if that is a genuine gambling game and you wanted to have players on it why are you going to attach ponzi to it? ponzi is a fraud investment scam i really don't any user would transfer anything to your ponzi game.
It's not genuine games it's Ponzi that's why it has its name Ponzi, he just assumed that it is the same as gambling your money which is actually you give it to him .
How does work you need to deposit doge and you need to wait for other risktaker to invest the same amount before you can get the 50% profit. If there is no investment after you ,you will not receive anything in exchange for your investment. And one more thing 50% of the investment willk go straight to their pocket.
