Free poker leagues in Illinois question

[rayxtwo]

I run a free Texas Holdem' league in St. Louis, and I was trying to find the exact laws that say my type of game in Illinois is illegal. I have about a dozen players that come across the river to play in my games in Missouri, and they tell me that I could have about three or four bars running games over there if it was legal.

My tournaments are free, with no buy-in money required, no purchase requirements, (you don't have to buy a beer or something to eat to play), and I strictly prohibit any cash on the table, even if it's to pay for a drink that's been ordered. The bars pay me for running the game and pay me just like they would be hiring a band to play. Out of that money, I pay for any prizes won by the players.

The St. Clair County Procuting Attorney told me even if it's free, it's still gambiling. I think this is a bunch of crock. I'm looking for some help in finding the law where they come line of B.S.

Thanks for your help,

Ray
