BTTS & Over/Under 2.5 goals

BTTS is a yes/no question about a match: it is "Yes" when both teams score at least one goal, and "No" if either team is kept off the scoresheet — the result itself does not matter. The table shows how common scorelines read:

Result	BTTS
1–1	Yes
2–1	Yes
3–2	Yes
1–0	No
0–0	No
2–0	No

BTTS is a popular stat because it ignores who wins and focuses purely on whether the game is open at both ends.

Over/Under 2.5 counts the total goals scored by both teams combined: "Over" needs 3 or more, "Under" means 2 or fewer — and the .5 exists so a match can never sit exactly on the threshold. The table shows how totals read:

Total goals	Over/Under 2.5
0, 1, or 2	Under
3 or more	Over

The threshold is set at 2.5 rather than a whole number on purpose: a match cannot end on 2.5 goals, so every result is clearly one side or the other, with no in-between. 2.5 is the most common threshold because the average top-league match tends to hover near it.

Because ScoreGPT's models output a predicted scoreline for each match, that scoreline answers both questions directly — the table shows the mapping.

Predicted scoreline	BTTS	Over/Under 2.5
2–1	Yes	Over 2.5
1–1	Yes	Under 2.5
1–0	No	Under 2.5
3–2	Yes	Over 2.5
0–0	No	Under 2.5

The consensus scoreline gives a single read across the five models. A predicted scoreline is an estimate, not a result: it is graded against the real score after full-time, wins and losses alike.

Want the live version rather than the definition? ScoreGPT reads three calls off its daily AI consensus scoreline and grades them in public after full-time: correct score predictions, over/under 2.5 goals predictions and both teams to score predictions. Each page lists the covered fixtures for the day with the call read from the scoreline, and a rolling 7-day count of hits and misses — a count, not an accuracy claim.
