Leg leveler rust is a great problem at hand but you can also use furniture
leg cups that are made of plastic. They come in different sizes and colors
and are available at Home Depot and other home improvement stores. They
also work great if your game is on a tile or vinyl floor. It helps keep
them in place if you put a little double sided tape on the bottom of the cup
and your pin will stay put and not eat up your floor. Also try
self-adhesive Velcro (hook side) on the bottom, for the carpet if you
have low pile or indoor/outdoor carpet and your game tends to slide around.
