Meaning of under 2.5 in betting
When placing a bet, « under 2.5 » means that the total number of goals scored in the game by both teams will be two or less. So if you placed a bet on « under 2.5, » and only one goal was scored in the entire game, your bet would have won because there were not more than two goals scored in the game. Conversely, if three goals were scored in the game, your bet would have lost because more than two goals were scored.
Many people use this betting system to bet on games that they think will be low-scoring since there is a higher chance of winning with this bet.
