I guess that I'm such an amateur in gambling that I've not even considered that there should be sports predicting sites. I always thought that the guess work is personal or with people who have the same interest in gambling. It would really be nice to visit these sites on Google to see how they help in predictions and how accurate their predictions are after a game.
No, this doesn't mean you are an amateur and don't have to use sports prediction site to take into account every bet you make because when the match is clear then of course you can guess with your own ability to make good bet.
But using sports prediction site is also quite helpful for some people who are still not sure about their own predictions, just don't really bet on the results given by the prediction site because it doesn't guarantee anything and only gives you anger or regret if you lose.
You have to learn everything and you need to look at your own predictions with considerations from the prediction site so that what you bet on is not in vain.
True, OP should have been specific with the kind of game that he's into it's gambling, and if he has tried any sites that perhaps didn't give him accurate predictions. Maybe he just needs a site that predicts different types of games, anyways I'm eager to learn with him.
Actually, there are several sites that can provide detailed prediction results, such as the site shared by @Oshosondy and you can try visiting both of them to see how they provide what you need.
But I say again, remember not to rely too much on the results from this site for each of your bets because nothing is guaranteed and cannot continuously provide predictions that can actually result in winning.
