If you talk about natural numbers rather than integers then 0 would be odd. But since some people would call that cheese I have other versions that have opted out from using 0 cost cards.

Has anyone addressed whether flipping a 0 cost card when gambling with the goblins counts as an odd or even? I'm torn on that one. I can see it being "not odd", as well as "not even", but not really either.

If you talk about natural numbers, zero wouldn't be neither odd nor even, because zero is not a natural number.

Take a look at my version:

That X equals 0 is in the FAQ. That 0 is an odd number is maths.

Really? Here is says 0 is even. This came up in a game once, that's why I'm even thinking about it, not trying to disrupt your comments section :)

Take a look at "Examples of even numbers"

X counts as 0 and 0 is an odd number since an even number is defined as a number divisible by 2.

Cool. Is this in the FAQ somewhere? Thanks for the response.

And also, what about X cost cards, which I presume would cost "nil"?

If it's not odd, then it falls under "fail" category.

0 is even number. It's integer number, and after division by 2 it's still integer. "0 / 2 = 0" <- this is perfectly ok.
