I've never played DFS, so I'm not sure how it all works. But I always thought it was set up like a parlay, where you have to win multiple events, which requires a lot of luck like hitting a jackpot. Is DFS even fluid? or doesn't everyone just pick teams?
It is not fluid, it is static.
There are various game formats though. There are the big tournaments but you can also play heads up, 3 mans, 5 mans, 50/50s (this is a field of like 110 people, top 50 get paid for example)
Everyone gets the same player pool to choose from and you assemble your team based on 50 or 60k of salary. So say it is a Wednesday in the NBA, there are 9 games, you choose your roster from all 9 games.
