Tennis markets use the event format and a defined scoring or settlement question. Tennis has points within games and games within sets. A match tie-break may replace a deciding set in some formats, so the competition format changes how a total can be interpreted. An illustrative 6–4, 6–4 result contains 20 completed games, while its set score is 2–0.
A market is a precisely defined question
A market title specifies what will be measured. Match winner asks for an outcome; a total asks whether a measured quantity finishes above or below a line; a player market concerns a named participant. The same fixture can contain many questions with different winning conditions.
A tennis match winner, set winner, game handicap and total-games market answer different questions. Singles and doubles are separate events. A deciding match tie-break can have a special treatment in game-total settlement under the listed rules.
The selection receipt preserves the accepted market name, line and price. These details matter if the interface changes while the event is underway. Descriptions such as popular or featured do not alter settlement. Two selections can share a team name but still concern unrelated measurements, so identify the complete proposition rather than the name alone.
Decimal Odds and Return Calculations
Decimal odds include the original stake in the total return. In a hypothetical example, a 100-unit stake at 2.40 returns 240 units if the selection wins: 140 profit plus the original 100. A losing selection returns nothing under ordinary win-or-lose settlement. These figures illustrate arithmetic, not a forecast.
