How it works
One sideOdds are just a chance in disguise. -122 means you risk $122 to win $100, which works out to about a 55% chance.
Both sidesAdd up both sides and you'll usually get more than 100%. The extra is the app's built-in cut. Remove it and you get the fair chance.
Compare appsThe same prop can pay differently from app to app. Lower chance means a bigger payout, so we point out which pays the most.
