Update 29/01/14

• some minor bugfixes
• new website design
• new coin "Leafcoin" added

[Funglekin]

Why even have a limit and not a space for "investors" to make a tad for themselves? Also there is nowhere talking about how the number is generated. This just screams scam to me.

[nmkr]

the limits are because we start with a small amount and increase it within time (2x times already), if you wanna invest you find contact details below.. some infos about the "Algorithm" coming these days with an bigger website update.

[Funglekin]

By investment I meant the way doge-dice or their affiliates have it right there open for all to see. Also you should place notes on the site about increasing the max bet, or make it dynamic based upon how much you can cover. Also there is absolutely no need for you to be taking % of an over or under bet and not just the transaction fee.

[nmkr]

we currently working on a few new things. within the next week it should be ready and we update this post also, currently testing a new coin..
with the layout changes there coming all needed infos too .. its just a beta phase right know and all worked good last month..

about the transfer penalty you are right, we remove that in the next version.

[Funglekin]

Glad to help, hope you succeed.

This appeared to be working fine, with deposit and withdrawal being pretty instantaneous, when a single gameid (105459) did not return its payout.

nmkr can you do anything about this? Otherwise it's pretty suspicious that the largest bet mysteriously doesn't have a payout, whilst all the smaller surrounding ones are find.

Aside from that, it seems to run pretty smoothly.

Okay, now cut the crap and give us the real winning probabilities. Because it's obviously not 50/50.

Not provably fair?
Good luck with that.

Not provably fair?
Good luck with that.

This , also with a huge increase of betting websites popping , there are sure lots of scams around too.

[Mivexil]

Heh... Started winning (and I mean winning hard, like every 5 bets I'd be one ahead), insta-maintenance.

Guess they mixed up their unfairness adjustment...

[GTminer]

It appears to be a scam with near mathematical certainty.
First off the math.
Im assuming 0 is not a valid number so high or low same 49.99% chance. (There are 4999 number from 50.02 to 100.00 inclusive, and 4999 number from 0.01 to 49.99)
So a win is double your money, and a lose gets you 10% back.
For a 1000 unit bet you get on average 2000*(.4999)+ 100*(.4999) = 1049.79 (this is your expected value, feel free to verify math)
OK, so were talking like blackjack odds if you're the house, you're guaranteed to win given sufficient bankroll and long enough time betting. (the house always wins, they can cover the loses the allow the casino to be open to bets long enough to let the variance (the ups and downs) cancel out)

So the next step is just to try it. So I got 1mil leaf and placed 10k bets as rapidly as i could. I should have kept track of all the numbers, didnt know you can only see 1 page worth of betting history. For the page I can see, I had 9 wins and 21 loses. Now you can flip a coin 100 times heads in a row, just whats the odds. So using a binomial probability calculator, there is a 99.1% chance one would have 9 or better wins given a 49.99% change to win and 30 trials.
Basically, yeah, its not provably fair, because it does not appear to be fair.
All in all i lost about 400k of the 1 mil (im not worried about the loss, it was a "fun" experiemnt, it was mined anyway, and you can never bet something you cant afford losing)
By looking at wallet transactions, I have 7 wins and 47 losses. Approx probability for these stats and the site be fair 0.0000000001
The odds of having that many losses given a near 50/50 is staggering to the point of plausibly impossible. So scam.
And really, what retards setup a betting scheme where they are mathematically going to lose 4.9%, its just a de facto faucet at that point.

tldr: Yes, it is a scam, do the math, try it, but please use minimum bet to convince yourself.

edit: CoinsFortress go F yourself for free! I looked at my wallet transactions and found that i bet 93 times and only have 7 win payments and 47 loss payments, so they owe me at least 40k leaf for the other 2 i know i won, just on the page i can see, and at least another 40k for the losses. So even if the rolls are fair (they are not) its still a scam since they cant even payout correctly.

My LEAF address in case I helped you not fall for this, or if lol CF wants to give me what they owe me lol.
