I did try the demo version but it seems that something went wrong, I tried it with 1.14 payout with max bet, it said there is 1 and I assume that it is 1 btc but when I hit 3 eyes the payout is suppose to be 0.14 but instead on 0.14 the number does have really long zero, it is like 0.0000000014. This is what I get about after tested it, may be you should tell us something good here or there will be no players instead
I think you have bet 1 BID (not btc) or 100 satoshi, and thats where the long zero comes! And i must say that ur win ratio will raise if u find the more unlikely number of eyes, through ur number of choices. For example, if u choose 30 blocks and dont find any eyes, u win lots of BTC
