Here's a thing that it might work. If you gamble in the 7th of every month (like say November 7, December 7, etc) you might get lucky and hit the jackpot. The lucky seven will sure bring you some profit.

But seriously though, I think there is no strategy at all. You will always lose profit, because that is the way gambling works. I bet that if you make a gambling/dice site you will earn a steady amount of income.

Lol, for me everyday is my lucky day. Even for all people, i think every single second is their lucky time. They just not understand about luck.
Because we create that luck.
Gambling is pure on luck, but 'luck' in here is stand for life. Not for game of gambling.
When it goes to gambling, is all about random.. your probability is 90% lose 10% win.
You can win at gambling, because your probability is 10% win. But when you keep on going on gamble, you will get "randomness lose".
It's not your bad luck, on gambling you will always got that probability. Especially on Dice game.
