+  <p>
+   Quadrapassel is a derivitive of the classic Russian falling-block game.
+   Reposition and rotate the blocks as they fall, and attempt to fit them
+   together. When you form a complete horizontal row of blocks, the row will
+   disappear and you score points. The game is over when the blocks get stacked
+   too high. As your score gets higher, you level up and the blocks fall faster.
+  </p>
+  <p>
+   If you're looking for a challenge, Quadrapassel allows you to increase the
+   initial speed of the blocks, or begin the game with partial blocks on some
+   of the rows. Or, instead of allowing the blocks to fall randomly, it can
+   select blocks that will be hard for you to place.
+  </p>
