It's totally a scam. They have real legit odds your first 10 rolls but if you're using a double up strategy (have a base bet and keep betting high/low repeatedly doubling your bet until you win then start with base bet again) it works just like roulette odds black/red in the casino where you should win by the fourth or 5th time of placing bets on the same color. However I tried this three times in a row with the free give out. The first 10 rolls will work like the odds should then after the site notices you're winning more BTC than you lose it suddenly rigs the game to land somewhere not in your bet until you run out of BTC. I literally lost 5 and 6 times in a row each time betting on the same side and lost that many times in a row. No fucking way, the odds of that are ~(1/2)^n [the actual base would be more like .525 rather than .5 because they have a 5% advantage] where "n" is the number of times a coin lands on the same side in a row (or in our example numbers that are higher or lower than 5000 where each represents a side of a coin) where getting n=5 times of landing on the opposite side is less than 3% likely and n=6 turns is under 2% and it happened every single time I've played the game after my free satoshi and then when I decided to test it three hours in a row it happened three times in a row where each time it was under 3% likelihood so 3%*3%*3% = .0027% maximum probability of these three attempts ending with 5 or more times of the wheel hitting low or high in a row. On other attempts I alternated and somehow again it would end up with me taking a loss that many times in a row. It's crazy. If you use that site for free BTC don't make more than a couple bets because after you play so many bets with honest odds it gets rigged against you. Just collect the free BTC if you want to keep it. They must be making a killing. The odds should be close to roulette and blackjack (assuming unadvantaged players) and I've spent 3 hours in the casino playing blackjack and came out doubling my money before multiple times using the same betting scheme I did on this site.

I'm only making this conclusion after thoroughly testing it for myself. It's very believable to me they would set it up where it will be honest for the first few turns to get gambling addicts hooked and then switch rig the game after so many turns so people don't really keep their 72 satoshi and end up wasting time visiting that site because they always lose their money. I actually programmed a simulator in java to see if I could reproduce that in a simulation using my strategy and about 48% of the time I won like I should have and had zero times of the numbers being high or low 6 times in a row after 1000 games were simulated, though there were a couple 3-peats and 4-peats. Just thought I'd make others aware to avoid the frustration I had trying out different faucets.

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).
