I want to join too, but I can't because I have no idea how it works. Is there like a topic about all of this that explains what this is all about that would allow us to get it? I do not even know the reward though, like is it a big reward? If it is something small then maybe I wouldn't even care but if it is big enough, I keep seeing it all the time and have no idea, would love to join.
That's a code that you can use to claim free spins, dont take a look at the image but focus on the word under that bitcoin logo.
Afaik that's the code for the free spins, just guessing based on some previous posts related to this free spins giveaway.
In very simply explanation, log in to your FJ account and find the bonus page where you can put a code then claim it.
I think it's quite simple, enter the code and play after completing the free spins, then claim activation and the balance will be credited to the main balance.
About big prizes or not it depends on our luck, but I've tried several times to play in the code is quite fun.
