The next drawing for the btcLottery should be sometime tonight (tuesday night)! Last week we had no winners in any of the games, so all games are in Round 2 with all the bitcoin still up for grabs!
The drawing's target blocks (the blocks we pull the winning numbers from) are 126501 through 126505. So you must get your bets in before block 126491 for your bet to count towards the drawing. Any bets made after block 126491 will be returned to the bettor.
