The block in which the above post is included has a merkle root of 21c593a65ae1c6ab82fb5b5f7484690d84307120.
The last two digits of this root are used to determine if there is a winner. Ending in 0 gives an upvote and ending in 00 means the jackpot was cracked. The remaining digits determine which ticket wins. To do this we compute the residual after dividing the root by the number of virtual tickets. In this case this would be:
21c593a65ae1c6ab82fb5b5f7484690d843071 = 753135954511738010195645601569723314275102833 in base 10. The residual after dividing by the number of shares (924) is 245. Therefore ticket number 245 would win.

Because the last digit of the merkle root is 0, we have a winner. The winner determined by the merkle root is: steem-jackpot.
In order to find the winner we have removed the last 2 digits of the root. Congratulations to the winner, you got an upvote! The jackpot was not cracked.
