Both Teams to Score, or ‘BTTS’ as it is often abbreviated, is a bet that requires each team to score during a match in order to win. In fact, it’s a parlay consisting of two wagers - Team 1 to score/not to score and Team 2 to score/not to score.
This type is divided into ‘BTTS - yes’ and ‘BTTS - no’. If at least one goal is scored by both teams, the first wager is seen as profitable. Negative (second) wager wins if at least one of the teams does not excel in the match. Otherwise, failure is what will happen. The system particularly applies to full time. Extra time and penalties are not included in calculation.
