I payed extra to get it fully working.
There are extra things added like contest and jackpots (it goes all automatic)
Jackpot you can choose for your own (the iphone contest is still @ my part to complete so that i will do i have the phone on stock thats why i gived this promotion)
House edge you can choose (a normal slots take around 15%) this one is set at 1% now to build a good player base.
bets you can see live how many so you can check that.
provable fair can be set on to but that cost some extra btc cause it needs to be writen just like the jackpot and the contests..
For now i put more off my own money into the jackpot but thats because i wanted to attract more players. what worked..
