Over:Under 1.5/2 (or 1.75 as an Asian Handicap) would mean the following:
If the score finishes over or under 2 / you win 100% of the wager - however if the score finishes EXACTLY at 2 on the total - half the wager is graded as a push.
So if you bet $100 on odds of +100 (or 2.0) and you took under and score finishes 0-0 you win $100 for a total return of $200 ($100 risk and $100 win). If the score finishes at 2-0 you would be returned $50 of your stake (losing the u 1.5 wager and pushing on the 2).
Similarly - the second example would be an Asian odds of .25 and would require the team selected to win outright - if the game finishes in a tie - half the wager would be returned (the pk) and half lose (the -.5).
.75 would require winning by multiple goals for both wagers to win - as your betting -.5 and -1, f the team only won by a single goal - the first half is a winner and the second is a push resulting in return of all risk and half of the to win amount. These types of bets require analysis and prediction, making them appealing to players who enjoy strategy and prediction. It's a bit like playing online casinos, where luck plays a role, as does understanding the rules and strategy. For example, at

Personally, I believe these types of bets add excitement and allow you to better understand each match, especially when you understand how to properly balance risk and potential rewards.
