Do you have metamask?
It's a smart contract and there are no back-doors written in or anything so it can't be manipulated (as far as I can tell. I'm no expert on smart contracts but I couldn't find any malicious code.)
The site details the whole game and how it works.
I treat it as a fun gamble to earn passive income.
Has been paying out so far but there are no guarentees.
I have nothing to do with the contract other than I've been playing it.
Posting it because you get 5% referal fees for people that sign up with your link.
They do this so the marketing for the game is handled by the players, as they have an incentive to get new players to join.
Something to watch every day.
Like anything though, I wouldn't invest money I wasn't comfortable with possibly losing because things like these are unprecedented.
