Hi Corey.
Double prize pool works just like a regular tournament. There is no change in the way the game is played, and the double prize poll has no effect on the strategical way you would play.
You can pay either e.g 100$ or 500$.
Lets say theres 20 players and the payout is 50/30/20%, and 10 players have paid 500$, the rest just 100$.
All payers can win from the main pot (20x100$)
Winner will win 1.000$, 2.=600$, 3.=400$ -> This can be won bu all players.
The payout from the double prize pool will then be:
(10x400$) 1.=2.000$, 2.=1200$, 3.=800$ -> This can only be won from a person who have paid 500$.
If your final position is 4. place (and you paid 500$), but none in the first 3 positions have paid 500$, you would win 2.000$.
But if you win (and you paid 500$) you'll get 3.000$.

About the buy-in screen. I Just meant, it would be really easy if there just where some columns (player name and e.g. buy in/bounty/house contribution/double prize pool) where i can just check them with a "√", and of course a add-player button.
