The cube is available via mail order from:
LOGICAL GAMES, Inc
4509 Martinwood Dr.
Haymarket, VA 22069
I have not tried it, so there is no guarantee. I found an ad
in some magazine (i do not remember, but could find it if some one
wants to know the type of mag.). They ask you to send $9 for the cube,
and/or $4 for "notes on the magic cube". VA residents to add sales tax.
Or you can do what I did, telephone every toy store in the area,
till you find one that stocks it.
