L 'Under and Over in a game show if there will be more or less than 2.5 goals. So if the game ends with less than 3 goals, that is, for example, 0-0, 0-1, 1-0, 1-1, winning the bet will be UNDER. Conversely, if the game ends with more than 3 goals, that is, for example, 2-1, 2-2, 1-2, and all the results above, the winning bet will be OVER. Usually most of the Bookmakers indicate the standard threshold of Under / Over 2.5 in, but you can also find upper thresholds (3.5 or 4.5) or lower (0.5 or 1.5) and you can also find Under / over reported only the first time.
Here are some examples of Under / Over 2.5:
Brazil - Italy 1-0. The sum of the goals is one that is less than 2.5 then the outcome will be UNDER Brazil - Italy 0-2. The sum is 2 that is less than 2.5 then the outcome will UNDER Brazil - Italy 1-2. The sum is 3 that is greater than 2.5 then the outcome will be OVER Here are some examples of Under / Over 3.5:
Brazil - Italy 2-0. The sum is 2 which is less than 3.5 then the outcome will UNDER Brazil - Italy 1-2. The sum is 3 which is less than 3.5 then the outcome will UNDER Brazil - Italy 3-1. The sum is 4 that is greater than 3.5 then the outcome will be OVER Here are some examples of Under / Over 0.5:
Brazil - Italy 0-0. The sum is 0 which is less than 0.5 then the outcome will be UNDER Brazil - Italy 0-1. The sum is 1 that is greater than 0.5 then the outcome will be OVER Brazil - Italy 2-2. The sum is 4 that is greater than 0.5 then the outcome will be OVER
