Crokinole

Often in tabletop crokinole play, the "sand" isn't even used. Modern boards are often slick enough to get away with playing without it, and if it's a board that you roll out regularly, you may not want the cleanup overhead associated with using shuffleboard "sand."

Also note that you'd never use actual sand on a crokinole board or tabletop shuffleboard. Sand, wax, or powder is what the shuffleboard products are referred to as and are made of specially formulated silicone beads (much less abrasive than, say, beach sand) or cornmeal, or even sometimes ground walnut shells.

you don't use those shuffleboard wax beads, you use 'gliss powder' which is often boric acid powder, or like even tinier, microbeads. the stuff the use on those shffleboards you find in pubs is much to corse. https://www.maydaygames.com/products/crokinole-premium-gliss...
