You can win the Jackpot if your dice bet meets ALL of the following criteria:
Your dice result is either 7.777 or 77.777
Your dice bet is a winning roll
Your bet amount and profit both are at least 0.0000015 BTC, 0.00045 ETH, 0.0015 LTC, 15 DOGE, 0.0015 XMR, 0.00015 BCH, 0.0045 ETC, 0.00075 DASH, 0.0225 GAS, 4,850 PlayMoney
The last two digits of your Server seed + client seed combined and encrypted in SHA512 are 77 (called the jackpot number)
For the Jackpot number, the calculation goes as following:
It's basically done the same way bet results are calculated, but in this case take the two characters at the end of the SHA512-hash. So first you need the SHA512-hash, this is your Server seed and Client seed combined and encrypted in SHA512.
As the next step, take the last two characters of your SHA512 hash and convert them from Hexadecimal to Decimal. If this number has 3 digits and is less than 200, use modulo 100 to get a number between 0-99. If the generated Decimal value is 200 or higher, repeat the last step with the next 2 characters of your SHA512-hash from right to left. Continue until a number between 0-99 is generated.
You will receive 100% of the Jackpot if win amount is above 0.004 BTC, 2 DASH, 40000 DOGE, 1.2 ETH, 4 XMR, 0.4 BCH, 4 LTC, 60 GAS, 12 ETC or 24,250,000 PlayMoney. If win amounts is lower, you will receive a proportional share of the Jackpot with the minimum set to 1%. Jackpot is given to you automatically, you don't have to report it anywhere.
