Looks its working as I have tested few rolls, I get tx hash which I can verify on blockchain, just wondering how system picks up those numbers like its the last tx at the time of roll or system grab few tx from the latest transactions and than display result. If bet size is big than system can manipulate the result and only display tx that has last 4 letter against player  

I won't be playing with bigger amount on this one but for small bets I think it will work. OP add autobet feature on your bot...
