+summary: Clear the screen by removing groups of colored and shaped tiles
+description: |
+  Remove as many squares as possible from the board. Click on a group of
+  squares of the same color to make them all disappear in one fell swoop,
+  causing other squares to fall into place. It is not possible to remove a
+  single square at a time. You get far more points for clearing a larger group
+  of squares, and also for clearing the entire board.
+
+  Swell Foop is always very quick to play, but you can make it somewhat longer
+  by changing the board size.
