When the effect on player expectation is positive, you’ll make more money, when
it’s negative, you’ll make less. Most land-based casinos use a fairly standard
set of rules, but they can always throw something different in without mentioning
it. The same goes for online blackjack free games, though you have every right to ask
detailed questions ahead of time before playing online, whereas the same lines
of questioning may gain you unwanted attention in Las Vegas.
