Here&#x27;s the simplest explanation.  Neither should be illegal, they made a law that explicitly banned one and not the other.<p>Also there&#x27;s fundamentally a difference between playing against other players and playing against the house.  If the professionals on draft kings &#x2F; fan duels got to play the house in a similar setup it would be even worse for the people playing for fun.<p>Why are people allowed to go to the movies?  In New York a movie ticket is $15 and 90% of the movies are, in my opinion, absolute crap.  So that&#x27;s $15 with a 10% chance of getting your moneys worth and a 90% chance of losing all of it and 2 hours your time!<p>I think the one reason why it&#x27;s different for the leagues is that daily fantasy doesn&#x27;t really create as large of incentives to throw games or rig games as much from the refs or players point of view (not that it&#x27;s common, but it&#x27;s definitely happened in the past).
