Im sorry I was mistaken I guess. I was sure you could use multiple codes multiple times and still recieve rewards but i guess you cant. I was mistaken and apologizefor my rude reply earlier I just thought you were another obnoxious player who will say anything to get people to use their code.

I know you asked this 2 months ago but hopefully Im somewhat useful. You redeem peoples codes by entering them into the invite section under settings. Click on your avitar (the upper left hand side of the screen) then click on the settings tab (the very bottom right hand side of the screen it looks like two gears) once there click on the invite tab (3rd column second row looks like two avis one behind the other and a plus sign) then once you click on that just switch to the "Claim" tab (upper left hand side of the screen) click on "change (or claim not sure what it is the first time you do it) ivitation code" put in the code and viola youll recieve a reward for activating it.

It's not true you only recieve rewards for the first code you use. Each time you claim a code you recieve its rewards regardless of how many other codes you've used or how often you've used the same code. I know because I've claimed several different codes on several different accounts. Stop trying to spread misinformation so you can get fat off of others purchases. It's dishonest and annoying.

Yeah but you've failed to mention the prize stays the same regardless of who uses it or how much it's used. For example I believe my code gives its user 3 1-hour reductions and I believe a little grain (it's been a while since anyones used it so I can't remember). No matter who uses it or how often they use it/it's used the person will get 3 1-hour reductions and a little grain. In other words while it's true you can't choose what prize someone gets for using your code you can in fact tell them what they will recieve by using it. Just a tip for anyone who reads this comment. Don't let anyone fool you they know exactly what their code gives so if you use it and they've promised you something you don't recieve they lied to and cheated you.
