114023 Not sure what to call this

I have 16 domain names that will use the same script. A casino slot machine web, but it will be free play. But members will have to sign up for a account. I do nt know what would be the best way to explane this job. I know that it chould be some slots, and maybe som other games as well. I am open for thoughts. I will have the winner up load the script to each one of the domain name each week.
