As of now we don't have such code so if you want to add something, you can place your request or your personal coupon so we can use it and let us both be blessed with free items.
We really need such gifts because the game orientation is focus on spending Clams. Well this is premium currency that you will usually earn from spending real cash. There are lots of complaints about this game as too greedy to push everything in spending Clams especially with Circus. Now hoping for promotional and referral code we can have free Clams or else it is time to break with downloading Family Guy The Quest for Stuff Cheats as the last resort.
Think about, not all players can spend money for the sake of entertainment. We love playing iOS and Android games because we can get it for free but with money involvement, we need alternatives too.
