The Second Edition has several changes from the First Edition:
1) New clear plastic soap-dish style deck case instead of cardboard tuckbox.
2) Cards are 2.5" x 3.5" (poker sized) instead of 2.25" x 3.5" (bridge sized).
3) Deck is 27 instead of 28 cards. Quick Reference Cards were removed, and placed in the rules instead.
4) Boxes are signed by the author, instead of individually serial numbered.
