I wonder why people still post things like this even though it's definitely not legit. I don't think someone will play this game plus the site is poorly constructed and no other information shown in there so it's likely to be a ponzi scheme type of site just mentioned earlier.
Yeah true just looking at the website you could already tell that this is a not legit website. The website doesn't even have an account system that is connected to the software are they we're inviting users to participate with an initial cost of 0.002 ETH which is completely crazy. Yet they are assuring users using a etherscan source code in the etherscan website. Probably you would just end up losing the game the algorithms in a lottery game could easily be manipulated, I'm a programmer myself and I could easily do this is a probability winning game.
