Let's verify yesterday's drawing, the game of 2016-07-19.

First, you need the first block that has been mined on 2016-07-20, which is the block #421477

The hash of this block is 0000000000000000050ae5575d800bffc7d73c0399187a2812b1183690cdbc00
the 16 last characters of the bloc are: 12b1183690cdbc00

Then you need the sum of the values of the transactions: 0.34642218BTC = 34642218 satoshis.
Note that the value of the jackpot is 1% less than the sum of the values of the transactions, this is our margin.

In order to manipulate the figures, I transform 34642218 into hexadecimal: Ox210992A
I can now use the calculator (mode programming), in order to perform the modulo: 12b1183690cdbc00 % 210992A = E0ECBC
this makes 14740668 (in base 10) + 1 => 14740669 = ranseed

Now let's look at the transactions, ordered by the player address:

PlayerAddress	\|	Game Value	\|	Cumulative Value	\|	Is More than seed?	\|
16eNR9db9UsuE3afTcZsjiWqWk5NbUtJYV	\|	329127	\|	329127	\|	0	\|
1BXVDjiWQCX9oFaLBxk6djirtrXFwLk5Bc	\|	22304169	\|	22633296	\|	1	\|
1GfXepAbYXsiATy6hAe4V8QKJfGFtDwTEU	\|	1191718	\|	23825014	\|	1	\|
1GkKcNLTkF3fxRqYYxVEgDsTBy9wi19fGy	\|	742799	\|	24567813	\|	1	\|
1LzEG4c9MiqD6qkjuu6pUBhLYoEicmLv1s	\|	74405	\|	24642218	\|	1	\|
1Np3mwWYnPxH5g6Hj3SQ1RN6JX3WZdavj5	\|	10000000	\|	34642218	\|	1	\|

On the second line, the cumulative value of games is exceeding the value of the seed: the winner is 1BXVDjiWQCX9oFaLBxk6djirtrXFwLk5Bc

May I demonstrate it again with the game of the 26th of July.

Block number is #422404 and the last 16 characters are: 32e1fc32bef75ea8

Transactions sum is: 77949241 (in hex: 4A56939)

Rand seed is: (32e1fc32bef75ea8 % 4A56939) + 1 = 4A3AEFD (in decimal: 77836029)
