This is not gambling, I don't have the exact word to use but this is too much greed, have thought the possible outcomes from that games. If you select option of win, there is likely draw or lose to happen and this is not something you can control as far as sport gambling is concern, you will only lose more than you will gain even though you are staking with small money, when you combine that small money together, it becomes big money.
I think 10 selection is okay at most, then increase your staking power a little and you are good to go for the games and hop for the best outcomes.
