Football asian handicap works differently to other sports

[Kidmat]

Just learned this recently when I bet on football then I saw a 1.51 odds on +0.25 to a winning team with 1:0 score and only few minutes remaining on the game time.

I taught this is a steal odds since I used to bet on other sports before like basketball that odds is straight up with handicap being offered.

But on football, you will be paid half if the team you bet on didn’t score at all until the match end. The team you bet on need to score more again to have a full payment.

Try reading the soccer rules from

You can find it in the rules and you will understand.

I'm not a soccer bettor as well, but from what I understand about the bet you made, the counting or grading is after the bet is placed, not the current score.
I think what that means is, if neither team scores again, you'll get a half win but if only your team scores then you will get a full win.

The cash out option is not your payment if the team doesn't score, it is to give you the option of winning something even if the bet doesn't click with the amount calculated based on the odds of the bet being successful at that time. The cashout amount is lower than the stake at the time, cause the possibility was low already with the time left and chances created in the game.
If you leave it for longer, it will keep going down with the time until it may no longer be available. If the match ends without another goal, you will win nothing.

The grading is based on the full time score and not from when the bet is placed. The option is for the team already with a goal to score over 1.5, which means at least one more goal. If neither team scores again, and you do not cash out, you get nothing.
