I do not know if I should ask this in here!
I have designed a board game that is more exciting than other board games.
Where can I find retailers who can convey it commercially?
Do I have to register it first?
Thanks

First off. Do you have a patent ? Have you done a test with someone you don't even know seeing if they like it or would play it ? Trying to get big stores (like toys'r'us/walmart) would be hard, and might even cost money (I don't know) local toy shops might be a good start until you can get some positive feedback.

P.S if you don't have it patented a big company can take your idea, and you can't do anything.
