Any tricks available in gambling to won the bet?
Not sure what you mean by any tricks to win a bet. To me it depends on the game and also depends upon the strategy that you use. For example, playing roulette sometimes you can make decent money with the Martingale system, but it is not guaranteed and it is not a trick. Do you legitimately when when you're gambling there are no tricks, you can only use the information you've learned to make better decisions.
I think people use tricks to win the bet while gambling, because without these tricks wining money is not so easy and the people who do not use any trick or do not know any gambling trick he never wins. Only the experts of gambling win the bet because of the techniques and the tricks they use while gambling. I will suggest all the gamblers not to gamble if they do not have any tricks learnt about gambling.
