Is the roll fair?
Winning number is given by combination of Server Secret and Bitcoin Block Hash at given height.
While using Blockchain data ensures that nobody (not even us) knows the winning number in advance.
Server Secret ensures that bitcoin miners can't abuse this system (by selectively publishing block with hash which is in their favor).
Active round (the one users predictions are valid for) is higher than the current highest bitcoin block.
Which means that if the current highest block is 800,000 our users are predicting number for round 5 blocks above ( 800,005 ).
We are also waiting two block confirmations before publishing relevant Server Secret and final announcing winners.

How to validate Roll ?
Example_Case: Round 833085
1 - Create string: Block-Secret-Block-BlockHash2 - Use sha256 tool: Template or see Example_Case
3 - Convert last four characters 0d34 into DecimalHex Dec Converter or see Example_Case
0d34 = 3380
WINNING ROLL 3380
