Football betting glossary

Twenty terms used across the site. Each definition links to a worked explanation and its sources; operator rules still govern settlement.

Accumulator
A bet that combines selections. A losing non-void leg normally loses the combination; the applicable bookmaker rules determine settlement. Explanation and sources.
Leg
One selection within an accumulator or multiple. Explanation and sources.
Double / treble / fold
Two selections make a double; three make a treble. A four-fold contains four selections. Explanation and sources.
Decimal odds
A price format that includes the returned stake. Multiply stake by decimal odds to calculate the total return on a winning, unadjusted bet. Explanation and sources.
Total return
The amount paid back by a settled winning cash bet, including the returned stake. It is not the same as profit. Explanation and sources.
Profit / loss
Total money returned minus all stakes counted. Promotional stakes can have different return rules. Explanation and sources.
Implied probability
The reciprocal of a simple decimal win price is its break-even threshold, not proof of the true chance. Explanation and sources.
Overround
The amount by which the reciprocal prices of all mutually exclusive outcomes exceed 100%. It is not a guaranteed realised profit margin. Explanation and sources.
Estimated edge
Offered decimal odds multiplied by estimated win probability, minus one. It depends on the probability estimate being appropriate. Explanation and sources.
BTTS
Both teams to score. BTTS Yes requires each team to score at least once in the specified scoring period. Explanation and sources.
Goals line
The threshold used for an over or under selection. Half-goal lines cannot be matched exactly by an integer goal total. Explanation and sources.
Draw no bet
A match-result market with draw-specific void or refund treatment. Read the bookmaker's market rules before combining it. Explanation and sources.
Void
A selection or bet cancelled under the applicable rules. An ordinary void acca leg is often removed or treated at 1.00, but special products can differ. Explanation and sources.
Correlation
A relationship between outcomes. If outcomes are not independent, multiplying standalone probabilities does not establish their joint chance. Explanation and sources.
Bet builder
A same-match combination that needs its own accepted bookmaker quote. Standalone market prices cannot simply be multiplied. Explanation and sources.
Cash out
An offered early settlement, subject to availability and operator conditions. It is not a guaranteed exit or a refund promise. Explanation and sources.
Free bet / bonus credit
Promotional value with conditions, not automatically withdrawable cash. Whether its stake is returned is material. Explanation and sources.
Wagering requirement
A stated amount of qualifying betting required by an offer. Check what amount the multiplier applies to and which bets count. Explanation and sources.
Deposit limit
A restriction on deposits during a defined period. Gross and net definitions differ; the operator's displayed definition matters. Explanation and sources.
Unpriced
On this site, no supported combined bookmaker quote is available. No combined return, edge or win-probability claim should be inferred. Explanation and sources.
