These are high-quality forcing dice that lend themselves to inventing a new routine or two, or
freshening up an old one. I like these so much that I’m going to order a second set posthaste for a
routine I have in mind, with the added advantage of having a matching “normal” pair for switching
out or other uses.
If you spend a little time with them, you’ll learn a shortcut for
determining which number is forced.
