Pick one of the available Tickets from the table above. Post a reply with your pick + the txID of your transaction.
Once all Tickets are taken (and paid for) I will select 1 future mined blocks that will determine the winners.
The last character in the hash of that block will decide who has the winning Ticket.
This gives you 16-slots. ^
The following thread is an example of turning the same idea into a 64-slot raffle with 3-winners: https://bitcointalksearch.org/topic/rafflesatori-madness-85-prepost-fork-50x-pre-for-1st-ception-inside-064-5129234
You can expand it further if you have more participants. As long as you pick a future block, nobody will know the outcome and everyone can find out the winner simultaneously and live - without any middleman, interference or trust required.
Check your PM please.
