Royale player count

I notice the other game started with only 40 people, sin what is the minimum amount of people that have to be enrolled for it to start off? What triggers the game to start, is there a timer once x amount of players join? I remember before it the game’s launch you mentioned there could be more players in a game started(up to 100 I believe), is that something that will still end up happening if there’s just a ton of people joining a filling game? Or maybe when the enrolment is eventually raffle based the amount of people with tickets is what will determine how many players will be in & if there’s another game that opens up for more people enrolled? Sorry I know it’s a lot of questions I’m just very curious on the mechanics for enrolment & how it’s meant to eventually run.
