at the real lottery the chance is one to some million. And if they only sell a few hundreds of tickets the chance would be 1 to a few hundreds.
I heard about some lottery system for real estates.
First of all, would you mind to tell us how did you find this site? No offenses but I doubt you found it, because I think you are the man behind the site.
Second, if you are not the one behind the site then I do even sure that you knows about how lottery works. If you found it, I'm sure you are a lottery lover. It is very rare for non lottery lovers will find a lottery game then share it to others.
Third, even if the chance is bigger than some other lotteries but without clear explanation on how they choose the winners. It should not be a good reason to join a new "poor" lottery site.
Last one, no need to convince us to join this lottery. No one will be interested, trust me.
