Spinner Card dimensionals question

[Crystallight]

I bought some dimensionals at Michaels to do a spinner card but noticed the ones shown in the instructions on this site are different. Mine are circles where as the ones shown in the example are shaped like a hexagon. Does that make a difference or do I need the hexagon shape to make it spin right?

I just made some spinner cards using pop dots, which are round, and they seem to work just fine. As far as I can see as long as the top layer is far enough away from the second layer-the pennies can move.

Good Luck!!!
