When I was exploring the gambling board I saw multiple time this word that people were saying underdog playing. I search it for know more details. But I still confusion, Can anyone explain me it in example in both cases sports and slot games?
The way you constructed this question is a little bit confusing, but let's talk about the main word there "underdog" in sports betting this refers to the weaker team or you can say that it's the team that the odds are not in favour of to win. Underdog playing simply means betting on the weaker side that's what it's all about. Most bettors prefer to bet on the favorites because the chances of winning is high compared to the underdogs
OP only needs to understand what the word means and how it has been used in the gambling context, you all have made a good point explain to him about what it means l, though I presumed he finds it more difficult to get the actual meaning related to gambling, but since everyone here has given the breakdown of what the word means to a lame man language, underdog is a smaller or weaker team playing against a strong one.
