I used an old table top that was lying around.
This bit works best for the marble holders, as an alternative you could drill holes and use wooden golf tees instead of marbles.
Used a standard 1/16 end mill bit for all the rest of the carving.
use a 1/4 end mill for the outside , I ran it about 3/8 down and cut the rest out with jig saw and finished with a hand router.
I paint , so i had several colors of acrylics around the house, finished it of with lacquer. below is a link to where i bought game marbles. I bought these because a made 2 different games you could probably find just enough cheaper.
