+<h1>The Spark</h1>
+<p>
+Forty Thieves type. 2 decks. No redeal.
+
+<h3>Object</h3>
+<p>
+Move all cards to the foundations.
+
+<h3>Rules</h3>
+<p>
+Twelve cards are dealt into twelve tableau piles.  These
+piles are built down by suit.  Only one card can be moved
+at a time.  Any card can be used to fill empty piles in the
+tableau.  The kings are dealt to eight foundation piles,
+which are built up by same suit, wrapping from king to ace
+as necessary.
+<p>
+Cards from the talon are dealt to two waste piles, three
+cards at a time to each.  The top card from either waste pile
+can be moved to a tableau or foundation pile.  The game is won
+if all the cards are moved to the foundation piles.
