BTTS ("both teams to score") comes as Yes or No. BTTS Yes lands if each team scores at least one goal. BTTS No lands as soon as one team stays on 0. It often moves with Over/Under, but it asks a different question: a 3-0 wins Over 2.5 and loses BTTS Yes.
So what is BTTS?
BTTS stands for Both Teams To Score. Two outcomes: Yes if each team scores at least one goal, No if either side stays on 0.
The total number of goals? The market doesn't care. Who wins the match? Doesn't care either. The only thing that counts is whether each team got on the scoresheet at least once.
Settlement table
| Score | BTTS Yes | BTTS No |
|---|---|---|
| 0-0 | Lost | Won |
| 1-0 | Lost | Won |
| 1-1 | Won | Lost |
| 3-1 | Won | Lost |
| 0-4 | Lost | Won |
Look at the last row. A 0-4 means four goals, yet only one team scored. BTTS No wins. The total plays no part at all.

Edge cases: own goals, extra time, abandoned matches
An own goal counts for the other team. If a side's only goal comes from an opponent putting it into their own net, that side is still treated as having scored. So a 1-1 that comes about this way still wins BTTS Yes.
The market usually covers normal time only, stoppage time included. Extra-time goals don't count unless the operator says otherwise. That matters most in cup ties, where a draw can go to extra time: anything scored after 90 minutes plus stoppage time is typically left out of settlement. Match abandoned and not replayed the same day? Bets are usually voided and stakes returned. Fixture just postponed? Most operators keep existing bets live until the new date. The exact rules vary from one operator to the next, so check them before you bet.
Margin and implied probability on BTTS
You read BTTS with the same tools as 1X2 or a handicap. Every price has a margin built in and converts to an implied probability. A price of 1.80 on BTTS Yes works out at roughly 55.6% implied probability. The maths is the same as on any other market, and it's laid out on the implied probability page.
Add up the implied probabilities for BTTS Yes and BTTS No. You'll usually go over 100%. That extra is the bookmaker's margin, covered on the bookmaker margin page. The margin on a given fixture isn't fixed, either. It can shift with the competition, the two teams' scoring record and how much money the market is expected to attract.

What does BTTS mean?
It stands for Both Teams To Score. There are two outcomes. Yes if each team scores at least one goal, No if either side stays on 0.
When does BTTS Yes win?
As soon as both teams have scored, whatever the final score. A 1-1 is enough. So is a 4-3.
When does BTTS No win?
As soon as one team finishes the match without scoring. Even on a rout like 5-0.
What's the difference between BTTS Yes and Over 2.5?
BTTS Yes checks whether both teams score and ignores the goal count. Over 2.5 counts the goals and ignores who scored them. They often go together, but they're answering two different questions.
Does a 3-0 score win BTTS Yes?
No. Only one team scored and the other stayed on 0. BTTS No wins, even with three goals on the board.
Does OddScore track the BTTS market?
No, BTTS isn't one of the markets the platform analyses. This page just explains how it works.
