Single bet always had the high probability of winning but it will require you to stake very high since there odds are usually small sometimes if you don't have enough cash in your balance you will stake and have very little cash out that's why you need to combine multiple bets to at least boost your odds to have a good pay out, what I noticed again is that having small odd doesn't really matter what counts is consistency inasmuch as you have a small odd you can keep gambling go increase your balance but sometimes it doesn't work that way we may plan it.
