How Tennis Point Spreads Work at upupcasino

A margin set by oddsmakers that a favorite must exceed, or an underdog must stay within. It turns a lopsided match into a two-sided wager based on games or sets, not just the winner.

Against the spread — whether a player covered or failed to cover the set game margin. Tracking ATS records on specific surfaces helps evaluate whether a line is priced accurately.

A spread listed with a .5 (like -3.5 games) that eliminates a push. No match ends on a half-game, so the wager always settles as a win or a loss, never a refund.

Line movement means oddsmakers adjusted the spread after new money came in or new information arrived — injury reports, weather, surface conditions. It signals where sharp money is landing.

A set spread counts only the number of sets won. A game spread counts every individual game across the whole match. Game spreads offer more granular margins and typically higher variance.

When the margin lands exactly on the spread number — only possible without a half-point. The wager is voided and your stake is returned to your account balance automatically.
