The difference between over 2.5 and over 2, meaning 1xBet, is easy to understand. Thus, if you place an over 2 bet, it wins if both football teams shoot 3 or more goals in a match. If they score 2 goals, you get your stake back. If your bet is over 2.5, it succeeds if the totals in this football match are 3 or more; this bet loses if the number of goals is 2.
