Is it possible to win more than one prize in the lottery? Say someone has near 100% of the lottery tickets.
Yes, just read the last page. As you can see, S0lidus won the first and second prize
What prevents someone from buying a very large percentage of the tickets, like 95%, knowing that theres a positive EV thanks to the 1% the casino adds? I guess just the possibility that someone comes later and buys say 10 times as many tickets and steals her money (the EV wouldnt change, but it would make winning more unlikely). Or is there any maximum amount of tickets you can buy?
There's a limit of 10000 tickets per player. Even with EV+, player will still have the possibility to lose all if another player wins with less tickets (unless he would be the only player in the lottery, which never happened
