how can you know the name of the winner ? there is no command to enter a name !
After it starts there is form where you can put your btc address and if you win you will get paid to it.
Who won the last puzzle ? Bitcointalk username of the winner of last puzzle ? Basically, you don't need to create new threads.
Critically, This is not provably fair game (The username of the winner is yet not known)
P.S. Ironically, watch mode activated.
Maybe he just didn't have account?
