+    (description "Blinken is based on an electronic game released in 1978,
+which challenges players to remember sequences of increasing length.  On the
+face of the device, there are 4 different color buttons, each with its own
+distinctive sound.  These buttons light up randomly, creating the sequence
+that the player must then recall.  If the player is successful in remembering
+the sequence of lights in the correct order, they advance to the next stage,
+where an identical sequence with one extra step is presented.
