Yeah.
This lottery actually makes "tickets" and then "draws" from them in memory.
You will have 1000/1150 entries in the first round.
If you win the first round, that ticket will be deleted, you will only have 999/1149 to win the second round.
If you win that second round you will have 998/1148 in the third round.
etc...
It's not really technical but there's an overview on the how it works page.
If you have 1000 tickets in a 1150 ticket jackpot there's a fair chance you'll sweep it.
But if you don't get them all, anyone else who takes a prize is going to feel like they won
You could try and get some other ALF high rollers to throw in and grow your pot. But I think you've basically sponsored this one.
You can get about 89.9something % of your money back like this.
