Why is it that wagering contests are usually on games with a house edge and not on sports betting?
I’ve seen a few contests where you need to reach a certain wager amount to qualify, and sometimes the player with the highest total wagers wins by the end of a set date and time. But it’s almost always on slots or other casino games with a house edge, not on sports. Any reason why that’s the case?
I think it's fair for them, first it is fast paced game and you can easily wager easily compared to sports betting, second thing all of the games are games of chance and you can't analyze it to increase your chance of winning and lastly it's for their own good, the more you play in the slots/provably fair games the more they are winning since they have house edge, so in short it's a win win for them.
They would earn because many people will try to wager, the more people will be losing and they will earn from house edge.
