+<h1>Guardian</h1>
+<p>
+Klondike type. 1 deck. Unlimited redeals.
+
+<h3>Object</h3>
+<p>
+Move all cards to the foundations.
+
+<h3>Rules</h3>
+<p>
+The tableau piles are built in a pyramid-esque layout, with five cards
+in the top layer, four cards in the middle, and three in the bottom.
+Each card forms a tableau pile which can be built down by alternate
+color.  The three bottom layer cards can be filled with any card when
+empty, but the remaining layers cannot be filled.  Cards in the lower
+layers can only be flipped if the two cards overlapping them are
+removed.
+<p>
+Foundations are built up in suit from Ace to King.
+<p>
+Cards are dealt from the stock three at a time, and can be moved to
+foundations or exposed tableau piles.  You can go through the deck
+as many times as needed.
+<p>
+The game is won when all cards are moved to the foundations.
+
+<h3>Notes</h3>
+<p>
+The name of the game comes from the way a single card (especially an
+immovable king) can "guard" multiple cards beneath them.
