may I ask whats the use of the daily million tourney prize?
You mean the tickets you can win in the satellites and in the freeroll for tickets?
Tickets for the daily 1 million guaranteed tourneys (2 of them a day, shows in red in the lobby) you can win in the Daily Million Satellite and in the Daily Million Freeroll.
The buy-in for the 1 million guaranteed tourneys is 1 ticket or 15k, when you have tickets it automatically takes the ticket for the buy-in.
