Because that makes no sense at all. In a game of no skill, psychology plays no part. Actual returns approach expected returns over the long run. Offer a +EV no-skill game and quickly go bust.
There must be some site in the existence of the internet that has tried to fight the math and done a +EV game. haha.
actually, +EV games happen in land casinos. Not intended of course, but usually due to some math error combined with game rules/dealer error (and perhaps some unscrupulousness on the players part). There are a lot of APs (advantage players) who try to find these games and take advantage of them before the casinos find out. This was how Phil Ivey won the amount away from the casinos playing baccarat. Edge sorting.
