+One-Deck game type. 1 deck. No redeal.
+
+<h3>Object</h3>
+<p>
+Move all the cards to the foundations.
+
+<h3>Rules</h3>
+<p>
+Cards are dealt from the talon one at a time, and can be moved to
+one of three foundations.  Any card can be used to start the foundations,
+and they are then built up by same suit or rank.  No redeal is allowed.
+The game is won if all cards are moved to the foundations.
