If the odds of winning a prize in a game are 1 in 4, why don’t I win if I play 4 games in a row or purchase at least 4 tickets in a multi ticket game?

Just like scratch tickets, the odds of winning e-Instant games will vary from game to game. If the odds of winning a prize in an e-Instant game are 1 in 4, that doesn't mean that every fourth ticket purchased will be a winner. 

The winning tickets are randomly distributed; therefore, it is possible to purchase four or more e-Instant tickets without having a winning ticket, just as it is possible to have multiple winning tickets when buying just four tickets.
