Any tricks available in gambling to won the bet?
If you're talking about online casino games, probably not. There is not mathematical way to win these bets. But you can make the best possible mathematical decisions. You'll still come out on the losing side in the long-term though.
Not only in online casinos, tricks are not present in real casinos for gambling also because gambling is purely a luck dependent thing and if you are lucky enough, you would definitely win the game and if the case is opposite, you would return empty handed with regrets at your side. Some people think that math can help gamblers to win the game which they are losing because calculation will allow them to make the correct guesses but in reality it is nothing except a blunder.
