I don't believe there could be a 100% guaranteed game but yet my friends who are eager to make profits in the gambling accepted to play the gamed as instructed and at the end of it, they all loosed the game and at then, the rest of us were happy because we didn't play the game else we would had loosed as others.
I want to ask, do you believe in experts gambling predictions?
Prediction in gambling is an attempt to predict the outcome of a match or game, so it is clear that prediction cannot be completely 100 percent correct. The results of a match or game cannot be predicted with certainty, so do not believe too much if someone directs you because of their prediction. Maybe if in a match there is match fixing or there is a bookie who directs which team will win, I can believe it and the possibility of it being true could be 100 percent. But I think this will be very rare because they definitely prefer to make a profit.
