I always get paid by this site but why I say is it's a scam is because they quote to be "provably fair" but there is an algorithm in the back which makes you lose.
I've chosen the 47.25% chance of winning and losing 50+ times in a row doesn't make sense what so ever when that's the percentage chance of winning, which isn't mathematically possible. This tends to happen when you bet higher amounts, play for more than 20min, or happen to keep the page open for a few hours(noticed this when I slept with it open overnight once).
The site can be fair and gives a chance of winning but when you try to make a "real" profit it forces you to lose.
I also notice the "lottery" winnings tend to go to the same people, when you watch the lottery page the user ids they display who win; end up winning every lottery, every other, every 3 to 4 - occasionally more; it will vary.
Just a little hint, clearing cookies helps you "win" again but they also keep a record of how you bet in the background, clearing cookies and cache; I tend to change to a freshly newly installed browser with no records in it - it catches on to you playing earlier. Don't fall for people telling you to clear sessions/cookies to trick the site to letting you win again, it doesn't work.
I love the site but it's defiantly not "provably fair".
Basically if you want to win on this site play the high to low game very safely and not frequently, maybe you can make a profit after a few weeks to a month(aka $100 or more USD).
I bet 50 times minimum amount to control scam or not... When i bet low and lost, then i clicked high and lost again. Then i bet low and failed again.. Hi-Low-hi-low-hi-low... 50 times repeatedly... Always lost...100 percent failure...
