in-play movement to hit it.

By default, bids and offers are cancelled at kick-off (like Betfair) — making the market fairer, because only traders actively watching in-play stay in the book.
