With all form of gambling there is need of luck. Only with luck it is possible to make a good winning. Strategies give hands, but it won't sustain. I was in frustration from tow to head, because just after the week's payment got credited it got washed off. This means I'm unlucky, if I were lucky now I could've got my payments multiplied. I tried a different strategy, placing bets over/under 75/25, the small fund in my wallet made me loss everything.
Luck is something that every gambler must have, no matter what gambling game they play. Without luck, we will find it difficult to win some money and most likely lose. Strategy is a way that helps us to win a game and to complete it, we need luck. If you play dice, you need luck because the game is based on luck. If you do not have it, you will not be able to win it and will lose. I always play with small money that I can use a certain amount to play within a certain time. I also try not to place too big a bet because the risk of losing it will also be big.
