Quoted from atrainn:I have hardwood floors in my basement and use these on all of my games: https://www.homedepot.com/p/Everbilt-2-1-2-in-Metal-Furniture-Cups-with-Grey-Carpet-Base-4-Pack-804674/306229444 They slide super easily when I need to move them.
I use the same on my hardwoods and they work great! Slide games around all the time with ease.
