Both versions have aka "Poker" in the listing, just to be a little more confusing. I don't mean to be dense...it's a gift
I was very confused by this too. Turns out Sears released Mattel cartridges (yes, the exact same cartridges) with their own box and manual. The white label cartridges are, as you said, the later INTV releases.

You could play them. Supposedly gameplay is harder in one version. You'd probably need both versions though, so you could compare them.
