Back then when I was very active in sports betting, I thought about this, that I should be able to bet several options in one match. Take for instance, Liverpool vs Manchester city, we could have this builder;
Liverpool 1x
Over 2.5
BTTS
And that would have been a terrible idea since in the last four matches the score was twice 1-1 and 2-0, so you would have had a lot of time with over 2.5, you would have half lost half the time with BTTS,

Also, one bet will not be counted as
- Liverpool winning means at least one more goal than Manchester
- BTTS means Manchester must score, so Liverpool will have to score at least twice, 1+2 > 2.5
An over 2.5 bet here is useless
Very true, I selected two options that are like one.
I just made it up, but when betting, we can will have to analyze carefully and this has shown that bet builders are also not easy to win unlike as I thought. In fact, there is no easy win option in gambling. Every thing is risk, although some options are riskier.
