Both Teams To Score is exactly what it says: yes if both sides find the net at least once, no if either keeps a clean sheet. It is one of the most popular football markets in Ireland because it keeps the whole match alive — you need two events, not a winner. That popularity is also precisely why it deserves a cold look at the maths.
How BTTS settles
Normal time only, own goals count for the team they are scored for, and the final score is all that matters — 1-1 and 4-3 both land “yes”, while 3-0 lands “no” however one-sided the chances were. There is no draw, no void, no grey area: two outcomes, settled at the final whistle. Like any two-way market, that makes the margin easy to measure — convert both prices to implied probability and add them; the excess over 100% is the house cut.
Why BTTS is acca fuel
BTTS prices usually sit in the evens-ish band on well-matched fixtures, and that band is the sweet spot for accumulator builders: short enough to feel safe, long enough to multiply quickly. Five BTTS legs around evens compound to roughly 30/1 odds — which is why Saturday coupons push BTTS accas so hard. The honest-maths catch: the margin compounds too. If each leg carries a few percent of house edge, a five-leg acca carries five of them multiplied together. The bookmaker’s cut on the acca is far bigger than on any single — that is the price of the dream, and you should know you are paying it.
BTTS and over 2.5: cousins, not twins
BTTS yes and over 2.5 goals are strongly correlated — matches where both teams score tend to produce goals — but they are not the same bet. 1-1 wins BTTS and loses over 2.5; 3-0 does the opposite. Combining them in a “BTTS & over 2.5” special is popular, and here the correlation works for the bookmaker’s presentation: because the outcomes overlap heavily, the combined price is much shorter than multiplying the two separate prices would suggest — and the margin on the combined market is typically fatter than on either parent market. If you already believe in one of the two, the cleaner bet is usually just that one.
The form stats that matter
Useful BTTS homework is narrow: how often each side scores, and how often each side concedes — shown in most league tables as goals for and against, and in “clean sheet” and “failed to score” counts. A team that rarely blanks facing a team that rarely keeps clean sheets is the profile, in both directions. Beware small samples dressed as trends: “BTTS has landed in four straight” is four coin flips, not a law of nature. Season-long scoring and conceding rates beat streaks every time.
The honest summary
BTTS is a fair, simple two-way market when bet as a single with the margin checked. It becomes expensive the way most markets do — stacked into accas or fused into combo specials where the house edge multiplies quietly. Enjoy it for what it is; count what it costs.

Frequently Asked Questions
Own goals count for the team they are scored for on the scoresheet. If the own goal gives the second team its goal, BTTS “yes” lands. Settlement is purely the final score after normal time — extra time in cup ties does not count.
No. They are correlated but settle differently: 1-1 wins BTTS and loses over 2.5; 3-0 does the reverse. The combined “BTTS & over 2.5” special typically carries a fatter margin than either parent market — if you believe in one leg, betting that leg alone is usually the cleaner value.
Because evens-ish prices compound into big headline odds fast — five legs around evens is roughly a 30/1 ticket. The catch is that the margin compounds too: five legs of house edge multiplied together make the acca far more expensive, proportionally, than any single BTTS bet.
