Golden Chips promotions will have specified online table games they are eligible to be used on so it is best to always refer to the Terms And Conditions of a given promotion to see what online table games your Golden Chips are eligible to be used on. The Golden Chips will be in the same section as your other chips.
Once you know what games your Golden Chips are eligible on you simply have to login and navigate to an eligible game where you will be able to play your Golden Chips.
Note: You can only use One Golden Chip per round/hand.
