START HEREWhat makes an exchange different from a sportsbook
A sportsbook sets a price and takes the other side of your bet. An exchange only provides the meeting place. Prices come from customers, so the same event can be bet from either direction, and the operator earns through commission rather than through the gap between odds.
The counterparty is a person
When your back bet is matched, the money on the other side belongs to another customer who laid the same outcome. Neither of you is trading against a bookmaker who has already built a margin into the price.
You choose the direction
A sportsbook only lets you say an outcome will happen. The exchange also lets you say it will not happen. That second direction is called laying, and it is the feature that most readers find new.
Prices move with demand
Odds on the board are a queue of offers. If many customers want to back a team, the available price shortens; if many want to lay, it drifts. You can read this queue as a picture of opinion.
Cost arrives as commission
The exchange does not hide its fee in the odds. Commission is charged on net winnings in a market, so a market you finish with a loss carries no commission at all.
SIDE BY SIDECasino products and the exchange compared
Slots, roulette, baccarat and crash games all have a built-in house edge, which means the operator is the opposite side of every round. The exchange has no such edge in the price. These comparison pages put each product next to peer-to-peer betting so the economics are easy to see.

SMALL SCREENSReading an order board on a narrow display
The same mechanics apply however you reach the exchange. A few habits make the board easier to read when the screen is small.
Back column versus lay column
Prices to back sit on one side and prices to lay on the other. Mixing them up is the commonest early mistake, so confirm the colour or label before you tap.
Check the liability line
Before you confirm a lay offer, read the liability figure. It is the amount you could lose, and it grows as the odds get longer.
Watch for unmatched offers
An offer that nobody takes stays waiting at your chosen price. Review open offers before the event starts so nothing sits there by accident.
