In Sportybet, "Over 2.5" refers to a football betting market where customers bet on three or more goals being scored in a 90-minute football match. The ".5" in the 2.5 is used to prevent any confusion. If there are exactly two goals scored, then the bet will be lost. The bet is for the ninety minutes of the football match, plus any additional injury time that the fourth official declares at the end. Any goals scored in extra time or from penalties will not apply to the total.
