Please try and increase your odd. Your odd are relatively low for most of the games.
The odds depends on the person who are betting. The more person who bets on one side makes the odds smaller. If you want a larger odds to win, bet on the side which has larger odds. But, those team/side that has larger odds means that that team has low chance of winning/ impossible to win that's why there are only few persons who bet on that team/side . Like for example, in NBA Basketball GSW vs. Jazz . You can see that the odds in the GSW is smaller than the odds in the Jazz. Because there are lots of person who bets on the GSW side because they have more chance of winning rather than the Jazz, because of this. The bets were not balanced, and so the odds makes it even.
