if there's a minor change in names on accounts, (for instance, John David Doe, J. David Doe, JD Doe) sometimes it works. Other times, they'll flag it and deliver to only one. As I recall, some people have even complained of having accounts closed.
If you have various accounts with the same broker, but each is titled differently, either all the accounts get them or none get them - or at least that has been my experience.
I started playing them about 4-5 years ago after hearing about these "lottery plays" on the radio on Stocktalklive. Everyone in the chat there played them in multiple accounts.
