I tried out something while I was watching some games in the ongoing Olympics and this is what I did;
I looked out for sports I wasn't conversant with the athletes and didn't know who was better at the sports and did a random prediction on the outcome of the game. I did it for swimming competition and some random boxing yesterday and out of up to 7 predictions I made, almost 6 went the way I predicted it.
It reminds me of writing an objective examination in high school and when you're done with the questions you're certain of, and you just do some random selections and luck could shine on you and you get up to 70% from your rough prediction.
I have not tried this in real games that involves using money but would want to know if anyone has ever tried it before.
Have you ever placed a bet by just doing random guesses on the outcome of the game?
In your case you know less about these games, you just decide to give a try and things turned out well for you, this is pure act of gamble and you got lucky, if you think otherwise you can decide to give a try again and I can bet with you that things won't turn out the same.
Some people like you choose games that they are very good at and things went bad for them, see, from now on it will be better to accept that you are just lucky whenever you predict and things work your way, there is nothing special about you, don't start feeling yourself as a special kind you are nothing but human like the rest of us.
It is better you stick to risking what you can afford to lose or else you will likely end up regretting your decision, gambling is still gambling, an act of predicting the future and that my friend isn't withing the capabilities of any human.
