The Canyon Casino will give anyone a free $5 Millienium chip for free. Black Hawk, Colorado. All you have to do is get 2000 points at the blackjack table. It seems that is 4 hours of play. Did you need 4 or 5 chips? They will be offered from Jan 24 through Feb 24. Only in Colorado, right?
The Colorado Central Station hasn't let anyone know how they will release theirs. A token will also be available, somehow. But no release yet.
