Two calculations
Total goals
Add the goals by both teams, then compare the sum with the stated line.
Both teams to score
Check whether each team recorded at least one goal in the stated period.
Hypothetical total: 2.5
Combined goals = 2 + 1 = 3. Because 3 is above 2.5, Over 2.5 matches; Under 2.5 does not.
A half-goal line avoids equality. Whole-goal lines and three-way total markets can behave differently, so their exact settlement rule matters.
Hypothetical BTTS checks
Each side scored, so BTTS Yes matches.
Only one side scored, so BTTS No matches.
Neither side scored, so BTTS No matches.
Period and exceptions
Half-time, normal-time and extra-time markets are not interchangeable. Awarded results, abandoned matches and later corrections are handled by platform rules, not by the arithmetic above.
