According to this site, home games are not legal in Illinois: http://www.uspokersites.net/legal/illinois/
If you read Article 28, Section 1 of Illinois’ penal code, it is clear
that any home game, no matter how private, that involves gambling for
real money is illegal. The law actually says: “A person commits
gambling when he plays a game of chance or skill for money or other
things of value.” This restriction doesn’t make any distinction
between games of chance and games of skill, so a private poker game is
illegal in Illinois.
If you do operate a home poker game that uses real-money wagers and
you get caught, you’ll not only be charged with illegal gambling, you
can also face another offense for “operating an illegal gambling
house,” usually a charge applied to the host of the game. There is a
lot of risk associated with playing private poker games in Illinois,
so to avoid trouble with the law, don’t play for real money or any
Unlike some other states, undercover law enforcement officers have
infiltrated private poker games, formed a case, and even confiscated
money, playing cards, and gaming chips from those playing illegal
private home poker games.
This is due to the state law, so any game using real money would be illegal (rake or no rake, fee or no fee).
