first person starts with one name. second person goes to nymbler.com and puts in that name and chooses both boys and girls. pick a name from the list that comes up for the next sibling. the third person puts in both names and pick a name from the list that comes up on Nymbler.
EX-
I start with [name]Christian/name
the next person puts in the name [name]Christian[/name] and out of the names that come up picks [name]Brandon[/name]
so now we have [name]Christian[/name] and [name]Brandon[/name]
third person puts in both of the above names and out of the names that come up picks [name]Brooklyn[/name]
so now we have [name]Christian[/name], [name]Brandon[/name], [name]Brooklyn[/name]
each person adds all the previous names until we have seven siblings.
the person after that can start with any name
