Wasn't gaming basically synonymous with gambling at that time though?
I think gaming as a recreation without gambling didnt really come about until the 1940s - 1950s, right? Commonly, of course.
EDIT: Also of important note, in 1638 the Puritans in the US state of Massachusetts (colonial at the time) enacted a law that made gambling illegal. It outlawed ownership of everything gaming related from dice to cards, and citizens were not allowed to even play in their own home.
