+<h1>Step-Up</h1>
+<p>
+Two-Deck game type. 2 decks. No redeal.
+
+<h3>Object</h3>
+<p>
+Move all the cards to the upper step/foundations.
+
+<h3>Rules</h3>
+<p>
+At the start of the game, single cards are dealt to 13 reserve piles, 
+and nine tableau piles directly below the reserve.  The tableau piles
+are called the "lower step" while the reserves are called the "middle
+step".  A single card is dealt to a foundation pile above - the foundations
+are called the "upper step".  This first card determines the base rank of
+the foundation.
+<p>
+Piles in the lower step are built down by alternating color, wrapping from
+ace to king as needed.  Any card can be used to fill an empty pile in the
+lower step, but only single cards may be moved.  No building is allowed in
+the middle step.  Cards from the lower step can be moved to empty piles in the
+middle step, but not the other way around.  Cards can only be moved to the
+foundation from the middle step or the waste (they may be moved directly
+from the lower step if there's an empty pile in the middle step).
+<p>
+Cards can be dealt from the talon to the waste one at a time, though if there
+is an empty pile in the middle step, only three cards can be dealt from the
+talon before it must be filled.  Cards from the waste can be dealt to any
+of the three steps.  No redeal is allowed.  The game is won if all cards
+are moved to the upper step/foundations.
