If you try to sign up for the online Full Tilt poker room you will generally find that the site asks you for a Full Tilt referral code. If you are unsure about what this referral code is then you should simply enter the word “FULLTILT123″ in the required box. However, there are quite a few different referral codes that are applicable for the Full Tilt poker site and so as long as you know of a valid referral code you will not have any difficulties.
