While sports betting has been legal in Illinois for a year or two, other than a very brief period you couldn't sign up on-line but instead had to go to a brick and mortar.

Last week, it finally became legal to sign up on-line and the offers are flying.

One offer from Caesars is if you lose your first bet up to $1,100, they will reimburse. Fan Duel has the same for $1,000.

My initial thought is sign up for both and bet opposite sides. Any suggestions or thoughts as to a better approach?
