Here's the relevant way to enter without having a code:
Text-Message: Text either “dance” for the Lipton Iced Tea prize pool or “game” for the Brisk prize pool to short code “87963". You will then be sent a follow up text message requesting you to reply with your email address. You must reply with your email address to receive one (1) Game Play. After your reply to the follow up message is received, you will be sent another text message identifying whether you are a potential Instant Prize Winner or not.
Limit five (5) Game Plays/Sweepstakes entries per Participant per day regardless of the method entry used to enter the Promotion. Limit one (1) Game Play per Code.
FYI: I got a promo code emailed to me for some gears DLC (they are sending out 500k of them) but according to the email it won't work until March 19th so hold onto the email - edit: The code works now.
