My cousin used to be an ex moderator on the habbo website and helped create the rooms for events. They gave him a code to allow him to get the credits through to his accounts for free so he could make the rooms without paying.

Now that he left habbo, he told me the code and this is it: 19399609

For you to get the free credits like I do, call this free phone number from habbo:

0906 900 9100

Once you’ve rang the number, they will ask for the code and then you put in the code to gain 45 free credits. Then after 10 mins after you’ve rang, go onto your account and go into one of your rooms. Then in the speech bar enter :credits19399609

[You may have to reload habbo for them to appear in your purse]

Habbo will then give you the 45 free credits, and this number can be rang over and over again for as many credits as you want. I believe this is the only trick in the book that actually works and comes out in good fortune.
