Interesting concept, however 1.9% house edge is relatively high, compared to other sites. I'm interested in playing, however. I'm kind of sick of dice. Currently i'm hooked on bustabit 
The server's down!
Honestly I don't know how exactly House Edge works in multiplayer game? You fight with players and yet you pay fee or something?The server's down!
And yes, site is down right now: "www.weclick.io Host Error" - Not exactly the best start for a new service.
Yes you will have to pay a fee out of your winnings so the site can make money. You will pay 1.9% But this does not change your odds it only changes your reward. You still have odds against other players and not against the house. The house only takes a fee for putting the game all together and facilitating it.
