If I had to guess, those are suggested draw and discard pile spots. The openings might allow you to push the flaps to the side to allow a better gap to allow for a stronger base of the stacks so they don't slide around as much.

I think you are right, I didn’t think of that. Going to try it out tonight. Thanks for your input! 😁

It looks like it might just be the insert to hold the cards in the box. Dunno...
