I got 1 not-so serious bug and 1 pretty very serious bug , admin told me I should post it here.
1) Max payout sets to 9999x if you enter 0.01 in win chance, which shouldn't be possible as the site automatically blocks payouts bigger than 9900x.
2) THE PRETTY SERIOUS bug: So what this bug does is it gives you a edge over the site, something like the crypto-games' bug(and yup thats the site in my sig.)
The dev should check it and fix it ASAP if they don't want the site to go into negative profit. Here for more details , but I think dev can understand it without me explaining so here it is.
https://bitcointalk.org/index.php?topic=1106133.msg11780956#msg11780956 . I do expect a bounty for this one, as this is a pretty serious bug.
3)(not found by me though, I got to it second) You can bet negative amount as well, which changes the site's total wagered to negative(yup thats me betting -99mill btcs bets).
4) Sub-bug(related to bug number 3): When you bet negative bets, and win/lose, your profile shows it as profit.
