If anybody was interested in how winnings are paid, this is the transaction from when Round 2 was drawn.

The key thing to notice is that the round was drawn by an anonymous player (TQB1tr...), and the winnings were paid in the same block that the winners were drawn.

Side note; the player that performed the draw claimed winnings of 2% of the prize pool.
