-.TH BLUE 6 "Nov 31 1994"
-.SH NAME
-blue \- Blue Moon
-.SH SYNOPSIS
-blue
-.SH DESCRIPTION
-This 52-card solitaire starts with the entire deck shuffled and dealt
-out in four rows. The aces are then moved to the left end of the layout,
-making 4 initial free spaces. You may move to a space only the card that
-matches the left neighbor in suit, and is one greater in rank. Kings are
-high, so no cards may be placed to their right (they create dead spaces).
-.P
-When no moves can be made, cards still out of sequence are reshuffled
-and dealt face up after the ends of the partial sequences, leaving a card
-space after each sequence, so that each row looks like a partial sequence
-followed by a space, followed by enough cards to make a row of 14.
-.P
-A moment's reflection will show that this game cannot take more than 13
-deals. A good score is 1-3 deals, 4-7 is average, 8 or more is poor.

-November 1994. See http://www.ccil.org/~esr/home.html for updates, also
